WebAug 1, 2008 · PC (pyruvate carboxylase) is a biotin-containing enzyme that catalyses the HCO (3) (-)- and MgATP-dependent carboxylation of pyruvate to form oxaloacetate. This is a very important anaplerotic reaction, replenishing oxaloacetate withdrawn from the tricarboxylic acid cycle for various pivotal biochemical pathways. WebBiotinidase deficiency is an inherited disorder in which the body is unable to recycle the vitamin biotin. The more severe form of the disorder is called 'profound Biotinidase deficiency' and may cause delayed development, seizures, weak muscle tone (hypotonia), breathing problems, hearing and vision loss, problems with movement and balance …
