IUBMB Enzyme Nomenclature


Accepted name: glutarate dioxygenase

Reaction: glutarate + 2-oxoglutarate + O2 = (S)-2-hydroxyglutarate + succinate + CO2

Other name(s): csiD (gene name)

Systematic name: glutarate, 2-oxoglutarate:oxygen oxidoreductase ((S)-2-hydroxyglutarate-forming)

Comments: Requires iron(II). The enzyme, characterized from the bacteria Escherichia coli and Pseudomonas putida, participates in L-lysine degradation in many bacteria. It provides an alternative route for L-glutarate degradation that does not proceed via CoA-activated intermediates.
