Fig. 7.

Representative diagram for the biosynthesis of occidiofungin. Some steps are demarcated with an asterisk, indicating the high potential of alternative routes of synthesis in the model. For instance, it is conceivable that glycosylation can occur before the synthesis of the peptide. In addition, no homology exists in the database for the proposed dehydratase activity of OcfB, and this activity may be attributed to another gene outside the gene cluster.
