Hemoglobin, its chains, and myoglobin enhance the antibiotic activity of colicine K. These proteins also interact with colicine K and other O antigens to alter their serological activity. The hemoglobin proteins did not alter the serological activities of three Pneumococcus polysaccharides or T4 bacteriophage DNA antigens but did alter the antigenic activity of fetuin. Interaction of hemoglobin and colicine K resulted in a retardation of colicine K antibiotic moiety as measured by gel filtration but did not affect the gel filtration properties of the lipopolysaccharide moiety.
血红蛋白、其亚基以及肌红蛋白可增强大肠杆菌素K的抗菌活性。这些蛋白质还与大肠杆菌素K及其他O抗原相互作用,从而改变它们的血清学活性。血红蛋白类蛋白质不会改变三种肺炎球菌多糖或T4噬菌体DNA抗原的血清学活性,但会改变胎球蛋白的抗原活性。通过凝胶过滤测定发现,血红蛋白与大肠杆菌素K的相互作用会导致大肠杆菌素K抗菌部分的滞留,但不影响脂多糖部分的凝胶过滤特性。
