Localization of two L-glutamate dehydrogenases in the coral Acropora latistella.

The coral Acropora latistella has been shown to contain two distinct L-glutamate dehydrogenases. An NADPH-specific GDH, closely resembling the enzyme from other coelenterates, is located in the cytosol; a distinct NADH-specific GDH is localized within the mitochondria. This is in contrast to earlier reports, where the NADPH-specific enzyme was thought to be the only GDH present and was assumed to be mitochondrial. Preliminary kinetic and stability data are presented for the two GDHs.
