摘要
Quantum chemical and molecular dynamics investigations have been performed on model systems for Candida rugosa lipase (CRL) to study mechanistic and conformational features of the catalytic hydrolysis. Based on X-ray data, a simplified model of the CRL substrate complex was created for the PM3 and ab initio calculations, including the amino acid residues both of the catalytic triad and the oxyanion hole.
