Protein

PTS-dependent dihydroxyacetone kinase, ADP-binding subunit DhaL

Gene

dhaL

Organism
Lactococcus lactis subsp. lactis (strain IL1403) (Streptococcus lactis)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

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.1 Publication

Miscellaneous

Unlike the carbohydrate-specific transporters of the PTS, the complex DhaKML has no transport activity.1 Publication

Catalytic activityi

Phosphoenolpyruvate + glycerone = pyruvate + glycerone phosphate.By similarity

Cofactori

Mg2+1 Publication

Pathwayi: glycerol degradation

This protein is involved in the pathway glycerol degradation, which is part of Polyol metabolism.Curated
View all proteins of this organism that are known to be involved in the pathway glycerol degradation and in Polyol metabolism.
