ABSTRACT:
A DNA fragment containing acyB gene coding for an enzyme capable of acylating the 4"-position of a macrolide antibiotic, said DNA fragment being derived from a microorganism of the genus Streptomyces, having a size of about 3.1 kb and being characterized by the restriction endonuclease map shown in FIG. 1 , and a DNA restriction fragment resulting from digestion with a restriction endonuclease; a recombinant DNA plasmid containing this DNA fragment; a microorganism transformed with this recombinant plasmid; and a process for producing a 4"-acylated macrolide antibiotic by using the transformant.
