研究结论

Date Results Publications
2020-05-09 10:17:00 Single-particle cryo-electron microscopy shows that the ExbB pentamer encloses a dimer of ExbD in its transmembrane pore, and not a monomer as previously reported. Ton subcomplex consists of a pentamer of ExbB enclosing a dimer of ExbD TM domains. The essential Asp25 residues on ExbD are in close proximity to the conserved Thr 148 and 181 on ExbB. 31602407
2019-06-01 10:52:00 Channel current measurement and 2D crystallography support the existence and transition of the two oligomeric states in membranes. The hexameric complex consists of six ExbB subunits and three ExbD transmembrane helices enclosed within the central channel. 29661272
2015-07-25 10:27:00 ExbB-ExbD-TonB form complex in molar ratios of 4:1:1. 25802296
2013-12-07 11:23:00 A 10-residue-deletion scanning mutagenesis indicated that the cytoplasmic loop of ExbB (residues 40 to 129) was essential for TonB system activity. 23913327
2013-07-27 12:26:00 Consideration of combined data excludes ExbB transmembrane domain residues from direct participation in a proton pathway. 23603742
