The results of its intrinsic fluorescence spectroscopy and fluorescence phase diagram showed that when the guanidine hydrochloride concentration in denaturation solution was about 1.0 mol/L, there existed a partially folded intermediate of Bacillus amyloliquefaciens a-amylase during its unfolding procedure, which followed a three-state model; the result of its fluorescence probe showed that when the guanidine hydrochloride concentration in denaturation solution was about 1.0 mol/L, there existed some stable hydrophobic regions, which could interact with a hydrophobic reagent 8-anilino-1-naphthalene sulfonic acid, in the partially folded intermediate of Bacillus amyloliquefaciens a-amylase; and the results of fluorescence quenching using acrylamide and potassium iodide as quenchers showed the distribution of Trp residues in Bacillus amyloliquefaciens a-amylase in different denaturation solution, with the maximum number (8) of tryptophan residues in a partially folded intermediate Bacillus amyloliquefaciens a-amylase molecule could be quenched by potassium iodide; and the results of their protein electrophoresis and SEC showed that no aggregate or aggregate precipitation of Bacillus amyloliquefaciens a-amylase formed during the whole unfolding procedure of Bacillus amyloliquefaciens a-amylase induced by guanidine hydrochloride.
