CA_C0660 family putative sactipeptide bacteriocin Members of this family are Cys-rich peptides about 65 amino acids in length, regularly found in the vicinity of the radical SAM/SPASM domain enzymes. The most closely related such radical SAM enzyme is the RiPP modification enzyme that introduces sulfur-to-alpha-carbon peptide (sactipeptide) modification in ruminococcin C, whose precursor is very similar in length and in Cys content and arrangement.
