产品介绍
来自猪胰腺的弹性蛋白酶已被用于UMP合成酶(尿苷-5-′单磷酸合成酶)的蛋白水解裂解。它也可和胶原酶一起用于将兔的胸腔、腹主动脉和内膜中的组织分散到单个细胞中。来自猪胰腺的弹性蛋白酶已被用于鉴定猪胰腺中的一种新型骨/钙代谢调节因子。来自猪胰腺的弹性蛋白酶还被用于研究中性粒细胞弹性蛋白酶的一种特异性合成抑制剂(ONO-5046)对狗急性出血性胰腺炎病程的影响。 Elastase from porcine pancreas has been used in a study to identify a novel bone/calcium metabolism-regulating factor in porcine pancreas. Elastase from porcine pancreas has also been used in a study to investigate the effect of a specific synthetic inhibitor of neutrophil elastase (ONO-5046) on the course of acute hemorrhagic pancreatitis in dogs. Elastase from porcine pancreas has been used in the proteolytic cleavage of UMP synthase (Uridine-5′-monophosphate synthase). It has also been used along with collagenase to disperse tissue into single cells from the thoracic media, abdominal aortic media and intima of rabbit.
生化机理
弹性蛋白酶是由 240 个氨基酸残基组成的单一多肽链,含有 4 个二硫键。分子量约为 25.9 kDa。这种酶被合成为无活性的酶原、弹性蛋白酶原,后者通过胰蛋白酶在 N 末端的有限蛋白水解转化为活性形式。 它是一种丝氨酸蛋白酶,具有广泛的特异性。它在小疏水氨基酸(如 Ile、Gly、Ala、Ser、Val 和 Leu )的羧基侧切割蛋白质。该酶还水解酰胺类及酯类,如 N-苯甲酰-L-丙氨酸甲酯。 pH 最佳值为 8.0-8.5 。它不需要任何激活剂,但可由二异丙基氟磷酸盐、苯甲磺酰氟、α2-巨球蛋白,α1-抗胰蛋白酶、磺酰氟、对二硝基苯基二乙磷酸盐和高盐浓度抑制。弹性蛋白酶广泛用于组织和细胞分离程序。对分离II型肺细胞有效。弹性蛋白酶水解弹性蛋白(弹性纤维的特定蛋白质)并消化血红蛋白、酪蛋白和纤维蛋白。
