analyses of subunit proteins by sds-polyacrylamide slab gel electrophoresis showed that these pyocins were composed of 5 major ( bands 1 , 2 , 3 , 4 , and 6 ) and 2 minor ( bands 5 and 7 ) subunit proteins and that no difference in the mobilities of these subunit proteins could be detected among the pyocins except that of the second major subunit protein ( band 4 ) , which did differ .
