Common Name | Campest-4-en-3-one |
---|
Description | Campest-4-en-3-one is an intermediate in Brassinolide Biosynthesis pathway.The conversion of the membrane Sterol Campesterol to BL occurs via a series of reductions, hydroxylations, epimerizations and oxidations that have been extensively studied in several species. The conversion of Campesterol to Campestanol is not a single step, but composed of the biosynthetic sequence of Campesterol 4-en-3Beta-ol ---> 4-en-3-one ---> 3-one ---> Campestanol in Arabidopsis. In the first step, Campesterol is converted to Campest-4-en-3Beta-ol in presence of enzyme Delta-5-3-Ketosteroid Isomerase. Enzymes that catalyze the conversion from 3-Beta-Hydroxy-Delta,5-6-Steroid to 3-oxo-Delta-4-5 Isomerase have been reported in Bacteria and Mammals. Campest-4-en-3 Beta-ol is converted to Campest-4-en-3-one in presence of enzyme 3-Beta-Hydroxysteroid Dehydrogenase. In the next step, Campest-4-en-3-one is converted to Campestanol via 5-Alpha-Campestan-3-one. 3-Oxo-5Alpha-Steroid 4-Dehydrogenase family members (encoded by Det2 in Arabidopsis) catalyze the formation of 5-Alpha-Campestan-3-one. |
