Abstract
Genes encoding the ammonia-dependent asparagine synthetase (asnA) and asparaginyl-tRNA synthetase (asnS) have been cloned from Lactobacillus bulgaricus ATCC 11842. The nucleotide sequence suggests that asnA and asnS are organized as one operon and regulated by the tRNA-directed transcription antitermination mechanism (T. M. Henkin, Mol. Microbiol. 13:381-387, 1994).
摘要
编码氨依赖性天冬酰胺合成酶（asnA）和天冬酰胺-tRNA合成酶（asnS）的基因已从保加利亚乳杆菌ATCC 11842中克隆出来。核苷酸序列表明，asnA和asnS被组织成一个操纵子，并受tRNA指导的转录抗终止机制调控（T.M.亨金，《分子微生物学》13:381 - 387，1994年）。
