Insights into the Energetics of Membrane-Bound Peptides : Towards an Understanding of the Structural Organisation of Membrane Proteins
… proteins, namely the monotopic and bitopic peptides. Analysis of several aspects of these peptides such as their orientation, electrostatics and association is reported here. The environment of these peptides is represented by a continuum model that distinguishes between water, membrane core …

Regulation of Expression of a Retroviral Transforming Gene and its Cellular Homolog
… revertants of rat cells transformed by FSV. Analysis of the defect of the two ts mutants of FSV revealed that P130 is the transforming protein of FSV and that its kinase activity plays a crucial role in cell transformation by this virus. v-fps, the transforming gene of FSV is homologous to a …

Applications of Ion Mobility Mass Spectrometry - Screening for SUMOylation and Other Post-Translational Modifications
… (IMMS)-based method of screening for isopeptides from SUMOylated substrates. The model conjugates poly-SUMO2 and poly-SUMO3 were digested by trypsin/chymotrypsin to produce small linear peptides and isopeptides with a QQQTGG tag on the substrate lysine. Using solution conditions to …

Structural characterization of spider coating petide [i.e., peptide] 1 and 2 of the black widow spider, Latrodectus hesperus
… <p>In this study, the novel aqueous glue coating peptides found on the silk fiber of the black widow spider, spider coating peptide 1 and 2, were investigated. Using circular dichroism, it was determined that SCP-1 and SCP-2 display predominantly alpha-helical secondary structures. In temperature …

The role of PYY in regulating energy balance and glucose homeostasis
Peptide YY (PYY) is a gut-derived hormone that is renowned for its effects on satiety. Reduced satiety in obese people has been attributed to low fasting and postprandial PYY levels. However, it has not been determined whether low PYY levels are the cause or the outcome of obesity. Moreover, the …
