Using papain to hydrolyze the legumin and vicilin respectively showed that it could obtain higher DH from legumin than from vicilin, and the emulsifying activity of legumin hydrolysates was also increased more than vicilin hydrolysates. It was easier to hydrolyze the β-sheet fractions than α-helical fractions of broad bean legumin by papain, but to vicilin the β-sheet fractions was difficult to be hydrolyzed.

发现Papain对11S的水解程度大于7S，11S水解物的乳化活性也高于7S水解物；对水解物的圆二色性分析表明：蚕豆11S球蛋白的β-折叠结构易于被木瓜蛋白酶作用，而7S球蛋白的α-螺旋结构易于被木瓜蛋白酶作用；蛋白质分子中的α-螺旋结构对乳状液的形成和稳定起着重要作用。

The matrix metalloproteinase is a group of proteinase of the most importance, and plays an important role in invasion and matastasis of tumor, usually expresses excessively on the surface of malignant tumor cells.

基质金属蛋白酶(matrix metalloproteinases ，MMPs)是其中最为重要的一组蛋白酶，在肿瘤的侵袭和转移中有着重要的作用，通常在恶性肿瘤细胞表面过度表达。

The use of acid protease in the production of machine-made yellow rice wine (by non-glutinous rice) could provide nitrogen source for the growth and reproduction of microzyme and accelerate rapid reproduction of microzyme (which improve fermentation stability and capability), decompose proteins (which advanced the use of amylum in raw materials and increased wine yield), and settled the commonly existed problems of low aminophenol nitrogen content and non-sugar solids content.

酸性蛋白酶在粳米黄酒酿造中可为酵母菌的生长繁殖提供氮源，促进酵母菌的快速繁殖，提高发酵过程的稳定性和能力；分解原料中的蛋白质物质，促进对原料淀粉的利用，提高原料的出酒率；可有效解决机制粳米黄酒过程普遍存在的低氨基酸态氮、低非糖固形物的问题；酸性蛋白酶在发酵酒醅中的澄清作用，为黄酒成品解决非生物浑浊提供了方法。

The Mucor GH101 was studied in this paper. Acid protease under the condition of incubation temperature 28 ℃ was produced.

实验采用GH101毛霉，培养温度为28 ℃，所分泌的蛋白酶为酸性蛋白酶。

But the hydrolysate has strong bitter taste and has to get rid of during the following process. Mucor has been used in sufu, a well-known delicious Chinese cheese that is made with soybean curd, making in China for hundreds years.

腐乳毛霉能够产生一定数量的蛋白酶，可以将豆腐坯中的大豆球蛋白(11S)水解为分子量较小的肽类(P.C.L0)并具有良好的风味，毛霉蛋白酶有可能成为制备大豆多肽的优选酶种。

Objective To determine the activities of matrix metalloproteinase-2 and -9 in odontoblast of healthy and carious teeth and explore the roles of MMP-2 and MMP-9 in pathogenic mechanism of dental caries.

目的 比较健康牙齿和龋齿成牙本质细胞中基质金属蛋白酶－2MMP-2）和基质金属蛋白酶－9(MMP-9）的活性，以探讨MMP-2和MMP-9在龋病发病机制中的作用。

In order to get CPP with lower N/P ratio, casein was first hydrolyzed with pancreatin until the DH reached 12%, and then Neutrase, a microbial protease, was added to increase the DH of casein hydrolyzate by an additional 3%.

在胰酶作用于酪蛋白的DH达12％基础上，选用微生物中性蛋白酶继续水解，使中性蛋白酶作用于酪蛋白水解液的DH达3％，以制备N/P更小的CPP。
