Escherichia coli str. K-12 substr. MG1655 (strain: K-12, substrain: MG1655)
Lineage
Bacteria; Pseudomonadota; Gammaproteobacteria; Enterobacterales; Enterobacteriaceae; Escherichia
Also known as
ECK3722
Summary
GlmS synthesis s negatively feedback regulated by glucosamine-6-phosphate, which probably causes YhbJ to cleave and inactivate the GlmZ sRNA; GlmZ upregulates glmS mRNA post-translationally (Kalamorz, 2007). [More information is available at EcoGene: EG10382]. L-glutamine:D-fructose-6-phosphate aminotransferase, or GFAT, catalyzes the first step in hexosamine biosynthesis. [More information is available at EcoCyc: EG10382].

    Title: The small RNA GlmY acts upstream of the sRNA GlmZ in the activation of glmS expression and is subject to regulation by polyadenylation in Escherichia coli.
  4. The biological function of GlmZ is to positively control the glmS mRNA in response to GlcN-6-P concentrations and that YhbJ negatively regulates GlmZ. As in yhbJ mutants GlcN-6-P has no effect, YhbJ is essential for sensing this metabolite.
