EC 1.3.7.2 Details

show Brenda entry

EC number

1.3.7.2

Accepted name

15,16-dihydrobiliverdin:ferredoxin oxidoreductase

Reaction

15,16-dihydrobiliverdin + oxidized ferredoxin = biliverdin IXα + reduced ferredoxin

Other name(s)

PebA

Systematic name

15,16-dihydrobiliverdin:ferredoxin oxidoreductase

CAS registry number

347401-20-1

Comment

Catalyses the two-electron reduction of biliverdin IXα at the C15 methine bridge. It has been proposed that this enzyme and EC 1.3.7.3, phycoerythrobilin:ferredoxin oxidoreductase, function as a dual enzyme complex in the conversion of biliverdin IXα into phycoerythrobilin.
