What is Study on the Binding of Luteolin to Bovine Serum Albumin about?
Binding of luteolin (LU) to bovine serum albumin (BSA) was investigated at 298, 308 and 318 K at pH 7.4 using spectrophotometric techniques such as fluorescence emission, circular dichroism (CD). The data obtained from fluorescence quenching experiments showed that LU was bound to BSA and binding constants and the number of binding sites (n ≈ 1) were obtained. The thermodynamic parameters H 0 , S 0 , G 0 at different temperatures were calculated. They indicated that both hydrophobic forces and hydrogen bonds are the major interactions between LU and BSA. A value of 3.12 nm for the average distance r between LU (acceptor) and tryptophan residue (Trp) of BSA (donor) was derived from the fluorescence resonance energy transfer. The effects of some common metal ions on the binding are also considered. Besides, the interaction of BSA with LU led to a change in the conformation of BSA.
