6.2.1.42	physiological function	the enzyme encoded by gene fadD19 plays a role in the degradation process of the side chain of cholesterol and beta-sitosterol, but is not essential for viability. FadD19 is required in the initial step of the biodegradation of C-24 branched sterol side chains in Mycobacterium smegmatis mc2155, like beta-sitosterol, but not those carrying a straight chain, like cholesterol. The enzyme has an essential role of FadD19 in the early step of beta-sitosterol degradation	-, 745820
