The glutamate dehydrogenase system is examined in different Neisseria species. The pH optima, temperature sensitivity, and the effect upon enzyme activity by adding glucose to the medium are compared to the findings in N. meningitidis. By agar gel electrophoresis it is shown that all species except N. catarrhalis, N. ovis and N. caviae contain 2 different glutamate dehydrogenases, one linked to NAD and the other one to NADP. The 3 species mentioned possibly contain only one glutamate dehydrogenase, reacting with both coenzymes. The taxonomic implications of these findings are discussed.
