Purification of Streptococcus group C bacteriophage lysin

Abstract

A simple procedure for the purification of Streptococcus group C phage lysin to apparent homogeneity is described. The electrophoretically pure, enzymatically stable polypeptide of 98,000 molecular weight converted Streptococcus (groups A, F, and H) cells into spheroplasts within 5 min at O°C or within less than a minute at 37°C.
