probing the determinants of coenzyme specificity in peptostreptococcus asaccharolyticus glutamate dehydrogenase by site-directed mutagenesis.	glutamate dehydrogenase (ec 1.4.1.2-4) from peptostreptococcus asaccharolyticus has a strong preference for nadh over nadph as a coenzyme, over 1000-fold in terms of kcat/km values. sequence alignments across the wider family of nad(p)-dependent dehydrogenases might suggest that this preference is mainly due to a negatively charged glutamate at position 243 (e243) in the adenine ribose-binding pocket. we have examined the possibility of altering coenzyme specificity of the peptostreptococcus enz ...	2007	17850332
