Chromophore attachment to phycobiliprotein beta-subunits: phycocyanobilin:cysteine-beta84 phycobiliprotein lyase activity of CpeS-like protein from Anabaena Sp. PCC7120.

Abstract excerpt

The gene alr0617, from the cyanobacterium Anabaena sp. PCC7120, which is homologous to cpeS from Gloeobacter violaceus PCC 7421, Fremyella diplosiphon (Calothrix PCC7601), and Synechococcus sp. WH8102, and to cpcS from Synechococcus sp. PCC7002, was overexpressed in Escherichia coli. CpeS acts as a phycocyanobilin: Cys-beta84-phycobiliprotein lyase that can attach, in vitro and in vivo, phycocyanobilin (PCB) to...
