UniProtKB - Q9I0K4 (ACEA_PSEAE)
Protein
Isocitrate lyase
Gene
PA2634
Organism
Pseudomonas aeruginosa (strain ATCC 15692 / DSM 22644 / CIP 104116 / JCM 14847 / LMG 12228 / 1C / PRS 101 / PAO1)
Status
Functioni
Involved in the metabolic adaptation in response to environmental changes. Catalyzes the reversible formation of succinate and glyoxylate from isocitrate, a key step of the glyoxylate cycle, which operates as an anaplerotic route for replenishing the tricarboxylic acid cycle during growth on fatty acid substrates.By similarity
Catalytic activityi
- EC:4.1.3.1By similarity
Cofactori
Mg2+By similarity
: glyoxylate cycle Pathwayi
This protein is involved in step 1 of the subpathway that synthesizes (S)-malate from isocitrate.By similarityProteins known to be involved in the 2 steps of the subpathway in this organism are:
- Isocitrate lyase (PA2634)
- Malate synthase G (glcB)
View all proteins of this organism that are known to be involved in the subpathway that synthesizes (S)-malate from isocitrate, the pathway glyoxylate cycle and in Carbohydrate metabolism.
