Cloning, expression, and biological function of a dTDP-deoxyglucose epimerase (gerF) gene from Streptomyces sp. GERI-155.

GERI-155 is a macrolide antibiotic containing two deoxyhexose molecules which has antimicrobial activities against gram-positive bacteria. The deoxyhexose biosynthetic gene cluster of GERI-155 from Streptomyces sp. GERI-155 genome has now been isolated.
