Regulated Operon: glpTQ

Genes
Genes Synonyms Direction Genome position Function COG ID Genus clusters
glpT ybeE - 233982..235316 glycerol-3-phosphate permease COG2271 glpT-BAC  
glpQ ybeD - 233002..233883 glycerophosphoryl diester phosphodiesterase COG0584 x0792-BAC  

Operon evidence: Northern blotting (2.6 kb transcript)
Reference: Nilsson RP, et al. (1994), Antelmann H, et al. (2000)
Comments: The internal promoter in front of glpQ, leading to a 1.1 kb transcript. Transcriptional terminatation at the stem-loop downstream of the glpT promoter is thought to be alleviated by GlpP binding to the ribosomal antiterminator (RAT) sequence in the presence of glycerol-3-phosphate.
