4.4.1.31 | apo-[phycoerythrocyanin alpha-subunit PecA] + phycocyanobilin |
substrate PecA and subunit PecE form a weak complex that is stabilized by phycocyanobilin. The first reaction step involves a conformational change and/or protonation of phycocyanobilin, and subunit PecE has a chaperone-like function on the chromoprotein |
