CpeZ family
Description
CpeZ enhances the activity of CpeY. CpeYZ is involved in the attachment of PEB at Cys-82 alpha-PE (CpeA). CpeY alone, but not CpeZ can ligate PEB to CpeA, but with a reduced yield than CpeY and CpeZ together (Biswas et al., 2011). More recently Kronfel et al. (2019) showed that CpeZ acts as a chaperone-like protein, assisting in the folding/stability of PE subunits, allowing bilin lyases such as CpeY and CpeS to attach PEB to their PE subunit.
