CpeY family
Description
CpeY was biochemically characterized as the lyase attaching PEB at Cys-82 alpha-PE (CpeA) from Fremyella diplosiphon strain UTEX 481. Its activity is enhanced by CpeZ. CpeY alone, but not CpeZ, can ligate PEB to CpeA, but with a reduced yield than CpeY and CpeZ together (Biswas et al. 2011). CpeY was also characterized in Synechococcus sp. RS9916 as a PEB:Cys-82 alpha-PEI in vitro in the presence or absence of CpeZ, but it was unable to attach PEB to Cys-83 alpha-PEII (Carrigee et al. 2020).
