RESUMO
Selenomonas ruminantium, a strictly anaerobic, gram-negative bacterium isolated from sheep rumen, contains lysine decarboxylase (Y. Kamio et al., J. Bacteriol. 145:122-128, 1981). This report describes the synthesis, purification, and characterization of the enzyme. Lysine decarboxylase was synthesized in cells grown in chemically defined medium without lysine. The enzyme was purified approximately 1,800-fold to electrophoretic homogeneity. The native enzyme of approximate molecular weight 88,000 consisted of two identical subunits, each with a molecular weight of 44,000. Several properties of the enzyme were determined and compared with those of the lysine decarboxylases from Escherichia coli and Bacterium cadaverisis.
