PEP-dependent dihydroxyacetone kinase, ADP-binding subunit DhaL

UniProtKB accession:  P76014

Grouped By:  Matching UniProtKB accession

UniProtKB description:  ADP-binding subunit of the dihydroxyacetone kinase, which is responsible for the phosphoenolpyruvate (PEP)-dependent phosphorylation of dihydroxyacetone (PubMed:11350937). DhaL-ADP is converted to DhaL-ATP via a phosphoryl group transfer from DhaM and transmits it to dihydroxyacetone bound to DhaK (PubMed:11350937). DhaL acts also as coactivator of the transcription activator DhaR by binding to the sensor domain of DhaR (PubMed:15616579). In the presence of dihydroxyacetone, DhaL-ADP displaces DhaK and stimulates DhaR activity (PubMed:15616579). In the absence of dihydroxyacetone, DhaL-ADP is converted by the PTS to DhaL-ATP, which does not bind to DhaR (PubMed:15616579).
