the interaction of sulfur mustard with aminoacids and proteins has been investigated in this study. rats were injected with sublethal doses of sulfur mustard subcutaneously and intraperitoneally. at different time intervals, plasma and urine samples were collected. the binding affinity of sulfur mustard with urinary and plasma proteins and enzymes was studied for the first time using non-ideal ...

Nonspecific interactions related to physicochemical properties of bacterial cell surfaces, such as hydrophobicity and electrostatic charge, are known to have important roles in bacterium-host cell encounters. Streptococcus pneumoniae (pneumococcus) expresses multiple, surface-exposed, choline-binding proteins (CBPs) which have been associated with adhesion and virulence. The purpose of this stu...

background: recently, botulinum neurotoxin (bont)-derived recombinant proteins have been suggested as potential botulism vaccines. here, with concentrating on bont type e (bont/e), we studied two of these binding domain-based recombinant proteins: a multivalent chimer protein, which is composed of bont serotypes a, b and e binding subdomains, and a monovalent recombinant protein, which contains...

Various anatomically distinct regions from postmortem human brain were analyzed for o-bungarotoxin (a-BuTX) binding and choline acetyltransferase activity. There was a heterogeneous distribution of both cr-BuTX and enzyme activity in the regions studied. Although levels of cY-BuTX binding were lower than those reported in other mammalian brain studies, the relative regional concentration was, i...

generally, plasma proteins owe their binding capacity to the presence of aminoacid units which enter into intra- and intermolecular hydrophobic bonding with a diverse range of endo- and exogenous chemical substances. the intermolecular interactions between the hydrophobic areas of drug molecules and those of plasma proteins play an important role in drug-macromolecular complex formation and sta...

Choline is a small molecule that occupies a key position in the biochemistry of all living organisms. Recent studies have strongly implicated choline metabolites in cancer, atherosclerosis and nervous system development. To detect choline and its metabolites, existing physical methods such as magnetic resonance spectroscopy and positron emission tomography are often limited by the poor spatial ...
