WebFatty acid synthesis is probably driven by a plastid-localized ‘prokaryotic’ ACCase that includes biotin carboxylase, biotin carboxyl carrier protein, and two carboxyltransferase subunits. Of the plastid ACCase subunits, three are believed to be encoded in the nucleus, while the gene for a fourth has been identified in the chloroplast genome. WebThis enzyme is stimulated by high levels of acetyl-CoA (produced in β-oxidation in the liver) and inhibited by high levels of ADP and glucose. Oxaloacetate is reduced to malate using NADH, a step required for its transportation out of the mitochondria. fax console windows vista
