+ 81768..82694 cysteine synthetase A COG0031 cysK-BAC-1 cysK-BAC-2 cysK-STA cysK-STR  

Operon evidence: Northern blotting, RNAse protection assay of the 3' end of the mRNA.
Reference: De Sazieu A, et al. (1997), BSORF
Comments: BSORF shows additional transcripts starting further upstream, but terminating at the same position. The RNAse protection assay showed that transcription terminates at the last T of the T-stretch TTTTTTT. This terminator is slightly leaky.
