“…The overall architecture and main-chain conformations of the molecule are almost identical to those of the wild-type enzyme (Morishita et al, 1997) , except in the region where the maltotetraose is bound in the active site in the complexed crystals. The geometries of the two bound calcium ions are also the same.…”

“…About 100 bound water molecules were found at the same site within distances of 1 A Ê among the wild-type and two complexed crystals. Buried water molecules found in the wild-type crystal (Morishita et al, 1997) were almost conserved. The disordered loop composed of the residues 66 to 72 was more rigid in the complex type 1 crystal, but still showed disorder in the type 2 crystal (a little less than in the wild-type, but with high temperature factors).…”

“…The enzymology of the exo-amylase-which is responsible for the formation of maltotetraose as an end product-has been examined at the molecular level. This enzyme has also been cloned (231). Obradors and Aguilar demonstrated that polyethylene glycol was degraded to yield ethylene glycol, a substrate typically used by P. stutzeri strains (241).…”
