This is very important because if it doesn't happen, the proteins get out of the cell to their targets and severe disease will ensue and kill the organism.
这是非常重要的，因为如果这未发生，蛋白质从细胞中出来进到其靶位置，严重疾病将会因而产生并杀伤有机体。
A lot of our vaccines only develop new antibodies and antibody memory is different from t cell memory because of the types of proteins they respond to.
我们研发的疫苗很多只是形成新的抗体，但是抗体记忆不同于T细胞记忆，因为它们是应答产生的各种蛋白质。
We hand that list over to the universities, the pharmaceuticals, the biotech companies to start developing new drugs because those mutated genes and their proteins are targets for new therapeutics.
我们把该列表交给了大学，制药厂，生物科技公司，开始开发新的药物，因为这些突变基因及其蛋白质是新的治疗靶点。
Why? Because animal proteins contain high levels of IGF-1, a hormone that is known to promote the growth of cancer cells.
为什么？因为动物蛋白含有高浓度的IGF - 1，是已知的促进肿瘤细胞的生长的激素。
Because metals are the catalysts for so much of biology, knowing how to engineer a supply of the right metals to the right proteins will be important to the success of these ventures.
因为金属在大多数生物的催化剂，所以掌控为目的蛋白提供合适的金属的方法对于合成生物学非常重要。
These metals were chosen because they lie towards opposite ends of a chemical series called the Irving-Williams series, such that selecting these metals for proteins should be especially demanding.
选择铜锰进行研究是因为它们位于欧文·威廉姆斯化学序列的对立两方，选择这些金属的蛋白应当有特定需求。
Also, weight loss aside, "breaking the fast" is a savvy nutrition strategy, because it's a chance to fit in servings of produce, whole grains, healthy fats, and lean proteins.
此外，不提减肥，“解除禁食”是懂行人的营养策略，因为吃早餐有机会吃到农产品，谷物类，有机会摄取健康的脂肪，优质的蛋白。
Because the LAP2 peptide can be fused to a number of different proteins, the method enables the selective labeling of certain subpopulations of proteins in specific subcellular compartments.
由于LAP2肽可以融合在一定数量的不同蛋白上，该方法能够选择性标记在某些特定的亚细胞亚群的蛋白。
This is because the fermentation process has helped to break down those hard-to-digest proteins and this makes it a great choice for people who are sensitive to other forms of soy.
这是因为它的发酵过程有助于分解那些难以消化的蛋白质，这对那些对其他类的大豆敏感的人来说是一个很好的选择。
But of potentially more value is finding the exact role that genes and proteins play in the brain in response to stimuli, he says, because genes also are affected by environment.
但是更大的价值是发现基因和蛋白在脑对刺激反应时的确切作用，他说，因为基因也受环境影响。
Because of its strong non-covalent interaction with biotin, streptavidin can be used to isolate biotinylated proteins (1,2).
因为它的强高亲和力非共价结合，链霉素亲和素可以用于检测和分离生物素化的蛋白（1.2）。
But this method proved difficult because membrane proteins are tricky to coax into the crystal form required for the X-ray technique, the study says.
研究声称，这一技术被证明很难使，因为膜结合蛋白很难结晶。
