Figure 1. Comparison of the van gene cluster from the glycopeptide producer Streptomyces toyocaensis (32) and of the vanA operon (33) from gram-positive cocci. Open arrows represent coding sequences and indicate direction of transcription. The guanosine plus cytosine content (% GC) is indicated in the arrows. The percentage of amino acid (aa) identity between the deduced proteins is indicated under the arrows.
