The role of weakly polar and H-bonding interactions in the stabilization of the conformers of FGG, WGG, and YGG: an aqueous phase computational study.

30 Oct 2008 The energetics of intramolecular interactions on the conformational potential energy surface of the terminally protected N-Ac-Phe-Gly-Gly-NHMe (FGG), N-Ac-Trp-Gly-Gly-NHMe (WGG), and N-Ac-Tyr-Gly-Gly-NHMe (YGG) tripeptides was investigated. To ... Read more...

Midbody targeting of the ESCRT machinery by a noncanonical coiled coil in CEP55.

22 Oct 2008 The ESCRT (endosomal sorting complex required for transport) machinery is required for the scission of membrane necks in processes including the budding of HIV-1 and cytokinesis. An essential step in cytokinesis is recruitment of the ESCRT-I ... Read more...

The dual histidine motif in the active site of Pin1 has a structural rather than catalytic role.

8 Oct 2008 The catalytic domain of the peptidyl-prolyl cis/ trans isomerase Pin1 is a member of the FKBP superfold family. Within its active site are two highly conserved histidine residues, H59 and H157. Despite their sequence conservation in parvulin PPIase ... Read more...
