| 1. | Like light meromyosin, tropomyosin contains two peptide chains in a coiled coil conformation .
象轻酶解肌球蛋白一样，原肌球蛋白含有两个肽链，其构型为盘旋螺旋。 |
| 2. | Alpha helix a highly stable structure in which peptide chains are coiled to form a spiral
螺旋：蛋白质多肽链本身的折叠和盘绕的方式。 |
| 3. | Protease ( proteinase ) an enzyme that catalyzes the hydrolysis of peptide bonds in proteins to produce peptide chains and amino acids
蛋白酶：指催化蛋白质中肽键水解为多肽链和氨基酸的酶。 |
| 4. | Such a huge amount of types is due to the different sequences of amino acids which compose the proteins in the peptide chains
造成种类如此众多的原因主要是20种参与蛋白质组成的氨基酸在肽链中的排列顺序不同所引起的。 |
| 5. | It showed two results . one is that this toxin contains two proteins , the molecular weight of these proteins are similar to each other . the other result is that hntxa is a protein which has two peptide chains
对该毒素进行蛋白质n端测序，结果发现该毒素有两个n端，这表明该毒素或者是一个不纯的物质，它由两个分子量近似的蛋白组成；或者是一个由两条肽链组成的蛋白。 |
| 6. | The enzyme of microbial transglutaminase ( mtg ) can modify the structure and properties of proteins through catalyzing an acyl transfer reaction of a - carboxyamide group of glutamine residue in a peptide chain , resulting the cross - linking of proteins
摘要微生物谷氨酰胺转胺酶( mtg )可通过催化蛋白质谷氨酰胺的酰基转移反应改变蛋白质的结构和性质，是一种有广泛应用前景的重要新型酶制剂。 |
| 7. | So it has been found that this polymorphism of sod was changed under different experimental conditions , which showed that the polymorphism was not caused by the difference of genes or the difference of length or side groups of the peptide chains which was caused during the processing after transcript or the purification
由此排除了其是由不同基因编码的同工酶或在转录后加工及分离纯化过程中形成肽链长短不一和酶分子侧链基团差异等微不均一性所造成的可能性。 |
| 8. | There are 4 cysteins in the protein hbfgf , cysteins 78 and 96 are localized on the surface of hbfgf , whereas cystein 34 is completely buried and cystein 101 is partly buried within the folded peptide chain . so the cys78 and cys96 are especially prone to intramolecular disulphide - bond formation . we converted these two cysteins into serines
同时对于155个氨基酸的hbfgf来说，其34 、 78 、 96和101位的四个半胱氨酸的巯基有形成二硫键的可能，是造成二聚体或多聚体的主要原因，其中cys34隐藏在分子内部， cys101部分包埋在分子中； cys78和cys96暴露在蛋白质的表面，很容易因cys78和cys96的游离巯基氧化，在不同的分子间形成错误的二硫键。 |
