Figure 1 shows that Pic inhibits all three complement cascades, as shown by the decrease in deposition of C4b with anti-C4 antibodies. Figure 2 shows that Pic cleaves complement proteins. Figure 3 shows that Pic present in the supernatant of E.coli is also able to cleave purified complement proteins. Figure 4 shows that it cleaves complement proteins found in human serum
