Atomic mutations in annexin V--thermodynamic studies of isomorphous protein variants.

Abstract excerpt

We have recently developed methods for specific and high-level replacement of methionine with 2-aminohexanoic acid, selenomethionine and telluromethionine as isosteric and atomic analogues for structural investigations of human recombinant annexin V. The variants formed isomorphic crystals and retained the parent three-dimensional fold and bioactivities. Folding parameters were determined from thermal and...
