Summary
DhaR is an auto-repressor of dhaR transcription. [More information is available at EcoGene: EG13902]. "Dihydroxyacetone Regulator," DhaR, is negatively autoregulated and coordinately activates transcription of the divergent Dha operon (dhaKLM), which encodes three subunits of the dihydroxyacetone (Dha) kinase . [More information is available at EcoCyc: G6628].
