ADP-binding subunit of the dihydroxyacetone kinase, which is responsible for the phosphoenolpyruvate (PEP)-dependent phosphorylation of dihydroxyacetone. DhaL-ADP is converted to DhaL-ATP via a phosphoryl group transfer from DhaM and transmits it to dihydroxyacetone binds to DhaK. dihydroxyacetone + phosphoenolpyruvate = dihydroxyacetone phosphate + pyruvate Polyol metabolism; glycerol degradation. Homodimer. The dihydroxyacetone kinase complex is composed of a homodimer of DhaM, a homodimer of DhaK and the subunit DhaL. Repressed by GolR. Unlike the carbohydrate-specific transporters of the PTS, the complex DhaKML has no transport activity.
