肽抗生素 meaning in English
peptide antibiotic
Examples
- They contribute to innate host defense against a number of bacterial and fungal pathogens , even some of the pathogens resistant to conventional antibiotics . more than 300 peptide antibiotics have been found so far , and some have natural or artificial mutants
迄今已从动物、植物、昆虫等生物体内分离到肽抗生素300多种，新的肽抗生素还在不断被发现，有的类别还发现存在多种突变体。 - Quinolones , tetracyclines , aminoglycosides , and so on . antimicrobial peptides are a new class of antibiotics discovered recent years , which are encoded by genes of organisms and chemically peptides , so they are also called as peptide antibiotics
肽抗生素( peptideantibiotics )或称为抗微生物肽( antimicrobialpeptide )则是近年来发现的由动物、植物、昆虫等生物体基因编码的具有抗生素样活性的肽类物质。 - In order to obtain a new peptide antibiotics mutant molecule with strong antimicrobial activity and / or more simple structure , a mutant library was often constructed by genetical method and then the desirable mutant molecule was screened out from the library
不同种类、不同突变体的肽抗生素活性有不同程度差异。为了获得结构简单、活性更强的肽抗生素，研究者们常常在克隆到肽抗生素分子后，通过构建其突变体库，从中筛选更理想的目的分子。 - In this dissertation , the following experiments are conducted : firstly , cloning of hpab - gene , i ) the amino acids sequences of 23 animal - peptide antibiotics were analyzed by multiple sequences alignment method and a pair of degenerated primers were designed according to the consensus sequence derived from mature peptides of some beta peptide antibiotics
人源肽抗生素hpab -的基因克隆：对动物23种型肽抗生素的氨基酸序列进行对比，选择部分相似性较高的序列，分析其成熟肽的结构特点，抽提型肽抗生素的一级结构特征，并以此为基础设计简并引物。
