|Gene:||pfkA||Accession Number: G-9171 (MetaCyc)|
Synonyms: pfkC, PF1784
Species: Pyrococcus furiosus
Subunit composition of
ADP-dependent phosphofructokinase = [PfkA]4
ADP-dependent phosphofructokinase subunit = PfkA
ADP-dependent phosphofructokinase and ADP-dependent glucokinase are members of a unique family unrelated to bacterial ATP-dependent glucokinase, or eukaryotic hexokinase (reviewed in [Verhees03]).
The native molecular mass of the enzyme partially purified from cell-free extracts of Pyrocuccus furiosus was determined by gel filtration chromatography [Tuininga99].
The subunit molecular mass of the purified, recombinant protein was determined by SDS-PAGE [Tuininga99].
