This is a family of 2-dehydropantoate 2-reductases also known as ketopantoate reductases, EC:1.1.1.169. The reaction catalysed by this enzyme is: (R)-pantoate + NADP(+) <=> 2-dehydropantoate + NADPH. AbpA catalyses the NADPH reduction of ketopantoic acid to pantoic acid in the alternative pyrimidine biosynthetic (APB) pathway [2]. ApbA and PanE are allelic [2]. ApbA, the ketopantoate reductase enzyme is required for the synthesis of thiamine via the APB biosynthetic pathway [1].	Domain
