Crystallization of genetically engineered active maltose-binding proteins, including an immunogenic viral epitope insertion.

Abstract excerpt

Three mutants of the maltose- or maltodextrin-binding protein encoded by the malE gene of Escherichia coli, with extensive genetic changes, have been purified and crystallized in different crystal forms. Two of these mutant proteins, MalE178 and MalE341, carry net deletions of seven and 13 residues, respectively, near the surface of the molecule. These mutations have very little effect on either the transport...
