Alanine aminotransferase 2, also known as GPT2, catalyzes the reversible transamination between alanine and 2-oxoglutarate to form pyruvate and glutamate. Subsequently, they play a key role in the intermediary metabolism of glucose and amino acids. GPT2 expression is high in muscle, fat and kidney. Recombinant human GPT2 protein, fused to His-Tag at N-terminal, was expressed in E. coli and purified by using conventional chromatography techniques. Source: Recombinant protein corresponding to aa1-523 from human ALT2, fused to His-Tag at C-terminal, expressed in E.coli.
