NMR Structural Studies on a DNA Four-Way Junction: Stacking Preference and Localization of the Metal-ion Binding Site.

abstract：:Interaction studies of bisphenol analogues; biphenol-A (BPA), bisphenol-B (BPB), and bisphenol-F (BPF) with bovine serum albumin (BSA) were performed using multi-spectroscopic and molecular docking studies at the protein level. The mechanism of binding of bisphenols with BSA was dynamic in nature. SDS refolding experi...
