Submit ReviewDeazaflavin, Haloalkane is a deazaflavin-based organic photocatalyst covalently linked to a chloroalkane ligand via a short PEG linker. The conjugate enables site-specific tethering of the photocatalyst to proteins genetically fused to HaloTag® in live-cell systems.
Upon blue light illumination (~450 nm), the deazaflavin moiety transfers energy to nearby photoactivatable probes (e.g., diazirines, aryl azides), initiating localized covalent labeling of biomolecules in the immediate vicinity of the HaloTag® fusion protein. The process is dependent on light exposure, the presence of the reactive probe, and spatial proximity to the tethered photocatalyst.
Deazaflavin, Haloalkane is designed for use in photoproximity labeling experiments that aim to study protein interactions or spatial proteomics in live mammalian cells under mild illumination conditions without the use of metal-based photocatalysts.
