The glucosamine-6-phosphate riboswitch ribozyme ( glmS ribozyme) is an RNA structure that resides in the 5' untranslated region (UTR) of the mRNA transcript of the glmS gene. This RNA regulates the glmS gene by responding to concentrations of a specific metabolite, glucosamine-6-phosphate … See more The structure of the glmS ribozyme was first determined by X-ray crystallography in 2006. The tertiary structure of this RNA is characterized by three coaxial stacked helices, packed side by side. The ribozyme core … See more Although glmS ribozyme performs self-cleavage upon binding GlcN6P, the glmS ribozyme active site does not undergo conformational change upon binding GlcN6P. Instead, the active site is pre-formed and glmS ribozyme activity is triggered by the … See more • Riboswitch See more • Page for glmS glucosamine-6-phosphate activated ribozyme at Rfam See more Web开馆时间：周一至周日7:00-22:30 周五 7:00-12:00; 我的图书馆

Article CAS PubMed Google Scholar WebThe glmS ribozyme is a catalytic riboswitch that is activated for endonucleolytic cleavage by the coenzyme glucosamine-6-phosphate. Using kinetic assays and X-ray crystallography, we identify an active-site mutation of a conserved guanine that abolishes catalysis without perturbing coenzyme binding. Our results provide evidence that coenzyme function …
WebDec 12, 2014 · The glmS riboswitch is unique among gene-regulating riboswitches and catalytic RNAs. This is because its own metabolite, glucosamine-6-phosphate (GlcN6P), binds to the riboswitch and catalytically participates in the RNA self-cleavage reaction, thereby providing a novel negative feedback mechanism. Given that a number of …
