Escherichia coli K-12 substr. MG1655 Compound: 2-deoxy-D-glucose

Synonyms: 2-deoxyglucose

2-deoxy-D-glucose induces the Sgr mediated glucose stress response in E. coli K-12 which shuts down the ManXYZ system for transport [Rice11]. SetA, encoding a sugar efflux protein is co-transcribed with SgrS under stress conditions [Sun11] leading to the hypothesis that that SetA may export non-metabolisable sugar analogues however the experimental evidence for this is uncertain [Liu99a, Sun11].

Chemical Formula: C6H12O5

Molecular Weight: 164.16 Daltons
