The use of functional genomics for the identification of a gene cluster encoding for the biosynthesis of an antifungal tambjamine in the marine bacterium Pseudoalteromonas tunicata

A large insert library was created in Escherichia coli from the DNA of the surface-associated marine bacterium Pseudoalteromonas tunicata. Screening of the library for antifungal activity resulted in the detection and identification of a large gene cluster encoding for the biosynthesis of an antifungal tambjamine. A biosynthetic pathway has been proposed based on analysis and annotation of the gene cluster.
