Single-Stage Bioconversion of Phytosterol into Testosterone by Recombinant Strains of Mycolicibacterium neoaurum
Abstract
A plasmid containing the genes encoding a fungal 17β-hydroxysteroid dehydrogenase, which ca-talyzes the reduction of 17-oxo group, and a mycobacterial glucose-6-phosphate dehydrogenase, which promotes the recycling of the essential coenzyme NAD(P)H, was constructed. Its constitutive expression in well-studied Mycolicibacterium neoaurum strains made it possible to increase the yield of C-17 hydroxysteroids significantly. In particular, recombinant strains created on the basis of M. neoaurum VKM Ac-1815D and M. neoaurum NRRL B-3805 ΔkstD exhibited predominant accumulation of testosterone, while the strain based on M. neoaurum VKM Ac-1816D accumulated 1(2)-dehydrotestosterone and testosterone simultaneously.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
