LITERATURE
expression only upon growth in presence of nicotine
-
gene encoding demethylating gamma-N-methylaminobutyrate oxidase mabO is located on megaplasmid pAO1 and forms an operon with purU- and folD-like genes. Transcripts of the purU-mabO-folD operon can only be detected in bacteria grown in the presence of nicotine. Transcription of the operon is controlled by transcriptional regulator PmfR
