Common Namescyllo-Inosose
Descriptionscyllo-Inosose is a cyclitol and a member of the carbohydrate chemical class. It is structurally characterized as a hexose derivative, specifically a tetrahydroxycyclohexanone, which plays a crucial role in various biochemical pathways. Scyllo-Inosose is involved in the biosynthesis of 2-deoxystreptamine-containing aminoglycoside antibiotics, such as kanamycin and neomycin, where it acts as an important precursor (PMID:33577648 ). The synthesis of 2-deoxy-scyllo-inosose (2-DOI) from d-glucose 6-phosphate is catalyzed by the enzyme 2-deoxy-scyllo-inosose synthase (DOIS) in producer microorganisms (PMID:33577648 ). Additionally, 2-deoxy-4-epi-scyllo-inosose (DEI), a derivative of scyllo-Inosose, is produced by the enzyme EboD in certain bacteria and algae, indicating its metabolic significance in diverse organisms (PMID:39404639 ). Furthermore, recombinant strains of Saccharomyces cerevisiae and Bacillus subtilis have been engineered to enhance the biosynthesis of 2-DOI, showcasing its potential applications in biotechnology (PMID:32670790 ; PMID:30319595 ). Overall, scyllo-Inosose and its derivatives are integral to various metabolic pathways, particularly in antibiotic biosynthesis.
