Toward Understanding the Chemistry and Biology of 1-Deoxy-d-xylulose 5-Phosphate (DXP) Synthase: A Unique Antimicrobial Target at the Heart of Bacterial Metabolism
2018
ConspectusAntibiotics are the cornerstone of modern healthcare. The 20th century discovery of sulfonamides and β-lactam antibiotics altered human society immensely. Simple bacterial infections were no longer a leading cause of morbidity and mortality, and antibiotic prophylaxis greatly reduced the risk of infection from surgery. The current healthcare system requires effective antibiotics to function. However, antibiotic-resistant infections are becoming increasingly prevalent, threatening the emergence of a postantibiotic era. To prevent this public health crisis, antibiotics with novel modes of action are needed. Currently available antibiotics target just a few cellular processes to exert their activity: DNA, RNA, protein, and cell wall biosynthesis. Bacterial central metabolism is underexploited, offering a wealth of potential new targets that can be pursued toward expanding the armamentarium against microbial infections.Discovered in 1997 as the first enzyme in the methylerythritol phosphate (MEP) pa...
