چکیده

The crystal structure of Bacillus subtilis -amylase, in complex with the pseudotetrasaccharide inhibitor acarbose, revealed an hexasaccharide in the active site as a result of transglycosylation. After comparison with the known structure of the catalytic-site mutant complexed with the native substrate maltopentaose, it is suggested that the present structure represents a mimic intermediate in the initial stage of the catalytic process.

Preparation and crystallization G6-amylase from alkalophilic Bacillus sp.707 was expressed by Bacillus subtilis 207-25. The enzyme was crystallized by the hanging drop vapor diffusion method using the reservoir solution containing 50% (v/v) 2methylpentane-2, 4-diol, 100 mM Tris-HCl (pH 8.5) and 200 mM ammonium phosphate. Calcium chloride and sodium chloride were added to final 1 mM in the drop ...

Structure of Bacillus halmapalus α-amylase crystallized with and without the substrate analogue acarbose and maltose

Recombinant Bacillus halmapalus alpha-amylase (BHA) was studied in two different crystal forms. The first crystal form was obtained by crystallization of BHA at room temperature in the presence of acarbose and maltose; data were collected at cryogenic temperature to a resolution of 1.9 A. It was found that the crystal belonged to space group P2(1)2(1)2(1), with unit-cell parameters a = 47.0, b ...

Structure of a Bacillus halmapalus family 13 alpha-amylase, BHA, in complex with an acarbose-derived nonasaccharide at 2.1 A resolution.

The enzymatic digestion of starch by alpha-amylases is one of the key biotechnological reactions of recent times. In the search for industrial biocatalysts, the family GH13 alpha-amylase BHA from Bacillus halmapalus has been cloned and expressed. The three-dimensional structure at 2.1 A resolution has been determined in complex with the (pseudo)tetrasaccharide inhibitor acarbose. Acarbose is fo...
