The Discovery of Cofactorless Enzymes
Nestled within the extensive microbial natural product collection at The Herbert Wertheim UF Scripps Institute for Biomedical Innovation & Technology, a recent publication in Nature Chemical Biology brings attention to the discovery of two novel enzymes with unique properties. This breakthrough, led by chemist Dr. Ben Shen, carries potential applications in combating various human diseases, including cancer. Published last week, this discovery opens avenues for simplified approaches to studying and manufacturing intricate natural chemicals, some of which may evolve into pharmaceuticals, showcasing the intersection of Science, Industry, and Chemicals.
Transformative Role of TnmJ and TnmK2
The newly identified enzyme category, TnmJ and TnmK2, operates by drawing oxygen from the air and integrating it into novel compounds without relying on typical metals or other cofactors to initiate chemical reactions. This unique synthesis mechanism, driven by the enzymes, provides a survival advantage to the organisms by producing defensive substances, potentially aiding in fending off infections or invaders—a significant development at the intersection of Science and Industry.
Tiancimycin A: A Potential Antibiotic and Anticancer Compound
Postdoctoral researchers Dr. Chun Gui and Dr. Edward Kalkreuter highlight the immediate impact of these enzymes in unraveling the mystery behind the potency of a potential antibiotic and anticancer compound, tiancimycin A. The enzymes facilitate the production of compounds targeting and disrupting DNA, offering applications in viral defense, germ eradication, or cancer treatment. Tiancimycin A is currently undergoing development for cancer-targeting antibody therapy, marking an innovative approach in the chemical and pharmaceutical fields.
Exploring Nature’s Bounty: From Bacterial Strain Collection to Cofactorless Enzymes
The journey to understand tiancimycin A’s synthesis process led researchers to the institute’s Natural Products Discovery Center collection, comprising 125,000 bacterial strains. The discovery of cofactorless enzymes emerged from analyzing the genomes of tiancimycin A-like natural product-producing bacteria, unraveling evolutionary clues to their unique chemistry, thus integrating aspects of Chemical News into the study.
