the enzyme previously considered as an isozyme ( e4 , aldh iv ) of human liver aldehyde dehydrogenase ( nad+ ) ( ec 1.2.1.3 ) has been purified to homogeneity by the use of ion exchange chromatography on cm-sephadex and affinity chromatography on blue sepharose cl-6b and 5'-amp sepharose 4b and identified as glutamic gamma-semialdehyde dehydrogenase , or more precisely 1-pyrroline-5-carboxylate dehydrogenase ( ec 1.5.1.12 ) .
