>TIGR00745 apbA_panE 2-dehydropantoate 2-reductase; InterPro: IPR003710 ApbA, the ketopantoate reductase enzyme 1.1.1.169 from EC of Salmonella typhimurium is required for the synthesis of thiamine via the alternative pyrimidine biosynthetic pathway . Precursors to the pyrimidine moiety of thiamine are synthesized de novo by the purine biosynthetic pathway or the alternative pyrimidine biosynthetic (APB) pathway. The ApbA protein catalyzes the NADPH-specific reduction of ketopantoic acid to pantoic acid. This activity had previously been associated with the pantothenate biosynthetic gene panE . ApbA and PanE are allelic .; GO: 0008677 2-dehydropantoate 2-reductase activity, 0006206 pyrimidine base metabolic process.
