The role of leucine in isoprenoid metabolism. Incorporation of [3-13C]leucine and of [2-3H,4-14C]-β,β-dimethylacrylic acid into phytosterols by tissue cultures of Andrographis paniculata
Abstract
[3-13C]Leucine is incorporated into phytosterols by tissue cultures of Andrographis paniculata by breakdown to acetyl-CoA and its subsequent incorporation via(3S)-3-hydroxy-3-methylglutaryl-CoA(HMG-CoA) and mevalonic acid; [2-3H,4-14C]-β,β-dimethylacrylic acid also is not incorporated intact.
