Abstract

Heterologous expression of the tetranactin resistance gene nonR in E. coli gave a his6-tagged protein that catalyzed the stereoselective hydrolysis of the chiral macrotetrolide antibiotic nonactin into equivalent, chiral, inactive nonactate dimer species. No trimeric nonactate was produced in the reaction.
