C90C1_ARATH | function | Involved in brassinosteroid (BR) biosynthesis (PubMed:15703058, PubMed:17138693). Converts typhasterol (TY) to cathasterone (CS) and 6-deoxotyphasterol (6-deoxoTY) to 6-deoxocathasterone (6-deoxoCT) (PubMed:15703058). C-23 hydroxylase that converts directly (22S,24R)-22-hydroxy-5-alpha-ergostan-3-one and 3-epi-6-deoxocathasterone to 3-dehydro-6-deoxoteasterone (6-deoxo3DT, 6-deoxo3DHT) and 6-deoxotyphasterol (6-deoxoTY), respectively (PubMed:17138693). These C-23 hydroxylation shortcuts bypass campestanol, 6-deoxocathasterone, and 6-deoxoteasterone (6-deoxoTE) (PubMed:17138693). Catalyzes also the conversion of cathasterone to teasterone (TE), (22S,24R)-22-hydroxyergost-4-en-3-one (22-OH-4-en-3-one) to (22R,23R)-22,23-dihydroxy-campest-4-en-3-one (22,23-diOH-4-en-3-one) and (22S)-22-hydroxycampesterol (22-OHCR) to (22R,23R)-22,23-dihydroxycampesterol (22,23-diOHCR) (PubMed:17138693). Required for the regulation of polar elongation of leaf cells (PubMed:10430960, PubMed:9694802). Required for the longitudinal elongation of floral organs (PubMed:10430960). |
