YebK DNA-binding transcriptional dual regulator

Synonyms: YebK, YebK-2-dehydro-3-deoxy-D-gluconate 6-phosphate
YebK is a transcriptional regulator implicated in the adaptation to the transition from rich medium to cellobiose minimal medium, reducing the length of the lag phase [1] Expression of YebK is higher in cellobiose minimal medium than in glucose minimal medium. DNA binding of YebK is reversed by 2-keto-3-deoxygluconate-6-phosphate (KDPG) [1] Genome-wide YebK binding sites were determined in vivo by chromatin immunoprecipitation method combined with lambda exonuclease digestion (ChIP-exo) in glucose M9 minimal medium [2].
