The N-terminal region of photocleavable peptides that bind HLA-DR1 determines the kinetics of fragment release. [PDF]
Major Histocompatibility Complex class II (MHC-II) molecules bind peptides and present them to receptors on CD4+ T cells as part of the immune system's surveillance of pathogens and malignancy.

Fragment synthesis of disulfide-containing peptides
A new strategy for solid phase peptide synthesis in the fragment synthesis based on the use of 2-Cl-trityl resin as carrier to obtain protected peptide-resin and Rink Amide Resin, HOBT/HBTU or PyBOP/DIPEA or HATU/DIPEA as the coupling method is described. The highlights of this method are:•Simple.•Low cost.•Solid phase based.

From Synthetic Fragments of Endogenous Three-Finger Proteins to Potential Drugs
The proteins of the Ly6 family have a three-finger folding as snake venom α-neurotoxins, targeting nicotinic acetylcholine receptors (nAChRs), and some of them, like mammalian secreted Ly6/uPAR protein (SLURP1) and membrane-attached Ly-6/neurotoxin ...

Folding propensities of peptide fragments of myoglobin [PDF]
Myoglobin has been studied extensively as a paradigm for protein folding. As part of an ongoing study of potential folding initiation sites in myoglobin, we have synthetized a series of peptides covering the entire sequence of sperm whale myoglobin. We report here on the conformation preferences of a series of peptides that cover the region from the A ...

A high level of mutation enables the influenza A virus to resist antibiotics previously effective against the influenza A virus. A portion of the structure of hemagglutinin HA is assumed to be well-conserved to maintain its role in cellular fusion, and ...

Folding molecular dynamics simulation of T-peptide, a HIV viral entry inhibitor : Structure, dynamics, and comparison with the experimental data [PDF]
Peptide T is a synthetic octapeptide fragment, which corresponds to the region 185-192 of the gp120 HIV coat protein and functions as a viral entry inhibitor. In this work, a folding molecular dynamics simulation of peptide T in a membrane-mimicking (DMSO) solution was performed with the aim of characterizing the peptide's structural and dynamical ...

Ion-Induced Dipole Interactions and Fragmentation Times : C$α$ -C$β$ Chromophore Bond Dissociation Channel [PDF]
The fragmentation times corresponding to the loss of the chromophore (C$\alpha$-- C$\beta$ bond dissociation channel) after photoexcitation at 263 nm have been investigated for several small peptides containing tryptophan or tyrosine. For tryptophan-containing peptides, the aromatic chromophore is lost as an ionic fragment (m/z 130), and the ...
