Sequence statusComplete.
Protein existenceInferred from homology

General annotation (Comments)

Function

Catalyzes the formation of succinate and glyoxylate from isocitrate, a key step of the glyoxylate cycle. May be involved in the assimilation of one-carbon compounds via the isocitrate lyase-positive serine pathway By similarity.

Catalytic activity

Isocitrate = succinate + glyoxylate.

Pathway

Carbohydrate metabolism; glyoxylate cycle; (S)-malate from isocitrate: step 1/2.

Subunit structure

Homotetramer By similarity.

Subcellular location

Cytoplasm.

Sequence similarities

Belongs to the isocitrate lyase/PEP mutase superfamily. Isocitrate lyase family.
