The enzyme activities of four strains of Legionella pneumophilia were investigated by using the API ZYM system (API System S.A., F-38390 Montalieu Vercieu, France) and synthetic substrates. Aminopeptidases were detected specifically against L-alanine, L-arginine, L-aspartic acid, L-cystine, L-glutaminic acid, glycine, L-histidine, L-isoleucine, L-leucine, L-lysine, L-methionine, L-phenylalanine, L-tryptophan, L-tyrosine, and L-valine. Furthermore, the bacteria possesses esterase activity splitting propionate, butyrate, caproate, caprylate, and caprate, but not laurate, myristate, palmitate, and stearate, esters. The enzymes studies were inhibited partially by aprotinin. No inhibition of phosphatase (pH range, 5.4 to 8.5) or of phosphoamidase was observed. Activities of arylsulfatase, chymotrypsin, trypsin, and glycosidases could not be detected.

The enzyme spectrum of non proliferating cells of Erysipelothrix rhusiopathiae was investigated by means of different low molecular synthetic substrates. Activities of aminopeptidases were found directed against compounds of L-alanine, L-arginine, L-aspartic acid, glycine, L-isoleucine, L-leucine, L-lysine, L-methionine, L-phenylalanine, L-proline, L-tryptophane, and L-tyrosine, but not against compounds of l-cystine, L-glutaminic acid, L-histidine, L-hydroxyproline, and L-valine (Table 1). The pH optimum of the investigated aminopeptidases ranges from neutral to alkaline reaction (Table 2). Trypsin, chymotrypsin, or chymotrypsin-like proteases were not detected. E. rhusiopathiae possess esterase activity splitting esters of lower carboxylic acids, i. e. acetic acid, propionic acid, butyric acid, caproic acid, and caprylic acid, but no lipase activity. Under the provoked glycosidases only alpha- and beta-D-galactosidase and glucosaminidase were positive. Weak activities of phosphatases and arylsulfatase were found also (Table 3).
