Change in the crystal packing of soybean beta-amylase mutants substituted at a few surface amino acid residues.

Abstract excerpt

In spite of the high similarity of amino acid sequence and three-dimensional structure between soybean beta-amylase (SBA) and sweet potato beta-amylase (SPB), their quaternary structure is quite different, being a monomer in SBA and a tetramer in SPB. Because most of the differences in amino acid sequences are found in the surface region, we tested the tetramerization of SBA by examining mutations of residues...
