the glutamate dehydrogenase catalyzed reduction of delta 1-pyrroline-2-carboxylic acid ( pca ; an alpha-imino acid ) with reduced nicotinamide adenine dinucleotide phosphate ( nadph ) to give l-proline and nadp+ is employed as a model for the redox step of the corresponding enzyme-catalyzed reductive amination of alpha-ketoglutarate .
