UniProtKB - P16638 (ACLY_RAT)

Protein

ATP-citrate synthase

Gene

Acly

Organism
Rattus norvegicus (Rat)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

ATP-citrate synthase is the primary enzyme responsible for the synthesis of cytosolic acetyl-CoA in many tissues. Has a central role in de novo lipid synthesis. In nervous tissue it may be involved in the biosynthesis of acetylcholine.

Catalytic activityi

ADP + phosphate + acetyl-CoA + oxaloacetate = ATP + citrate + CoA.

Cofactori

Mg2+By similarity

Activity regulationi

Phosphorylation results in a 6-fold increase in V(max) and the conversion of citrate dependence from sigmoidal to hyperbolic. Fructose 6-phosphate (F6P) is also a potent activator.By similarity

Post-translational modificationi

Phosphorylated on two serines and one threonine. Phosphorylation on Thr-446 and Ser-450 depends on the phosphorylation state of Ser-454. Phosphorylation on Ser-454 is decreased by prior phosphorylation on the other 2 residues.2 Publications
The N-terminus is blocked.
ISGylated.By similarity
Acetylated at Lys-539, Lys-545 and Lys-553 by KAT2B/PCAF. Acetylation is promoted by glucose and stabilizes the protein, probably by preventing ubiquitination at the same sites. Acetylation promotes de novo lipid synthesis. Deacetylated by SIRT2 (By similarity).By similarity
Ubiquitinated at Lys-539, Lys-545 and Lys-553 by UBR4, leading to its degradation. Ubiquitination is probably inhibited by acetylation at same site (By similarity).By similarity
