ENZYME entry: EC 1.21.3.3

Accepted Name
reticuline oxidase
Alternative Name(s)
berberine bridge enzyme
berberine-bridge-forming enzyme
tetrahydroprotoberberine synthase
Reaction catalysed
(S)-reticuline + O2 = (S)-scoulerine + H(+) + H2O2
Comment(s)
  • Acts on (S)-reticuline and related compounds, converting the N-methyl group into the methylene bridge ('berberine bridge') of (S)- tetrahydroprotoberberines.
  • The product of the reaction, (S)-scoulerine, is a precursor of protopine, protoberberine and benzophenanthridine alkaloid biosynthesis in plants.
  • Formerly EC 1.5.3.9.
