The primary structure of fulvocin C from Myxococcus fulvus
Biochimica Et Biophysica Acta
|January 30, 1981
Abstract:
The primary structure of fulvocin C, a bacteriocin produced by Myxococcus fulvus strain Mx f16, has been determined. This new bactericidal protein is composed of 45 amino acid residues and has a molecular weight of 4672. It contains no lipids or carbohydrates, indicating that only the protein molecule is responsible for its biological activity.
Insights
The primary structure of fulvocin C, a novel bacteriocin from Myxococcus fulvus, was identified. This 45-amino acid protein is responsible for its own potent bactericidal activity.
