TRIS/MALTOTRIOSE COMPLEX OF CHIMAERIC AMYLASE FROM B. AMYLOLIQUEFACIENS AND B. LICHENIFORMIS AT 2.2A
Overview
Several chimeric alpha-amylases genes were constructed by an in vivo, recombination technique from the Bacillus amyloliquefaciens and Bacillus, licheniformis genes. One of the fusion amylases (hereafter BA2), consisting of residues 1-300 from B. amyloliquefaciens and 301-483 from B., licheniformis, has been extensively studied by X-ray crystallography at, resolutions between 2.2 and 1.7 A. The 3-dimensional structure of the, native enzyme was solved by multiple isomorphous replacement, and refined, at a resolution of 1.7 A. It consists of 483 amino acids, organized, similarly to the known B. lichiniformis alpha-amylase structure [Machius, et al. (1995) J. Mol. Biol. 246, 545-559], but features 4 bound calcium, ions. Two of these form part of a linear cluster of three ions, the, central ... [(full description)]
