Figure 2. Specificity testing of the 3xGly substrate.

Culture supernatants of Pseudomonas spp., respiratory microorganisms and bacteria producing lysostaphin (*) or lysostaphin-like (**) proteases were incubated with 16 µM 3xGly. Fluorescence was measured for 1 h at 37 °C. Results are expressed as mean ± SEM (n = 3).
