修饰系统 meaning in English
modification system
Examples
- The chief aim of the present study is to characterize the deleted region of s . lividans mutant strain zx1 which lacks dnd phenotype and sulphur modification , to localize and analyze the entire dnd cluster and to study the biological function and regulation of dnd genes
变钳青链霉菌突变株zx1由于染色体发生人片段缺失而丧失这种异常修饰系统( zhouetal . , 1994b ) 。首先对这段缺失区域进行了研究。 - A novel dna modification discovered in streptomyces lividans is different from dna methylation . this unusual modification causes wild type s . lividans dna sensitive to site - specific oxidative double - strand cleavage ( dnd phenotype , dna degradation )
变铅青链霉菌的dna异常修饰系统是一种不同于甲基化修饰的新型修饰系统，它可使变铅青链霉菌dna在电泳时易遭到氧化双链切割( dnd表型， dnadegradation ) ( zhouetal . , 1988 ) 。 - This unusual modification causes wild type s . lividans 1326 dna sensitive to site - specific oxidative double - strand cleavage ( dnd phenotype ) . preliminary study revealed that such dna modification involves incorporation of sulphur . the entire functional dnd cluster , 8 . 3kb in size , including 3 orfs - dnda , dndb and dndc was involved in this dna modification
野生型变铅青链霉菌具有一种不同于甲基化修饰的新型dna硫修饰系统，使dna在电泳时易遭到氧化双链切割而导致降解( dnd , dnadegradation )表型( zhouetal . , 1988 , 1994 , 1999 ) 。 - The dnd cluster seemed to express when it was carried by the high copy - number plasmid because complementation of individual dnda , dndb or dndc mutation could be observed and such expression did not seem to influence the normal dnd expression in wild type s . lividans 1326
而在高拷贝质粒上的dnd基因似乎是李爱英变铅青链霉菌dna异常修饰系统的分子生物学研究能表达的，因为它能红补分别在dn剧、 dndb和咖jc发生单个基因突变的菌株，而且这种表达似乎也不会影响野生型菌株1326中原有的dnd基因簇的表达。
