General annotation (Comments)

Function

ADP-binding subunit of the dihydroxyacetone kinase, which is responsible for phosphorylating dihydroxyacetone. DhaL-ADP receives a phosphoryl group from DhaM and transmits it to dihydroxyacetone. DhaL-ADP acts also as a coactivator by binding to the sensor domain of DhaR. DhaL-ATP is inactive. Ref.5

Pathway

Polyol metabolism; glycerol degradation.

Subunit structure

The dihydroxyacetone kinase complex is composed of a homodimer of DhaM, a homodimer of DhaK and the subunit DhaL.

Domain

The DhaL subunit corresponds to the C-terminal part of ATP-dependent dihydroxykinases and the DhaK subunit corresponds to the N-terminal part.

Miscellaneous

Unlike the carbohydrate-specific transporters of the PTS, the complex DhaKML has no transport activity.

Complexation with ADP increases the thermal unfolding temperature from 40 to 65 degrees Celsius. The tightly bound ADP participates in a double displacement phosphoryl transfer reaction and thus plays the same role as histidines, cysteines and aspartic acids in other phosphoprotein intermediates.

Sequence similarities

Contains 1 DhaL domain.
