SDS-PAGE analysis of purified protein. Shown are the Carocin S3K (a) and Carocin S3I (b). Samples were subjected to electrophoresis in 10% polyacrylamide gels, which were stained with Coomassie blue. These were labeled as follows: lane M, molecular weight standards (kDa); lane 1, cell lysate of E. coli BL21/pET32a; lanes 2 and 4, IPTG-induced cell lysates of BL21/pES3kI and BL21/pES3I, respectively; lanes 3 and 5, a purified protein obtained after elution. The arrowheads indicate the killing protein of Carocin S3K (a) and the immunity protein of Carocin S3I (b)
