RT   "Complete sequence of Anabaena variabilis ATCC 29413.";
RL   Submitted (SEP-2005) to the EMBL/GenBank/DDBJ databases.
CC   -!- FUNCTION: Catalyzes the four-electron reduction of biliverdin IX-
CC       alpha (2-electron reduction at both the A and D rings); the
CC       reaction proceeds via an isolatable 2-electron intermediate,
CC       181,182-dihydrobiliverdin (By similarity).
CC   -!- CATALYTIC ACTIVITY: (3Z)-phycocyanobilin + oxidized ferredoxin =
CC       biliverdin IX-alpha + reduced ferredoxin.
CC   -!- SIMILARITY: Belongs to the HY2 family.
