[NAD-dependent N-methylglutamate dehydrogenase--new enzyme metabolizing methylamine in methylotrophs].

The properties of N-methylglutamate dehydrogenase, a new enzyme of methylamine metabolism in a facultative methylotroph Pseudomonas methylica, strain 2, were investigated. The enzyme was strictly dependent on the NAD presence and was not connected with particles in cell-free preparations. The enzyme appeared to be incucible and its activity increased after the growth of the cells in a medium containing methylamine.
