Hydrolysis of nitrocefin by M. tuberculosis PBPs in the presence of β-lactams. The percentages of nitrocefin hydrolyzed by unit PBP in the presence of unit β-lactam under identical reaction conditions are shown. Nitrocefin hydrolyzed in the absence of β-lactam is considered 100% (control), and the amounts of nitrocefin hydrolyzed in the presence of β-lactam are represented in comparison to the control. Additional details are included in Fig. S2.
