Protein

PEP-dependent dihydroxyacetone kinase, ADP-binding subunit DhaL

Gene

dhaL

Organism
Escherichia coli (strain K12)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-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 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.1 Publication

Pathwayi: glycerol degradation

Miscellaneousi

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.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
