show Brenda entry

EC number

1.21.3.5

Accepted name

sulochrin oxidase [(-)-bisdechlorogeodin-forming]

Reaction

2 sulochrin + O₂ = 2 (-)-bisdechlorogeodin + 2 H₂O

Other name(s)

sulochrin oxidase

Systematic name

sulochrin:oxygen oxidoreductase (cyclizing, (-)-specific)

CAS registry number

82469-87-2

Comment

Also acts on several diphenols and phenylenediamines, but has low affinity for these substrates. Involved in the biosynthesis of mould metabolites related to the antibiotic griseofulvin.
