Genetically encoded cyclopropene directs rapid, photoclick-chemistry-mediated protein labeling in mammalian cells.

ABSTRACT: We just click: Genetic incorporation of a cyclopropene amino acid CpK (see scheme) site-specifically into proteins in E.?coli and mammalian cells was achieved using an orthogonal aminoacyl-tRNA synthetase/tRNA(CUA) pair (CpKRS/MbtRNA(CUA)). Cyclopropene exhibited fast reaction kinetics in the photoclick reaction and allowed rapid (ca. 2?min) labeling of proteins.

A genetically encoded alkyne directs palladium-mediated protein labeling on live mammalian cell surface.

Project description:The merging of site-specific incorporation of small bioorthogonal functional groups into proteins via amber codon suppression with bioorthogonal chemistry has created exciting opportunities to extend the power of organic reactions to living systems. Here we show that a new alkyne amino acid can be site-selectively incorporated into mammalian proteins via a known orthogonal pyrrolysyl-tRNA synthetase/tRNACUA pair and directs an unprecedented, palladium-mediated cross-coupling reaction-driven protein labeling on live mammalian cell surface. A comparison study with the alkyne-encoded proteins in vitro indicated that this terminal alkyne is better suited for the palladium-mediated cross-coupling reaction than the copper-catalyzed click chemistry.

Fluorogenic, two-photon-triggered photoclick chemistry in live mammalian cells.

Project description:The tetrazole-based photoclick chemistry has provided a powerful tool to image proteins in live cells. To extend photoclick chemistry to living organisms with improved spatiotemporal control, here we report the design of naphthalene-based tetrazoles that can be efficiently activated by two-photon excitation with a 700 nm femtosecond pulsed laser. A water-soluble, cell-permeable naphthalene-based tetrazole was identified that reacts with acrylamide with the effective two-photon cross-section for the cycloaddition reaction determined to be 3.8 GM. Furthermore, the use of this naphthalene-tetrazole for real-time, spatially controlled imaging of microtubules in live mammalian cells via the fluorogenic, two-photon-triggered photoclick chemistry was demonstrated.

Genetically encoded norbornene directs site-specific cellular protein labelling via a rapid bioorthogonal reaction.

Project description:The site-specific incorporation of bioorthogonal groups via genetic code expansion provides a powerful general strategy for site-specifically labelling proteins with any probe. However, the slow reactivity of the bioorthogonal functional groups that can be encoded genetically limits the utility of this strategy. We demonstrate the genetic encoding of a norbornene amino acid using the pyrrolysyl tRNA synthetase/tRNA(CUA) pair in Escherichia coli and mammalian cells. We developed a series of tetrazine-based probes that exhibit 'turn-on' fluorescence on their rapid reaction with norbornenes. We demonstrate that the labelling of an encoded norbornene is specific with respect to the entire soluble E. coli proteome and thousands of times faster than established encodable bioorthogonal reactions. We show explicitly the advantages of this approach over state-of-the-art bioorthogonal reactions for protein labelling in vitro and on mammalian cells, and demonstrate the rapid bioorthogonal site-specific labelling of a protein on the mammalian cell surface.

Genetically encoded tetrazine amino acid directs rapid site-specific in vivo bioorthogonal ligation with trans-cyclooctenes.

Project description:Bioorthogonal ligation methods with improved reaction rates and less obtrusive components are needed for site-specifically labeling proteins without catalysts. Currently no general method exists for in vivo site-specific labeling of proteins that combines fast reaction rate with stable, nontoxic, and chemoselective reagents. To overcome these limitations, we have developed a tetrazine-containing amino acid, 1, that is stable inside living cells. We have site-specifically genetically encoded this unique amino acid in response to an amber codon allowing a single 1 to be placed at any location in a protein. We have demonstrated that protein containing 1 can be ligated to a conformationally strained trans-cyclooctene in vitro and in vivo with reaction rates significantly faster than most commonly used labeling methods.

Genetically Encoded Protein Phosphorylation in Mammalian Cells.

Project description:Protein phosphorylation regulates diverse processes in eukaryotic cells. Strategies for installing site-specific phosphorylation in target proteins in eukaryotic cells, through routes that are orthogonal to enzymatic post-translational modification, would provide a powerful route for defining the consequences of particular phosphorylations. Here we show that the SepRSv1.0/tRNAv1.0CUA pair (created from the Methanococcus maripaludis phosphoseryl-transfer RNA synthetase [MmSepRS]/Methanococcus janaschii [Mj]tRNAGCACys pair) is orthogonal in mammalian cells. We create a eukaryotic elongation factor 1 alpha (EF-1?) variant, EF-1?-Sep, that enhances phosphoserine incorporation, and combine this with a mutant of eRF1, and manipulations of the cell's phosphoserine biosynthetic pathway, to enable the genetically encoded incorporation of phosphoserine and its non-hydrolyzable phosphonate analog. Using this approach we demonstrate synthetic activation of a protein kinase in mammalian cells.

Genetically encoded protein sulfation in mammalian cells.

Project description:Tyrosine sulfation is an important post-translational modification found in higher eukaryotes. Here we report an engineered tyrosyl-tRNA synthetase/tRNA pair that co-translationally incorporates O-sulfotyrosine in response to UAG codons in Escherichia coli and mammalian cells. This platform enables recombinant expression of eukaryotic proteins homogeneously sulfated at chosen sites, which was demonstrated by expressing human heparin cofactor II in mammalian cells in different states of sulfation.

Fluorogenic protein labeling using a genetically encoded unstrained alkene.

Project description:We developed a new fluorogenic bioorthogonal reaction that is based on the inverse electron-demand Diels-Alder reaction between styrene (an unstrained alkene) and a simple tetrazine. The reaction forms a new fluorophore with no literature precedent. We have identified an aminoacyl-tRNA synthetase/tRNA pair for the efficient and site-specific incorporation of a styrene-containing amino acid into proteins in response to amber nonsense codon. Fluorogenic labeling of purified proteins and intact proteins in live cells were demonstrated. The fluorogenicity of the styrene-tetrazine reaction can be potentially applied to the study of protein folding and function under physiological conditions with low background fluorescence interference.

Design of spiro[2.3]hex-1-ene, a genetically encodable double-strained alkene for superfast photoclick chemistry.

Project description:Reactive yet stable alkene reporters offer a facile route to studying fast biological processes via the cycloaddition-based bioorthogonal reactions. Here, we report the design and synthesis of a strained spirocyclic alkene, spiro[2.3]hex-1-ene (Sph), for an accelerated photoclick chemistry, and its site-specific introduction into proteins via amber codon suppression using the wild-type pyrrolysyl-tRNA synthetase/tRNA(CUA) pair. Because of its high ring strain and reduced steric hindrance, Sph exhibited fast reaction kinetics (k2 up to 34,000 M(-1) s(-1)) in the photoclick chemistry and afforded rapid (<10 s) bioorthogonal protein labeling.

A genetically encoded fluorescent probe in mammalian cells.

Project description:Fluorescent reporters are useful in vitro and in vivo probes of protein structure, function, and localization. Here we report that the fluorescent amino acid, 3-(6-acetylnaphthalen-2-ylamino)-2-aminopropanoic acid (Anap), can be site-specifically incorporated into proteins in mammalian cells in response to the TAG codon with high efficiency using an orthogonal amber suppressor tRNA/aminoacyl-tRNA synthetase (aaRS) pair. We further demonstrate that Anap can be used to image the subcellular localization of proteins in live mammalian cells. The small size of Anap, its environment-sensitive fluorescence, and the ability to introduce Anap at specific sites in the proteome by simple mutagenesis make it a unique and valuable tool in eukaryotic cell biology.

Genetically Encoded Protein Tyrosine Nitration in Mammalian Cells.

Project description:Tyrosine nitration has served as a major biomarker for oxidative stress and is present in high abundance in over 50 disease pathologies in humans. While data mounts on specific disease pathways from specific sites of tyrosine nitration, the role of these modifications is still largely unclear. Strategies for installing site-specific tyrosine nitration in target proteins in eukaryotic cells, through routes not dependent on oxidative stress, would provide a powerful method to address the consequences of tyrosine nitration. Developed here is a Methanosarcina barkeri aminoacyl-tRNA synthetase/tRNA pair that efficiently incorporates nitrotyrosine site-specifically into proteins in mammalian cells. We demonstrate the utility of this approach to produce nitrated proteins identified in disease conditions by producing site-specific nitroTyr-containing manganese superoxide dismutase and 14-3-3 proteins in eukaryotic cells.
