364106 [NCBI]

Taxonomic lineage

Bacteria › Proteobacteria › Gammaproteobacteria › Enterobacteriales › Enterobacteriaceae › Escherichia

Protein attributes

Sequence length	321 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	Not highly important in E.coli as glucose is transported into the cell by the PTS system already as glucose 6-phosphate. HAMAP MF_00524
Catalytic activity	ATP + D-glucose = ADP + D-glucose 6-phosphate. HAMAP MF_00524
Subcellular location	Cytoplasm By similarity.
Sequence similarities	Belongs to the bacterial glucokinase family.
