Fatty acid transport and fatty acid-binding proteins.
Les protkines de liaison ou de transfert des acides gras sont prCsentes dans les fluides intraet extra-cellulaires de la plupart des organismes. Elles jouent un r61e dans le transport ou le ciblage des acides gras, mais peuvent kgalement agir en interaction avec different processus par la modulation de la concentration de la liaison libre. Quelques protkines de liaison des acides gras sont asse...
متن کاملPolyene fatty acid interactions with recombinant intestinal and liver fatty acid-binding proteins. Spectroscopic studies.
Binding and proximity relationships of fatty acids with recombinant rat liver fatty acid-binding protein (L-FABP) and intestinal fatty acid-binding protein (I-FABP) were studied with absorption and fluorescence spectroscopy. Protein aromatic amino acids were examined in the absence and presence of bound fatty acid. Second derivative absorbance spectroscopy of the apo- and holoproteins suggested...
متن کاملFatty acid transfer between multilamellar liposomes and fatty acid-binding proteins.
A simple experimental system was developed for studying the movement of long-chain fatty acids between multilamellar liposomes and soluble proteins capable of binding fatty acids. Oleic acid was incorporated into multilamellar liposomes containing cholesterol and egg yolk lecithin and incubated with albumin or hepatic fatty acid-binding protein. It was found that the fatty acid transferred from...
متن کاملKinetics of fatty acid interactions with fatty acid binding proteins from adipocyte, heart, and intestine.
Rate constants for the interaction of fatty acids (FA) with fatty acid binding proteins (FABP) from adipocyte (A-FABP), heart (H-FABP), and intestine (I-FABP) were determined by using stopped-flow fluorometry and ADIFAB, the fluorescent probe of free fatty acids (FFA), or a new FFA probe, ADIFAB2, constructed by derivatizing with acrylodan the Leu72 --> Ala mutant of I-FABP. ADIFAB2, because it...
متن کاملStudies on fatty-acid-binding proteins. The purification of rat liver fatty-acid-binding protein and the role of cysteine-69 in fatty acid binding.
1. A new, simple and high-yield procedure is described for the purification of hepatic fatty-acid-binding protein from rat liver using naphthylaminodecyl-agarose as an affinity column. 2. Cysteine-69 is shown to react slowly, but quantitatively, with 5,5'-dithiobis-(2-nitrobenzoic acid) (DTNB), indicating that the thiol group is free, but may be buried within the protein. 3. Fatty acids do not ...
