Taxonomic lineage

cellular organisms › Bacteria › Proteobacteria › Gammaproteobacteria › Pseudomonadales › Pseudomonadaceae › Pseudomonas › Pseudomonas aeruginosa group › Pseudomonas aeruginosa

Protein attributes

Sequence length	531 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

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. UniProtKB P28298
Pathway	Carbohydrate metabolism; glyoxylate cycle; (S)-malate from isocitrate: step 1/2.
Subcellular location	Cytoplasm By similarity.
Sequence similarities	Belongs to the isocitrate lyase/PEP mutase superfamily. Isocitrate lyase family.
