The pSKC2 cosmid, which has 32 kb and 28 open-reading frames, was isolated from Streptomyces kanamyceticus ATCC12853 as the gene cluster of kanamycin. This gene cluster includes the minimal biosynthetic genes of kanamycin with the resistance and regulatory genes. It was heterologously expressed in Streptomyces venezuelae YJ003, which has the advantage of fast growth, good efficiency of the transformation host, and rapid production of the aminoglycosides antibiotic. The isolated compound was analyzed by electrospray ionization-mass spectrometry, liquid chromatography-mass spectrometry, high-performance liquid chromatography, and tandem mass spectrometry and shows a molecular weight of 485 as kanamycin A.
