The biosynthetic gene cluster for the polyene antifungal antibiotic, 20-O-methylmyxalamide D, was cloned from myxobacterium Cystobacter fuscus AJ-13278. A sequence analysis of the 12.8-kb region in the gene cluster revealed the presence of two type I polyketide synthase genes, mmxB and mmxC. The involvement of these two genes in the biosynthesis of 20-O-methylmyxalamide D was confirmed by a gen...

Cruentaren A, an antifungal benzolactone produced by the myxobacterium Byssovorax cruenta, is highly cytotoxic against various human cancer cell lines and a highly selective inhibitor of mitochondrial F-ATPase. A convergent and efficient synthesis of cruentaren A is reported, based upon a diastereoselective alkylation, a series of stereoselective aldol reactions utilizing Myers' pseudoephedrine...

Antibiotic TA is a macrocyclic secondary metabolite produced by myxobacteria that has broad-spectrum bactericidal activity. The structure of TA is unique, and its molecular target is unknown. Here, we sought to elucidate TA's mode of action (MOA) through two parallel genetic approaches. First, chromosomal Escherichia coli TA-resistant mutants were isolated. One mutant that showed specific resis...
