High-resolution structure of intramolecularly proteolyzed human mucin-1 SEA domain
(Elsevier Science, 2020-03)
SEA domains are ubiquitous in large proteins associated with highly glycosylated environments. Certain SEA domains undergo intramolecular proteolysis involving a nucleophilic attack of a serine hydroxyl group on the preceding ...
Peptide model XXVIII: An exploratory ab initio and density functional study on the side-chain-backbone interaction in N-acetyl-L-cysteine-N-methylamide and N-formyl-L-cysteinamide in their γL-backbone conformations
(National Research Council Canada-NRC Research Press, 2002-07-01)
A conformational and electronic study on the energetically preferred conformations (γL) of N- and C-protected L-cysteine (P-CONH-CH(CH2SH)-CONH-Q, where P and Q may be H or Me) was carried out. After restraining the backbone ...
Vitellogenesis in spiders: First analysis of protein changes in different reproductive stages of Polybetes pythagoricus
(Springer Verlag Berlín, 2019-04-05)
Vitellogenesis represents one of the most vital processes of oviparous species during which various proteins, carbohydrates, and lipids are synthesized and stored inside the developing oocytes. Through analyzing protein ...
Analysis of Brain Nuclei Accessible to Ghrelin Present in the Cerebrospinal Fluid
(Pergamon-Elsevier Science Ltd., 2013-12-03)
Ghrelin is a stomach-derived peptide hormone that acts in the brain to regulate many important physiological functions. Ghrelin receptor, named the growth hormone secretagogue receptor (GHSR), is present in many brain areas ...
Interaction between the plant ApDef1 defensin and Saccharomyces cerevisiae results in yeast death through a cell cycle- and caspase-dependent process occurring via uncontrolled oxidative stress
(Elsevier Science, 2017-01)
Background Plant defensins were discovered at beginning of the 90s' however, their precise mechanism of action is still unknown. Herein, we studied ApDef1-Saccharomyces cerevisiae interaction. Methods ApDef1-S. cerevisiae ...

A helix-coil transition induced by the metal ion interaction with a grafted iron-binding site of the CyaY protein family
(Royal Society Of Chemistry, 2015-02)
Iron-protein interactions are involved in electron transfer reactions. Alterations of these processes are present in a number of human pathologies; among them, in Friedreich's ataxia, in which a deficiency of functional ...
Determination of a predictive cleavage motif for eluted major histocompatibility complex class II ligands
(Frontiers Media S.A., 2018-08)
CD4+ T cells have a major role in regulating immune responses. They are activated by recognition of peptides mostly generated from exogenous antigens through the major histocompatibility complex (MHC) class II pathway. ...
