CyanoLyase

CpeU family

Description

No member of this putative phycobilin lyase has been fully biochemically characterized yet. Given its gene environment (see e.g. Grébert et al. 2022), this is probably a PEB:PEI lyase, but the cysteinyl residue chromophorylated by this enzyme is unknown yet. In marine Synechococcus pigment type 3 strains, it may also act on the corresponding site of PEII, at least in low-PUB strains.
