Immunodetection of HpaG mutant proteins. Production of the mutant proteins was induced with IPTG induction. After boiling and purification procedures, the proteins were analyzed by immunoblotting with a rabbit polyclonal anti-HpaG antibody. (A) Immunodetection of full-length HpaG mutants. Lanes: 1, pET14b vector control; 2, HpaG; 3, HpaG(L39A); 4, HpaG(L39P); 5, HpaG(L42D); 6, HpaG(L43P); 7, HpaG(Q45A); 8, HpaG(L46A); 9, HpaG(L50A); 10, HpaG(L50P); 11, HpaG(L43P/L50P). (B) Immunodetection of HpaG deletion mutants. Lanes: 1, pET14b vector control; 2, HpaGΔC66; 3, HpaGΔC75; 4, HpaGΔC77; 5, HpaGΔC79; 6, HpaGΔC81; 7, HpaGΔC83; 8, HpaGΔN67.
