Scrutiny of chain-length and N-terminal effects in α-helix folding: a molecular dynamics study on polyalanine peptides.

abstract：:The present study employed the spectroscopic techniques, i.e. fluorescence, and circular dichroism (CD) and the molecular docking approach to investigate the mechanism of interaction of a potent anticancer glucosinolate, sinigrin (SIN), with bovine serum albumin (BSA). SIN binding to BSA resulted in the quenching of i...
