Comments
  • FUNCTION: Catalyzes the four-electron reduction of biliverdin IX-alpha (2-electron reduction at both the A and D rings); the reaction proceeds via an isolatable 2-electron intermediate, 181,182-dihydrobiliverdin (By similarity).
  • CATALYTIC ACTIVITY: (3Z)-phycocyanobilin + oxidized ferredoxin = biliverdin IX-alpha + reduced ferredoxin.
  • SIMILARITY: Belongs to the HY2 family.
