L amino acid dehydrogenases in Bacillus subtilis spores

Abstract

The presence of two kinds of L amino acid dehydrogenase in resting spores of Bacillus subtilis was indicated. One of them was L alanine dehydrogenase, which used only L alanine as a substrate, and the other was nonspecific dehydrogenase, which used L valine, L isoleucine, L leucine, and L alanine (slightly) as substrates. Several properties of these dehydrogenases were compared.
