Endopeptidase So (EC 3.4.21.67, E. coli cytoplasmic proteinase, proteinase So, Escherichia coli serine proteinase So) is an enzyme.[1][2] This enzyme catalyses the following chemical reaction

Hydrolysis of proteins, but not Bz-Tyr-OEt, Ac-Phe-beta-naphthylester, or Bz-Arg-OEt

This is an Escherichia coli cytoplasmic endopeptidase.
