CyanoLyase

CpeS-ProHL subfamily

Description

This subfamily contains only the sequences of Prochlorococcus marinus HL ecotypes. CpeS sequence is the sole phycobilin lyase present in these genomes and was biochemically characterized in strain MED4 as a PEB:Cys-82 beta-PEIII (PpeB) lyase (Wiethaus et al., 2010). PpeB is also the sole PBP present in this (and other Prochlorococcus HL) strain.
