Taxonomic lineage

Eukaryota › Fungi › Dikarya › Ascomycota › Saccharomycotina › Saccharomycetes › Saccharomycetales › Saccharomycetaceae › Saccharomyces

Protein attributes

Sequence length	500 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Two isoenzymes, hexokinase-1 and hexokinase-2, can phosphorylate keto- and aldohexoses in yeast, whereas a third isoenzyme, GLK, is specific for aldohexoses. All glucose phosphorylating enzymes are involved in glucose uptake.
Catalytic activity	ATP + D-glucose = ADP + D-glucose 6-phosphate.
Subunit structure	Monomer.
Miscellaneous	Present with 21100 molecules/cell in log phase SD medium. Ref.5
Sequence similarities	Belongs to the hexokinase family.
