Molecular rules for chemo- and regio-selectivity of Candida antarctica lipase B in peptide acylation reactions
International audience The chemo- and regio-selectivity of the lipase B of Candida antarctica (CALB) in peptide acylation by oleic acid was investigated combining experimental and theoretical methodologies. Molecular dynamics and docking simulations were performed to study the selectivity of CALB to...
