Biotin cofactor
WebDec 9, 2016 · Organic cofactors are mainly derived from vitamins such as thiamine, riboflavin, biotin or niacin but there are also non-vitamin cofactors such as coenzyme Q 10 or heme. The group of inorganic cofactors comprises metal ions such as iron, magnesium, copper, zinc, and molybdenum. WebBiotin regulates the catabolic enzyme propionyl-CoA carboxylase at the posttranscriptional level whereas the holo-carboxylase synthetase is regulated at the transcriptional level. Biotin functions as a cofactor that …
