Fig. 1From: A novel aminotransferase gene and its regulator acquired in Saccharomyces by a horizontal gene transfer eventDialkylglycine decarboxylase reaction. The aminotransferase catalyzes the AIB through two half-reactions. The first step corresponds to AIB decarboxylation releasing CO2. The second, to the transamination of the amino group of the intermediate PMP to the pyruvate that produces L-alanine [13, 14]Back to article page
