研究结论

Date Results Publications
2018-11-17 11:38:00 Glucose preference over another phosphoenolpyruvate:sugar phosphotransferase system (PTS) sugar, mannitol, is absolutely dependent on the general PTS component HPr, but not on EIIAGlc, in E. coli. Dephosphorylated HPr accumulates during the transport of glucose and interacts with the mannitol operon regulator, MtlR, to augment its repressor activity. 28225088
2017-09-16 11:51:00 HPr is either phosphorylated on a histidyl residue (HPr-P) or non-phosphorylated (HPr). Data suggest HPr (the non-phosphorylated form) participates in allosteric regulation of the activities of pyruvate kinase (PykF, but not PykA), phosphofructokinase (PfkB, but not PfkA), glucosamine-6-phosphate deaminase (NagB), and adenylate kinase (Adk). 28634232
2017-06-24 10:31:00 Results suggest that the phosphoenolpyruvate hexose phosphotransferases PTS network serves as a global sensor of the sugar influx and also monitors the levels of several non-PTS compounds. 27557415
2014-03-01 12:15:00 HPr antagonizes the anti-sigma70 activity of Rsd in Escherichia coli. 24324139
2012-10-13 11:32:00 Data show the active site histidine of histidine phosphocarrier protein HPr, His-15, is buried within the active site cleft of IIA(Chb) formed at the interface of two adjacent subunits of the IIA(Chb) trimer. 22593574
