Operon evidence: S1 nuclease mapping
Reference: Hahn J, et al. (1993)
Comments: A minor promoter exists between comEA and comEB. The terminators proposed in the paper do not agree well with the S1 nuclease mapping result. A second termination site was found experimentally by Hahn et al. about 230 basepairs from the stop codon.
