Modified DNA strands undergo a reversible light-induced reaction involving the intramolecular photodimerization of two appended anthracene tags. The photodimers exhibit markedly different binding behavior toward a complementary strand that depends on the number of bases between the modified positions. By preforming the duplex, photochromism can be suppressed, illustrating dual-mode gated behavior. ...[more]

Project description:Photocontrolled transcription factors could be powerful tools for probing the roles of transcriptional processes in a variety of settings. Previously, we designed a photocontrolled DNA-binding protein based on a fusion between the bZIP region of GCN4 and photoactive yellow protein from Halorhodospira halophila [Morgan, S. A., et al. (2010) J. Mol. Biol. 399, 94-112]. Here we report a structure-based attempt to improve the degree of photoswitching observed with this chimeric protein. Using computational design tools PoPMuSiC 2.0, Rosetta, Eris, and bCIPA, we identified a series of single- and multiple-point mutations that were expected to stabilize the folded dark state of the protein and thereby enhance the degree of photoswitching. While a number of these mutations, particularly those that introduced a hydrophobic residue at position 143, did significantly enhance dark-state protein stability as judged by urea denaturation studies, dark-state stability did not correlate directly with the degree of photoswitching. Instead, the influence of mutations on the degree of photoswitching was found to be related to their effects on the degree to which DNA binding slowed the pB to pG transition in the PYP photocycle. One mutant, K143F, caused an ∼10-fold slowing of the photocycle and also showed the largest difference in the apparent K(d) for DNA binding, 3.5-fold lower, upon irradiation. This change in the apparent K(d) causes a 12-fold enhancement in the fraction bound DNA upon irradiation due to the cooperativity of DNA binding by this family of proteins. The results highlight the strengths and weaknesses of current approaches to a practical problem in protein design and suggest strategies for further improvement of designed photocontrolled transcription factors.

Project description:Azobenzenes are photoswitchable molecules capable of generating significant structural changes upon E-to-Z photoisomerization in peptides or small molecules, thereby controlling geometry and functionality. E-to-Z photoisomerization usually is achieved upon irradiation at 350 nm (?-?* transition), while the Z-to-E isomerization proceeds photochemically upon irradiation at >400 nm (n-?* transition) or thermally. Photoswitchable compounds have frequently been employed as modules, e.g., to control protein-DNA interactions. However, their use in conjunction with minor groove-binding imidazole/pyrrole (Im/Py) polyamides is yet unprecedented. Dervan-type Im/Py polyamides were equipped with an azobenzene unit, i.e., 3-(3-(aminomethyl)phenyl)azophenylacetic acid, as the linker between two Im/Py polyamide strands. Only the (Z)-azobenzene-containing polyamides bound to the minor groove of double-stranded DNA hairpins. Photoisomerization was exemplarily evaluated by 1H NMR experiments, while minor groove binding of the (Z)-azobenzene derivatives was proven by CD titration experiments. The resulting induced circular dichroism (ICD) bands of the bound ligands, together with the photometric determination of the dsDNA melting temperature, revealed a significant stabilization of the DNA upon association with the ligand. The (Z)-azobenzene acted as a building block inducing a reverse turn, which favored hydrogen bonds between the pyrrole/imidazole amide and the DNA bases. In contrast, the E-configured polyamides did not induce any ICD characteristic for minor groove binding. The incorporation of the photoswitchable azobenzene unit is a promising strategy to obtain photoswitchable Im/Py hairpin polyamides capable of interacting with the dsDNA minor groove only in the Z-configuration.

Project description:Temporal and spatial control over polydopamine formation on the nanoscale can be achieved by installing an irradiation-sensitive polymerization system on DNA origami. Precisely distributed G-quadruplex structures on the DNA template serve as anchors for embedding the photosensitizer protoporphyrin IX, which-upon irradiation with visible light-induces the multistep oxidation of dopamine to polydopamine, producing polymeric structures on designated areas within the origami framework. The photochemical polymerization process allows exclusive control over polydopamine layer formation through the simple on/off switching of the light source. The obtained polymer-DNA hybrid material shows significantly enhanced stability, paving the way for biomedical and chemical applications that are typically not possible owing to the sensitivity of DNA.

Project description:Three new cadmium coordination polymers, namely [Cd(NO₃)₂(DPNDI)(CH₃OH)]·CH₃OH (1), [Cd(SCN)₂(DPNDI)] (2), and [Cd(DPNDI)₂(DMF)₂]·2ClO₄ (3) (DPNDI = N,N-di(4-pyridyl)-1,4,5,8-naphthalene diimide, DMF = N,N-dimethylformamide) have been synthesized by reactions of DPNDI with Cd(NO₃)₂, Cd(SCN)₂, and Cd(ClO₄)₂, respectively. Compound 1 is a one-dimensional coordination polymer with strong lone pair-π interactions between the coordinated NO₃- anions and the imide ring of DPNDI; while 2 is a two-dimensional network with a (4, 4) net topology. In the case of 3, due to the presence of uncoordinated perchlorate counter ions, it exhibits a non-interpenetrated square-grid coordination polymer containing one-dimensional rhomboid channels. The structural diversity in these compounds is attributed to different coordination abilities and geometries of counter anions. Due to the presence of electron-deficient NDI moiety, the photochromic behavior of these compounds was studied. Interestingly, only compounds 1 and 3 exhibit color changes under light irradiation. The influence of the anions on the photochromism process of the NDI-based materials has been discussed.

Project description:Proteins in the HMG family are important transcription factors. They recognize cisplatin-damaged DNA lesions with a structure-specific preference and account for more than 70% of all proteins that interact with the cisplatin 1,2-intrastrand d(GpG) cross-link. HMGB4, a new member of the mammalian HMGB protein family expressed preferentially in the testis, was generated recombinantly, and its interactions with cisplatin-modified DNA were investigated in vitro. The binding affinities of the two individual DNA-binding domains of HMGB4 to DNA carrying a cisplatin 1,2-intrastrand d(GpG) cross-link are weaker than those of the DNA-binding domains of HMGB1. Full-length HMGB4, however, has a 28-fold stronger binding affinity (K(d) = 4.35 nM) for the platinated adduct compared to that of HMGB1 (K(d) = 120 nM), presumably because the former lacks a C-terminal acidic tail. The residue Phe37 plays a critical role in stabilizing the binding complex of HMGB4 with the cisplatin-modified DNA, as it does for HMGB1. Hydroxyl radical footprinting analysis of the HMGB4/platinated DNA complex reveals a footprinting pattern very different from that of HMGB1, however, revealing very little binding asymmetry with respect to the platinated lesion. An in vitro repair assay revealed that HMGB4, at 1 μM, interferes with repair of cisplatin 1,2-intrastrand cross-link damage by >90% compared to control, whereas HMGB1 at the same concentration inhibits repair by 45%. This repair inhibition capability is highly dependent on both the binding affinity and the size of the proteins. The putative role of HMGB4 in the mechanism of action of cisplatin, and especially its potential relevance to the hypersensitivity of testicular germ cell tumors to cisplatin, are discussed.

Project description:A light-driven artificial molecular nanomachine was constructed based on DNA scaffolding. Pyrene-modified walking strands and disulfide bond-connected stator strands, employed as anchorage sites to support walker movement, were assembled into a 2D DNA tile. Pyrene molecules excited by photoirradiation at 350 nm induced cleavage of disulfide bond-connected stator strands, enabling the DNA walker to migrate from one cleaved stator to the next on the DNA tile. The time-dependent movement of the walker was observed and the entire walking process of the walker was characterized by distribution of the walker-stator duplex at four anchorage sites on the tile under different irradiation times. Importantly, the light-fuelled mechanical movements on DNA tile were first visualized in real time during UV irradiation using high-speed atomic force microscopy (HS-AFM).

Project description:Laccase, a multicopper oxidase, catalyses the four electron reduction of oxygen to water. Upon adsorption to an electrode surface, laccase is known to reduce oxygen at overpotentials lower than the best noble metal electrocatalysts usually employed. While the electrocatalytic activity of laccase is well established on carbon electrodes, laccase does not typically adsorb to better defined noble metal surfaces in an orientation that allows for efficient electrocatalysis. In this work, we utilized anthracene-2-methanethiol (AMT) to modify the surface of Au electrodes and examined the electrocatalytic activity of adsorbed laccase. AMT facilitated the adsorption of laccase, and the onset of electrocatalytic oxygen reduction was observed as high as 1.13 V(RHE). We observed linear Tafel behavior with a 144 mV/dec slope, consistent with an outer sphere single electron transfer from the electrode to a Cu site in the enzyme as the rate determining step of the oxygen reduction mechanism.

Project description:The heterodimer of the ecdysone receptor (EcR) and ultraspiracle (Usp), members of the nuclear receptors superfamily, is considered as the functional receptor for ecdysteroids initiating molting and metamorphosis in insects. Here we report the 1.95 A structure of the complex formed by the DNA-binding domains (DBDs) the EcR and the Usp, bound to the natural pseudopalindromic response element. Comparison of the structure with that obtained previously, using an idealized response element, shows how the EcRDBD, which has been previously reported to possess extraordinary flexibility, accommodates DNA-induced structural changes. Part of the C-terminal extension (CTE) of the EcRDBD folds into an alpha-helix whose location in the minor groove does not match any of the locations previously observed for nuclear receptors. Mutational analyses suggest that the alpha-helix is a component of EcR-box, a novel element indispensable for DNA-binding and located within the nuclear receptor CTE. This element seems to be a general feature of all known EcRs.

Project description:Self-assembly is a fundamental feature of biological systems, and control of such processes offers fascinating opportunities to regulate function. Fragaceatoxin C (FraC) is a toxin that upon binding to the surface of sphingomyelin-rich cells undergoes a structural metamorphosis, leading to the assembly of nanopores at the cell membrane and causing cell death. In this study we attached photoswitchable azobenzene pendants to various locations near the sphingomyelin binding pocket of FraC with the aim of remote controlling the nanopore assembly using light. We found several constructs in which the affinity of the toxin for biological membranes could be activated or deactivated by irradiation, thus enabling reversible photocontrol of pore formation. Notably, one construct was completely inactive in the thermally adapted state; it however induced full lysis of cultured cancer cells upon light irradiation. Selective irradiation also allowed isolation of individual nanopores in artificial lipid membranes. Photocontrolled FraC might find applications in photopharmacology for cancer therapeutics and has potential to be used for the fabrication of nanopore arrays in nanopore sensing devices, where the reconstitution, with high spatiotemporal precision, of single nanopores must be controlled.

Project description:In contrast to the conventional passive reaction to analytes, here, we create a proof-of-concept nanochannel system capable of on-demand recognition of the target to achieve an unbiased response. Inspired by light-activatable biological channelrhodopsin-2, photochromic spiropyran/anodic aluminium oxide nanochannel sensors are constructed to realize a light-controlled inert/active-switchable response to SO2 by ionic transport behaviour. We find that light can finely regulate the reactivity of the nanochannels for the on-demand detection of SO2. Pristine spiropyran/anodic aluminium oxide nanochannels are not reactive to SO2. After ultraviolet irradiation of the nanochannels, spiropyran isomerizes to merocyanine with a carbon‒carbon double bond nucleophilic site, which can react with SO2 to generate a new hydrophilic adduct. Benefiting from increasing asymmetric wettability, the proposed device exhibits a robust photoactivated detection performance in SO2 detection in the range from 10 nM to 1 mM achieved by monitoring the rectified current.
