CC   -!- FUNCTION: Catalyzes the four-electron reduction of biliverdin IX-alpha
CC       (2-electron reduction at both the A and D rings); the reaction proceeds
CC       via an isolatable 2-electron intermediate, 181,182-dihydrobiliverdin.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=(2R,3Z)-phycocyanobilin + 4 oxidized [2Fe-2S]-[ferredoxin] =
CC         biliverdin IXalpha + 4 H(+) + 4 reduced [2Fe-2S]-[ferredoxin];
