NCBI Protein Information
brassinosteroid-6-oxidase 2
NCBI Summary
Encodes a cytochrome p450 enzyme that catalyzes the last reaction in the production of brassinolide. It is capable of converting 6-deoxocastasterone into castasterone, a C-6 oxidation, as well as the further conversion of castasterone into brassinolide by a Baeyer-Villinger oxidation reaction at C-6, resulting in the formation of an unusual seven-membered lactone ring. The enzyme possesses high affinity for both C28- and C27-Brassinosteroids. The expression of the gene using a CYP85A2 promoter:LUC fusion construct was shown to be under circadian and light control.

UniProt Comments
Catalyzes the C6-oxidation step in brassinosteroids biosynthesis. Converts 6-deoxocastasterone to castasterone, and castasterone to brassinolide. May also convert 6-deoxoteasterone to teasterone, 3-dehydro-6-deoxoteasterone to 3-dehydroteasterone, and 6-deoxotyphasterol to typhasterol.
