Transaminase Mechanism (Pyruvate Conversion to L-Alanine)

The video tutorial explains the mechanism of alanine transaminase, focusing on its role in the biosynthesis of alanine. It details the catalytic components, including pyridoxal phosphate and lysine, and describes the transamination reaction mechanism. The formation of the quinonoid intermediate and the concept of an electron sink are highlighted. The tutorial concludes with the final steps of the mechanism and the regeneration of pyridoxal phosphate.

Explain the process of nucleophilic attack in the transaminase mechanism.

Discuss the concept of an electron sink in the context of pyridoxal phosphate.

What is the role of water in the transaminase mechanism?

What are the final products of the transaminase reaction when starting with pyruvate and L-glutamate?
