Brain leukotriene C4 binding sites are S-alkylglutathione binding sites
European Journal of Pharmacology, 1989Leukotriene C4 binding to mouse brain membranes was readily displaced by S-alkylglutathione derivatives, with the affinity of the test compound increasing as the alkyl chain length increases. S-decylglutathione was as potent as leukotriene C4. These data suggest that brain membrane leukotriene C4 binding sites are S-alkylglutathione binding sites ...

Cryptophycin 1 is a new cytotoxic antimicrotubule agent with excellent antitumor activity. The methods of Sackett (Biochemistry, 34, 7010-7019, 1995), utilizing the selective and specific proteolysis of alpha- and beta-tubulin by trypsin and chymotrypsin, was used to identify the cryptophycin 1 binding site on tubulin.

Anatomy of lipase binding sites: the scissile fatty acid binding site
Chemistry and Physics of Lipids, 1998Shape and physico-chemical properties of the scissile fatty acid binding sites of six lipases and two serine esterases were analyzed and compared in order to understand the molecular basis of substrate specificity. All eight serine esterases and lipases have similar architecture and catalytic mechanism of ester hydrolysis, but different substrate ...

Abstract An examination of the effect of dibutylchloromethyltin/chloride on the carbodiimide binding proteolipid of mitrochondrial ATPase has revealed that in the presence of the alkyltin, (1) binding of dicyclohexycarbodiimide is decreased (2) the electron spin resonance spectrum of a nitroxide analogue of dicyclohexylcarbodiimide exhibits line ...

Metal ions have a role in a variety of important functions in proteins including protein folding, assembly, stability, conformational change, and catalysis. The presence or absence of a given metal ion is crucial to the conformation or activity of over one third of all proteins.

What makes a binding site a binding site?
Current Opinion in Structural Biology, 1995Organic probe molecules have recently been used to define hydrophobic binding sites on the surface of proteins. It appears that the presence of water on the surface of a protein plays a crucial role in the interaction between that protein and its binding site.

Benzodiazepine-Binding Site and Gaba-Binding Site
1983There is a body of experimental evidence to suggest that the benzodiazepine-binding site, the GABA-binding site and the chloride ionophore are functionally correlated. To elucidate this issue, the interactions among these components in both membrane-bound state and soluble state are examined.

Abstract: The distribution and characterization of specific melatonin binding sites were studied using 125I‐melatonin. Autoradiography revealed only three sites of specific melatonin binding in brain: the suprachiasmatic nuclei, the median eminence, and the small part of choroid plexus at the caudal end of the fourth ventricle.
