rho and g22k appeared to be different proteins since ( i ) rho migrated faster on polyacrylamide gels , ( ii ) unlike g22k , rho did not require the presence of cytosol to be adp-ribosylated , ( iii ) g22k was not recognized by an anti-rho antiserum , and ( iv ) antibody 142-24e05 recognized g22k effectively but only poorly cross reacted with rho .
