Vancomycin is a tricyclic glycopeptide antibiotic derived from Amycolatopsis orientalis (formerly Nocardia orientalis) used for serious gram positive infections.
INTRODUCTION: Vancomycin, a tricyclic glycopeptide antibiotic (C66H75C12N9024) first isolated from a soil bacterium Actinobacteria species Amycolatopsis orientalis, acts by inhibiting the formation of the peptidoglycan polymers of the bacterial cell wall.
In the vancomycin producer Amycolatopsis orientalis C329.2, homologs of these genes are present, suggesting an origin for the cluster.
