Abstract

Aspartokinase activity was regulated by feedback inhibition in members of the genus . In five species the enzyme was inhibited by -threonine and by -lysine. The sensitivity of the enzyme to -threonine was much higher than its sensitivity to -lysine. Aspartokinase was also subject to concerted feedback inhibition by low concentrations of both of these amino acids. Six strains of and possessed a similar regulation pattern, which differed from that found in and . The taxonomic value of the pattern of inhibition of aspartokinase in the genus and its relation to other genera is discussed.
