S. Ilkim et al., LACTOBACILLUS-BULGARICUS ASPARAGINE SYNTHETASE AND ASPARAGINYL-TRANSFER-RNA SYNTHETASE - COREGULATION BY TRANSCRIPTION ANTITERMINATION, Journal of bacteriology, 178(8), 1996, pp. 2459-2461
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 t
ranscription antitermination mechanism (T. M. Henkin, Mel. Microbiol.
13:381387, 1991).
