Second, even if a microbe produces collagenase and other proteases, enzymes that break down proteins, they CAN'T reach the collagen protein due to its interaction with calcium.

第二，即使微生物能产生胶原酶和其他蛋白酶，些酶可以分解蛋白质，但由于胶原蛋白与钙的相互作用，它们无法到达胶原蛋白。

Neutrophils make an enzyme called neutrophil elastase, a protease capable of breaking down elastin, which is an extracellular matrix protein that gives elasticity and strength to lung tissues.

中性粒细胞产生中性粒细胞弹性蛋白酶，该酶能够水解弹性蛋白；弹性蛋白是一种细胞外基质蛋白，赋予肺组织弹性和韧性。

An enzyme is a protein that's a catalyst, it speeds up or accelerates a chemical reaction, just as the chymosin over here is accelerating the curdling of the milk.

酶是一种蛋白，也是一种催化剂，它能加快化学反应速率，就像里的凝乳酶能让牛奶加速凝固。

We might just break it down into smaller molecules, and then we use those smaller molecules to produce enzymes or proteins or neurotransmitters or hormones or cell membranes.

我们可能只是将其分解成更小的分子，然后利用些更小的分子来生产酶或蛋白质或神经递质或激素或细胞膜。

Scientists wanted to know the structure of a protein-cutting enzyme produced by a retrovirus similar to HIV. They haven't been able to solve the protein structure using standard computational methods.

科学家们很想掌握由反向病毒所衍生的蛋白剪切酶的结构，而反向病毒是指，比如HIV样的病毒。类蛋白结构是能通过标准算法法则推导就直接得出的。

When I eat that big steak we have to have two enzymes that break down those proteins called trypsin and chymotrypsin and they're each going to work on different sides.

当我享用那块大牛排时，我们需要两种酶来分解那些蛋白质，它们分别是胰蛋白酶和糜蛋白酶。两种酶各自在同的部位发挥作用。

They could also identify distinct peroxisomes, small organelles involved in a metabolism, by staining for a protein called catalase, and it could map the precise subcellular localization of key functional proteins.

他们还能通过标记一种名为过氧化氢酶的蛋白质，识别出同的过氧化物酶体，些小型细胞器参与代谢过程，并能绘制出关键功能蛋白在亚细胞水平的精确定位图。

Enzymes are proteins, and proteins are expensive. So these compounds — known as brush border enzymes — can just sit around and process food as it passes by, without your body having to make new ones.

酶是蛋白质，蛋白质很昂贵。所以些化合物——被称为刷状边界酶——可以在食物经过时无所事事地处理食物，而你的身体必制造新的。
