The study investigates the binding site of chloro(triethylphosphine)gold(I) (ClAuPEt3) in bovine serum albumin (BSA) using electron paramagnetic resonance (EPR) spectroscopy. The researchers employed 3-maleimidoPROXYL as a spin marker to identify the binding site of ClAuPEt3. They found that ClAuPEt3 competes with the spin marker for binding to the cysteine residue (Cys-34) in BSA. At low ClAuPEt3:BSA molar ratios, the spin marker with weak rotational limitation is more easily displaced than the strongly immobilized marker. However, as the ClAuPEt3:BSA molar ratio increases, the displacement of the strongly immobilized marker becomes more prevalent. The study suggests that ClAuPEt3 binding induces conformational changes in BSA, particularly affecting the Cys-34 residue. The findings provide insights into the interaction between gold compounds and serum albumin, which is relevant for understanding drug transport and therapeutic applications of gold(I) complexes in antirheumatic therapy.
