The gene encoding an inorganic polyphosphate/ATP-
NAD kinase
was cloned from Micrococcus flavus, and its primary structure was analyzed. Alignment of the primary structure with those of other characterized NAD kinases revealed candidate amino acid residues, mainly charged ones, that would be related to inorganic polyphosphate use. The alignment also showed that the primary structure found carried a protruding C-terminal polypeptide. Although the C-terminal polypeptide was demonstrated to be dispensable for the kinase activities, and was proposed to be removed in M. flavus, the entire primary structure including the C-terminal polypeptide was homologous with that of the
ATP synthase
beta chain. The inorganic polyphosphate used by the inorganic polyphosphate/ATP-
NAD kinase
as a phosphoryl donor was isolated from cells of M. flavus, suggesting that the ability of the enzyme to use inorganic polyphosphate is of physiological significance and is not an evolutionary trait alone.
