UniProtKB accession:  O64989

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Catalyzes the C22-alpha-hydroxylation step in brassinosteroids biosynthesis (PubMed:9490746, PubMed:16460510). Converts campesterol (CR) to (22S)-22-hydroxycampesterol (22-OHCR, 22-hydroxyCR), campestanol (CN) to 6-deoxycathasterone (6-deoxoCT), and 6-oxocampestanol (6-oxoCN) to cathasterone (CT) (PubMed:9490746, PubMed:16460510). Can also use cholesterol and cholestanol as substrates (PubMed:9490746, PubMed:16460510).
