Cryptophycin 1 binds to tubulin at a site distinct from the colchicine binding site and at a site that may overlap the vinca binding site

Cancer Letters, 1996
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.

Antibody Binding Sites

1996
This chapter assesses advances in the understanding and manipulation of antibody binding sites and variable regions. The antigen binding region of an antibody reduced to a 25-kDa minimum comprises of a noncovalent heterodimer of V H and V L domains.

Anatomy of lipase binding sites: the scissile fatty acid binding site

Chemistry and Physics of Lipids, 1998
Shape 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 ...

Benzodiazepine-Binding Site and Gaba-Binding Site

1983
There 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.

Melatonin Binding Sites

Journal of Neurochemistry, 1988
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.

Interaction of the dibutylchloromethyltin chloride binding site with the carbodiimide binding site in mitochondria

Biochemical and Biophysical Research Communications, 1980
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 ...

What makes a binding site a binding site?

Current Opinion in Structural Biology, 1995
Organic 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.

Brain leukotriene C4 binding sites are S-alkylglutathione binding sites

European Journal of Pharmacology, 1989
Leukotriene 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 ...

Ethanol binding sites on proteins

Journal of Molecular Graphics and Modelling, 2017
This study is on the analysis of ethanol binding sites on 3D structures of nonredundant proteins from the Protein Data Bank. The only one amino acid residue that is significantly overrepresented around ethanol molecules is Tyr. There are usually two or more Tyr residues in the same ethanol binding site, while residues of Thr, Asp and Gln are ...

On the receptor binding site of relaxins

International Journal of Peptide and Protein Research, 1988
Relaxin plays a critical role in viviparity and has recently been implicated as a hormone of oviparity as well. In most mammals relaxin causes the widening of the birth canal during parturition and suppresses uterine motility during pregnancy. Relaxins isolated from several species have shown a great deal of sequence variability, and speculations ...
