DESCRIPTION

Also known as CP125_MYCTU, cyp125, cyp125A1. Involved in the utilization of cholesterol as the sole carbon and energy source by degrading the side chain during infection (PubMed:20843794, PubMed:20545858). Primarily catalyzes the sequential oxidation of the terminal methyl of cholest-4-en-3-one into (25S)-26-hydroxycholest-4-en-3-one (alcohol), (25S)-26-oxocholest-4-en-3-one (aldehyde), to finally yield the carboxylic acid (25S)-3-oxocholest-4-en-26-oate (PubMed:19846551, PubMed:20843794, PubMed:20545858). Also able to sequentially oxidize cholesterol itself, not only cholest-4-en-3-one (PubMed:19846551, PubMed:20843794, PubMed:20545858).
