AM1_C0023g2 Ser334Gly mutant
Protein DomainAM1_C0023g2 Ser334Gly mutant is a cyanobacteriochrome-derived protein domain variant in which Ser334 is replaced by Gly. It retains the AM1_C0023g2 scaffold’s covalent bilin-binding and light-dependent photoconversion properties, and the mutation was reported to significantly improve the yield of the biliverdin-binding holoprotein, supporting its use as a platform for future optogenetic switch development.
