WebApr 11, 2024 · Biotin acts as a prosthetic group for this enzyme. Biotin acts as a carrier of a one-carbon group in its oxidized state. Biotin is an essential part of the human diet and is abundant in many food sources. Reaction Steps-There are the following steps in which pyruvate carboxylase catalyzes the reaction.
Webreaction. The enzyme has biotin as a prosthetic group, and we will discuss the mechanism of this enzyme in more detail next term in connection with other biotin carboxylases. PEP carboxykinase probably more important in working in reverse to form phosphoenolpyruvate. Slide 21 Pyruvate Carboxylase • Contains biotin prosthetic group. WebThe first committed step in fatty acid biosynthesis is catalysed by acetyl-CoA carboxylase (EC 6.4.1.2). This belongs to the group of soluble Class 1 biotin-containing enzymes which use ATP and bicarbonate to carboxylate a biotin prosthetic group (Fig. 2). The carboxy group is then transferred to the acceptor acetyl-CoA to form malonyl-CoA.
