title: The Klebsiella aerogenes glutamate dehydrogenase (gdhA) gene: cloning, high-level expression and hybrid enzyme formation in Escherichia coli.
abstract: The NADP-dependent glutamate dehydrogenase gene of Klebsiella aerogenes was cloned in E. coli in the expression plasmid pRK9. The cloned gene shows a high level of expression in E. coli in the hybrid plasmid pKG3 and such expression is independent of the vector promoter, as shown by experiments in which the promoter was deleted. Active hybrid GDH hexamers were shown in cell-free extracts of an E. coli strain carrying cloned gdhA genes of both E. coli and K. aerogenes. The nucleotide sequence of the N-terminal coding region of the K. aerogenes gdhA gene was determined and found to be strongly homologous with that of E. coli.
