Crystallographic Evidence for Substrate Ring Distortion and Protein Conformational Changes During Catalysis in Cellobiohydrolase Cel6A from Trichoderma Reesei
Structure, 7:1035-, 1999

PubMed Abstract: Cel6A is one of the two cellobiohydrolases produced by Trichoderma reesei. The catalytic core has a structure that is a variation of the classic TIM barrel. The active site is located inside a tunnel, the roof of which is formed mainly by a pair of loops.
