查询词典 proteases

In addition, a metabolic inhibitor, actinomycin D has no effect on enzymatic activities of caspase-1/ICE-like and caspase-3/CPP-32/like proteases during Fas-mediated CD4〓T cell apoptosis. These results indicate that the appearance of caspase-1/ICE-like and caspase-3/CPP32-1ike proteases activities is a post-translational activation of these proteases. It is likely these caspases constituently express in a inactive form in the cytosol of CD4〓T lymphocytes. Once the rest SEB-responsive CD4〓T cells are restimulted, those inactive caspases such as caspase-1/ICE-like and caspase-3/CPP32-1ike proteases are sequentially cleaved to become active forms, and the apoptotic signal is transducted to downstream signaling molecules, Finally leads to CD4〓T cells apoptosis.

另外，通过代谢抑制剂放线菌素D对超抗原SEB诱导静息SEB应答〓细胞凋亡过程中Caspase成员酶活性变化的研究表明Caspase-1／ICE样，Caspase-3／CPP32样胱氨蛋白酶并非新合成的信号分子，很可能以无活性方式组成性表达于静息SEB应答〓细胞胞浆，在超抗原SEB再次刺激诱导〓细胞凋亡早期，先后顺序活化，借以传递凋亡信号到下游信号分子，诱导〓细胞凋亡。

Several coterminous bands could be observed by PAGE of natural Eisenin Ⅰ and several coterminous peaks of Eisenin Ⅰ were also detected with MALDI-TOF-MS when the molecular weight of three main peaks are 24, 645, 25, 052 and 25, 281, separately. The amino acid composition of Eisenin Ⅰ(pI. 8) is specilized with high content of acidic amino acids and low content of alkaline amino acids; At the same time, the content of Ser and Thr are quite high and that of Lys, Met, Phe and Trp are quite low. Eisenin Ⅰ is highly homologous with serine proteases. Then, by fibrin plate assay, Eisenin Ⅰ was identified to be a plasmin and also a plasminogen activator, and the fibrinolytic activity was inhibited by PMSF (an inhibitor of serine proteases).

赤子素Ⅰ氨基酸组成特点为高的酸性氨基酸和低的碱性氨基酸含量，且Ser、Thr含量高而Lys、Met、Phe和Trp含量很低；等电聚焦电泳测得其等电点pI.8.N端序列比较结果显示赤子素Ⅰ与丝氨酸蛋白酶类高度同源，纤维蛋白平板法测得赤子素Ⅰ同时具有纤溶酶和纤溶酶激酶活性；通过PMSF对赤子素Ⅰ纤溶酶活性的抑制实验证明，赤子素Ⅰ属于丝氨酸蛋白酶类。

In the mosquito, some Tryp_SPc proteases make important contributions to the digestion of the blood meal.

该类基因的表达水平在吸血之后显著升高，并且扩张的基因相对于进化稳定的基因的表达量升高较高。

However, commercially available CPB purified from porcine pancreas was very expensive, and was not totally free of other proteases, such as trypsin and chymotrypsin.

到目前为止，商业途径获得的羧肽酶B 主要从猪胰脏中提取，使得产品价格昂贵，同时也不可避免地混杂有其它蛋白酶，如胰蛋白酶，胰凝乳蛋白酶。

RTX is domain of bacterial toxins, which has not been found in cysteine proteases in plant.

RTX结构域是细菌毒素家族蛋白所具有的一个功能域，在目前发现的植物半胱氨酸蛋白酶氨基酸均不含有RTX结构域。

Thus, it is likely that shedding is mediated both by proteases and by disassociation of the non-covalent interaction between the α- and β-subunits.
