The results 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 amyloliquefaciensα-amylase;with the denaturation concentration increasing,the stable hydrophobic regions disappered.the results of fluorescence quenching using acrylamide and potassium iodide as quenchers showed that using acrylamide as quenchers,with the protein denaturation extent increasing,the number of Trp that can be quenched increased untill all the Trp residues were quenched;Using potassium iodide as quenchers,with the maximum number(8) of tryptophan residues in a partially folded intermediate Bacillus amyloliquefaciensα-amylase molecule could be quenched by potassium iodide;with the denaturation concentration increasing,the number of Trp that can be quenched decreased to 5.the results of their protein electrophoreses and SEC showed that no aggregate or aggregate precipitation of Bacillus amyloliquefaciensα-amylase formed during the whole unfolding/refolding procedure of Bacillus amyloliquefaciensα-amylase induced by guanidine hydrochloride or urea.
ANS外源荧光探针结果表明:盐酸胍诱导的芽孢杆菌α-淀粉酶分子去折叠过程中存在着能够与探针分子1-苯胺基-8-萘磺酸结合的稳定的疏水区域;而随着芽孢杆菌α-淀粉酶分子在盐酸胍溶液中变性程度的加深,这一疏水区域逐步被瓦解。丙烯酰胺和碘化钾猝灭结果表明:在盐酸胍溶液中,随着芽孢杆菌α-淀粉酶分子变性程度的进一步加深,其分子内能够被丙烯酰胺接近的色氨酸残基逐渐增多,直至全部被猝灭。但位于芽孢杆菌α-淀粉酶分子表面的能够被碘化钾猝灭的色氨酸残基,在中间态芽孢杆菌α-淀粉酶分子中数目达到最大的8个,而随着其分子变性程度的进一步加深,反而减少至5个。
