There were 5 . 9 tip residues in cml . the purified cml was modified with n - bromosuccinimide ( nbs ) in hac - naac buffer containing 8mol / l urea or not
在含8mol l脲和不含脲的缓冲体系中，用n -溴代丁二酰亚胺( nbs )修饰cml的色氨酸残基。
The change of agglutinating activity , cd spectrum and fls of lra in different temperature , ph and different chemicals indicated that lra had partial hemagglutinating activity at ph2 . 0 ( 50 % ) , a temperature above 100 ( 60 % ) and after modified by n - bromosuccinimide ( mbs ) , the activity lost completely , modified by depc , the lra had a little activity , the other groups modified such as arg , tyr , glu , asp did n ' t effect the hemagglutinating activity of lra . the result indicated that trp residues were essential to the hemagglutinating activity and were involved in carbohydrate - binding site
研究不同温度、 ph和基团特异性化学修饰后lra凝血活性和促淋巴细胞有丝分裂的变化、圆二色谱和荧光光谱的变化，当温度达80以上时，活性开始下降，到100时活性有60 %保留:当ph为2时，活性保留50 % ， ph为4一12对活性的影响不大;用nbs修饰trp后， t即的旦一叫睬基的破坏使活性完全丧失，表明trp对凝血活性是至关重要的， arg 、 tyr 、 glu 、 asp被修饰后， lra的凝血活性并未受到大的影响，但tyr修饰后lra的促有丝分裂活性降低
