X-RAY STRUCTURE OF THE BIFUNCTIONAL 6-HYDROXYMETHYL-7,8-DIHYDROXYPTERIN PYROPHOSPHOKINASE DIHYDROPTEROATE SYNTHASE FROM SACCHAROMYCES CEREVISIAE
OverviewOverview
In Saccharomyces cerevisiae and other fungi, the enzymes dihydroneopterin, aldolase, 6-hydroxymethyl-7,8-dihydropterin pyrophosphokinase (HPPK) and, dihydropteroate synthase (DHPS) are encoded by a polycistronic gene that, is translated into a single polypeptide having all three functions. These, enzymatic functions are essential to both prokaryotes and lower, eukaryotes, and catalyse sequential reactions in folate biosynthesis., Deletion or disruption of either function leads to cell death. These, enzymes are absent from mammals and thus make ideal antimicrobial targets., DHPS is currently the target of antifolate therapy for a number of, infectious diseases, and its activity is inhibited by sulfonamides and, sulfones. These drugs are typically used as part of a synergistic cocktail, ... [(full description)]
