glnR
+ 1877155..1877562 transcriptional regulator COG0789 glnR-STA glnR-STR  
glnA
+ 1877623..1878957 glutamine synthetase COG0174 glnA-BAC glnA-STA glnA-STR  

Operon evidence: S1 nuclease mapping of the 5' and 3' end of the mRNA
Reference: Strauch MA, et al. (1988), Fisher SH, et al. (1984)
Comments: The S1 nuclease mapping of the 3' terminus showed that transcription ends in the TTTTTT stretch of the indicated terminator. The stem-loop downstream of glnR may be a readthrough terminator, or alternatively a transcriptional pause site or RNA processing site.
