Abstract :

We discovered the new, hexagonal crystal form of lipase B from Candida antarctica (CAL-B). The NAG (N-acetyl-D-glucosamine) molecules which were closing the glycosylation site in the orthorhombic form in our hexagonal structure unexpectedly adopt an open conformation. We do not know whether the opening and closing of the glycosylation site by the ��?lid��? NAG moiety, could be related to the opening and closing of the active center of the enzyme upon substrate binding and product release. The packing of molecules in the hexagonal crystal makes the active center of the enzyme very well accessible for the ligand, which, in our opinion, may help in the enzyme-ligand complex formation.
