Modeling spectral tuning in monomeric teal fluorescent protein mTFP1.

ABSTRACT: We present results of theoretical studies of the variants of the monomeric teal fluorescent protein from Clavularia coral (mTFP1) which present promising members from the GFP family. Predictions of quantum chemical approaches including density functional theory and semiempirical approximations are presented for the model systems which mimic the chromophores in different environments. We describe the excitation energy spectrum of the cyan mTFP1 fluorescent protein with the original chromophore and with chromophore mutants Tyr67His and Tyr67Trp.

Fine spectral tuning of a flavin-binding fluorescent protein for multicolor imaging.

Project description:Flavin-binding fluorescent proteins are promising genetically encoded tags for microscopy. However, spectral properties of their chromophores (riboflavin, flavin mononucleotide, and flavin adenine dinucleotide) are notoriously similar even between different protein families, which limits applications of flavoproteins in multicolor imaging. Here, we present a palette of 22 finely tuned fluorescent tags based on the thermostable LOV domain from Chloroflexus aggregans. We performed site saturation mutagenesis of three amino acid positions in the flavin-binding pocket, including the photoactive cysteine, to obtain variants with fluorescence emission maxima uniformly covering the wavelength range from 486 to 512 nm. We demonstrate three-color imaging based on spectral separation and two-color fluorescence lifetime imaging of bacteria, as well as two-color imaging of mammalian cells (HEK293T), using the proteins from the palette. These results highlight the possibility of fine spectral tuning of flavoproteins and pave the way for further applications of flavin-binding fluorescent proteins in fluorescence microscopy.

A monomeric red fluorescent protein.

Project description:All coelenterate fluorescent proteins cloned to date display some form of quaternary structure, including the weak tendency of Aequorea green fluorescent protein (GFP) to dimerize, the obligate dimerization of Renilla GFP, and the obligate tetramerization of the red fluorescent protein from Discosoma (DsRed). Although the weak dimerization of Aequorea GFP has not impeded its acceptance as an indispensable tool of cell biology, the obligate tetramerization of DsRed has greatly hindered its use as a genetically encoded fusion tag. We present here the stepwise evolution of DsRed to a dimer and then either to a genetic fusion of two copies of the protein, i.e., a tandem dimer, or to a true monomer designated mRFP1 (monomeric red fluorescent protein). Each subunit interface was disrupted by insertion of arginines, which initially crippled the resulting protein, but red fluorescence could be rescued by random and directed mutagenesis totaling 17 substitutions in the dimer and 33 in mRFP1. Fusions of the gap junction protein connexin43 to mRFP1 formed fully functional junctions, whereas analogous fusions to the tetramer and dimer failed. Although mRFP1 has somewhat lower extinction coefficient, quantum yield, and photostability than DsRed, mRFP1 matures >10 times faster, so that it shows similar brightness in living cells. In addition, the excitation and emission peaks of mRFP1, 584 and 607 nm, are approximately 25 nm red-shifted from DsRed, which should confer greater tissue penetration and spectral separation from autofluorescence and other fluorescent proteins.

A photostable monomeric superfolder green fluorescent protein.

Project description:The green fluorescent protein (GFP) from Aequorea victoria has been engineered extensively in the past to generate variants suitable for protein tagging. Early efforts produced the enhanced variant EGFP and its monomeric derivative mEGFP, which have useful photophysical properties, as well as superfolder GFP, which folds efficiently under adverse conditions. We previously generated msGFP, a monomeric superfolder derivative of EGFP. Unfortunately, compared to EGFP, msGFP and other superfolder GFP variants show faster photobleaching. We now describe msGFP2, which retains monomeric superfolder properties while being as photostable as EGFP. msGFP2 contains modified N- and C-terminal peptides that are expected to reduce nonspecific interactions. Compared to EGFP and mEGFP, msGFP2 is less prone to disturbing the functions of certain partner proteins. For general-purpose protein tagging, msGFP2 may be the best available derivative of A. victoria GFP.

Nontemplated approach to tuning the spectral properties of cyanine-based fluorescent nanoGUMBOS.

Project description:Template-free controlled aggregation and spectral properties in fluorescent organic nanoparticles (FONs) is highly desirable for various applications. Herein, we report a nontemplated method for controlling the aggregation in near-infrared (NIR) cyanine-based nanoparticles derived from a group of uniform materials based on organic salts (GUMBOS). Cationic heptamethine cyanine dye 1,1',3,3,3',3'-hexamethylindotricarbocyanine (HMT) was coupled with five different anions, viz., [NTf(2)(-)], [BETI(-)], [TFPB(-)], [AOT(-)], and [TFP4B(-)], by an ion-exchange method to obtain the respective GUMBOS. The nanoGUMBOS obtained via a reprecipitation method were primarily amorphous and spherical (30-100 nm) as suggested by selected area electron diffraction (SAED) and transmission electron microscopy (TEM). The formation of tunable self-assemblies within the nanoGUMBOS was characterized using absorption and fluorescence spectroscopy in conjunction with molecular dynamics simulations. Counterion-controlled spectral properties observed in the nanoGUMBOS were attributed to variations in J/H ratios with different anions. Association with the [AOT(-)] anion afforded predominant J aggregation enabling the highest fluorescence intensity, whereas [TFP4B(-)] disabled the fluorescence due to predominant H aggregation in the nanoparticles. Analyses of the stacking angle of the cations based on molecular dynamic simulation results in [HMT][NTf(2)], [HMT][BETI], and [HMT][AOT] dispersed in water and a visual analysis of the representative simulation snapshots also imply that the type of aggregation was controlled through the counterion associated with the dye cation.

A naturally monomeric infrared fluorescent protein for protein labeling in vivo.

Project description:Infrared fluorescent proteins (IFPs) provide an additional color to GFP and its homologs in protein labeling. Drawing on structural analysis of the dimer interface, we identified a bacteriophytochrome in the sequence database that is monomeric in truncated form and engineered it into a naturally monomeric IFP (mIFP). We demonstrate that mIFP correctly labels proteins in live cells, Drosophila and zebrafish. It should be useful in molecular, cell and developmental biology.

The molecular basis of spectral tuning in blue- and red-shifted flavin-binding fluorescent proteins.

Project description:Photoactive biological systems modify the optical properties of their chromophores, known as spectral tuning. Determining the molecular origin of spectral tuning is instrumental for understanding the function and developing applications of these biomolecules. Spectral tuning in flavin-binding fluorescent proteins (FbFPs), an emerging class of fluorescent reporters, is limited by their dependency on protein-bound flavins, whose structure and hence electronic properties cannot be altered by mutation. A blue-shifted variant of the plant-derived improved light, oxygen, voltage FbFP has been created by introducing a lysine within the flavin-binding pocket, but the molecular basis of this shift remains unconfirmed. We here structurally characterize the blue-shifted improved light, oxygen, voltage variant and construct a new blue-shifted CagFbFP protein by introducing an analogous mutation. X-ray structures of both proteins reveal displacement of the lysine away from the chromophore and opening up of the structure as instrumental for the blue shift. Site saturation mutagenesis and high-throughput screening yielded a red-shifted variant, and structural analysis revealed that the lysine side chain of the blue-shifted variant is stabilized close to the flavin by a secondary mutation, accounting for the red shift. Thus, a single additional mutation in a blue-shifted variant is sufficient to generate a red-shifted FbFP. Using spectroscopy, X-ray crystallography, and quantum mechanics molecular mechanics calculations, we provide a firm structural and functional understanding of spectral tuning in FbFPs. We also show that the identified blue- and red-shifted variants allow for two-color microscopy based on spectral separation. In summary, the generated blue- and red-shifted variants represent promising new tools for application in life sciences.

Photoperiodic spectral tuning of carbon metabolism in heterotrophic marine flavobacteria

Project description:Influence of the constant full-spectrum light and short-to-long wavelengths of the visible spectrum (red, green and blue lights) and the significance of 12 h photoperiod was tested on heterotrophic marine flavobacteria Siansivirga zeaxanthinifaciens CC-SAMT-1T. RNA-seq analysis revealed remarkable qualitative and quantitative variations in terms of gene expression in CC-SAMT-1T with respect to incident lights. While blue light illumination stimulated expression of genes involved in inorganic carbon metabolism, green˗red lights largely upregulated the genes participating in high-molecular-weight (HMW) organic carbon metabolism. Constant full-spectrum light also displayed the upregulation of genes involved in the metabolism of HMW organic carbon. Thus, the short-to-long wavelengths of visible light and the 12 h photoperiod most likely to play a key role in the marine carbon cycle by tuning heterotrophic bacterial metabolism.

Green monomeric photosensitizing fluorescent protein for photo-inducible protein inactivation and cell ablation.

Project description:BACKGROUND:Photosensitizing fluorescent proteins, which generate reactive oxygen species (ROS) upon light irradiation, are useful for spatiotemporal protein inactivation and cell ablation. They give us clues about protein function, intracellular signaling pathways and intercellular interactions. Since ROS generation of a photosensitizer is specifically controlled by certain excitation wavelengths, utilizing colour variants of photosensitizing protein would allow multi-spatiotemporal control of inactivation. To expand the colour palette of photosensitizing protein, here we developed SuperNova Green from its red predecessor, SuperNova. RESULTS:SuperNova Green is able to produce ROS spatiotemporally upon blue light irradiation. Based on protein characterization, SuperNova Green produces insignificant amounts of singlet oxygen and predominantly produces superoxide and its derivatives. We utilized SuperNova Green to specifically inactivate the pleckstrin homology domain of phospholipase C-?1 and to ablate cancer cells in vitro. As a proof of concept for multi-spatiotemporal control of inactivation, we demonstrate that SuperNova Green can be used with its red variant, SuperNova, to perform independent protein inactivation or cell ablation studies in a spatiotemporal manner by selective light irradiation. CONCLUSION:Development of SuperNova Green has expanded the photosensitizing protein toolbox to optogenetically control protein inactivation and cell ablation.

A Modified Monomeric Red Fluorescent Protein Reporter for Assessing CRISPR Activity.

Project description:Gene editing in human embryonic stem cells (hESCs) has been significantly enhanced by the discovery and development of CRISPR Cas9, a programmable nuclease system that can introduce targeted double-stranded breaks. The system relies on the optimal selection of a sgRNA sequence with low off-targets and high efficiency. We designed an improved monomeric red fluorescent protein reporter, GEmCherry2, for assessing CRISPR Cas9 activity and for optimizing sgRNA. By incorporating an out-of-frame sequence to the N-terminal of the red fluorescent protein mCherry, we created a visual tool for assessing the indel frequency after cutting with CRISPR Cas9. When a sgRNA-Cas9 construct is co-transfected with a corresponding GEmCherry2 construct, single nucleotide indels can move the GEmCherry2 sequence back in-frame and allow quantification and comparison of the efficiency of different sgRNA target sites by measuring red fluorescence. With this GEmCherry2 assay, we compared four target sites in the safe harbor AAVS1 locus and found significant differences in target site activity. We verified the activity using TIDE, which ranked our target sites in a similar order as the GEmCherry2 system. We also identified an AAV short inverted terminal repeat sequence within the Cas9 construct that, upon removal significantly improved transient transfection and expression in hESCs. Moreover, using GEmCherry2, we designed a sgRNA to target SORCS2 in hESCs and successfully introduced indels into the coding sequence of SORCS2.
