FIG. 6.
Profile of PG fragments released from gonococci during growth. The PG of strains JD1616 [atlA(E48A)] and MS11 (wild type) was 3H labeled, and then strains were grown without label. Culture supernatants were collected, and released 3H-labeled PG fragments were separated by gel filtration. The percentage of radioactivity in each fraction per total radioactivity eluted was plotted over time. Wild-type gonococci and gonococci with an alteration in the putative active site of AtlA did not differ in their profiles of released PG fragments during growth.
