YcjW DNA-binding transcriptional dual regulator

Synonyms: YcjW
YcjW is a transcriptional regulator involved in the control of carbohydrate metabolism genes [1]. ycjW was identified in a screen for genes that reduce the lethal effects of stress. A ycjW insertion mutant is more sensitive than wild type to mitomycin C [].
