bacteriocin fulvocin C-related protein Fulvocin C was described in 1981 as a bacteriocin from Myxococcus fulvus, 45 amino acids long with 8 cysteines. The precursor form was not described. However, the most closely related precursor-like proteins represent the founding members of a family of proteins that average over 225 amino acids in length, the majority of which have a C-terminal tail region in which the 8 Cys residues are essentially invariant. The long N-terminal region, and the sharp change in amino acid composition at the start of what appears to be the bacteriocin core peptide region, suggests that the N-terminal region may contribute directly in peptide maturation or transport, rather than merely providing for recognition by maturation proteins. |
