[Endeavors to make the photophore, diazirine easy to use].
Photoaffinity labeling enables the direct probing of a target protein through a covalent bond between a ligand and its binding protein. We used carbene-generating phenyldiazirine as a photophore because practical examinations had shown that the phenyldiazirine functioned as the powerful barb on the hook. This review describes improvements of synthetic strategies of the photoaffinity ligands bea...
متن کامل3-Trifluoromethyl-3-aryldiazirine photolabels with enhanced ambient light stability.
Ambient light stable 3-trifluoromethyl-3-aryldiazirine photolabels are developed via stabilization of the strained three membered diazirine ring by replacing the phenyl ring with electron withdrawing heterocyclic rings. Photolabeling studies reveal that these ambient light stable photolabels are equally efficient in photolabeling target proteins as the traditional 3-trifluoromethyl-3-phenyldiaz...
متن کاملPositively coded photoaffinity label for altering isoelectric points of proteins.
Novel diazirinyl photoaffinity ligand, which contains (3-trifluoromethyl) phenyldiazirine and penta(epsilon-Boc-Lys) as a photoreactive code, allows the introduction of a positive cascade to alter the pI value of labeled components, facilitating the isolation of photolabeled biocomponents with isoelectric focusing techniques.
متن کاملDistinct metabolites for photoreactive L-phenylalanine derivatives in Klebsiella sp. CK6 isolated from rhizosphere of a wild dipterocarp sapling.
Photoaffinity labeling is a reliable analytical method for biological functional analysis. Three major photophores--aryl azide, benzophenone and trifluoromethyldiazirine--are utilized in analysis. Photophore-bearing L-phenylalanine derivatives, which are used for biological functional analysis, were inoculated into a Klebsiella sp. isolated from the rhizosphere of a wild dipterocarp sapling in ...
متن کاملDevelopment and leading-edge application of innovative photoaffinity labeling.
Photoaffinity labeling has become increasingly important with the development of powerful specific probes that are synthesized by installing a photo-activatable functional group (photophore) on the framework of biological ligands. The present review summarizes the development of diazirine-based photoaffinity labeling by focusing on its application to the structural elucidation of ligand-accepti...
