ENZYME entry: EC 4.4.1.30

Accepted Name
Phycobiliprotein beta-cysteine-155 phycobilin lyase.
Reaction catalysed
  • [C-phycocyanin beta-subunit]-Cys(155)-phycocyanobilin <=> apo-[C-phycocyanin beta-subunit] + (2R,3E)-phycocyanobilin
  • [Phycoerythrocyanin beta-subunit]-Cys(155)-phycocyanobilin <=> apo-[phycoerythrocyanin beta-subunit] + (2R,3E)-phycocyanobilin
Comment(s)
  • The enzyme, found in cyanobacteria and red algae, catalyzes the attachment of the phycobilin chromophore phycocyanobilin to cysteine 155 of the beta subunits of the phycobiliproteins C-phycocyanin and phycoerythrocyanin.
  • The numbering used here corresponds to the enzyme from Anabaena, and could vary slightly in other organisms.
