UniProtKB - Q13057 (COASY_HUMAN)

Protein

Bifunctional coenzyme A synthase

Gene

COASY

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Bifunctional enzyme that catalyzes the fourth and fifth sequential steps of CoA biosynthetic pathway. The fourth reaction is catalyzed by the phosphopantetheine adenylyltransferase, coded by the coaD domain; the fifth reaction is catalyzed by the dephospho-CoA kinase, coded by the coaE domain. May act as a point of CoA biosynthesis regulation.1 Publication

Catalytic activityi

ATP + pantetheine 4'-phosphate = diphosphate + 3'-dephospho-CoA.
ATP + 3'-dephospho-CoA = ADP + CoA.

Kineticsi

  1. KM=7.6 mM for 4'-phoshopantetheine
  2. KM=145 mM for ATP (in the PPAT reaction)
  3. KM=16.7 mM for dephospho-CoA
  4. KM=34.4 mM for ATP (in the DPCK reaction)

    Pathwayi: coenzyme A biosynthesis

    This protein is involved in step 4 and 5 of the subpathway that synthesizes CoA from (R)-pantothenate.
    Proteins known to be involved in the 5 steps of the subpathway in this organism are:
    1. Pantothenate kinase 1 (PANK1), Pantothenate kinase 3 (PANK3), Pantothenate kinase 4 (PANK4), Pantothenate kinase 2, mitochondrial (PANK2), Pantothenate kinase 4 (PANK4), Pantothenate kinase 4, Pantothenate kinase 4
    2. Phosphopantothenate--cysteine ligase (PPCS)
    3. Phosphopantothenoylcysteine decarboxylase (PPCDC)
    4. Bifunctional coenzyme A synthase (COASY)
    5. Bifunctional coenzyme A synthase (COASY)
    This subpathway is part of the pathway coenzyme A biosynthesis, which is itself part of Cofactor biosynthesis.
    View all proteins of this organism that are known to be involved in the subpathway that synthesizes CoA from (R)-pantothenate, the pathway coenzyme A biosynthesis and in Cofactor biosynthesis.

    Involvement in diseasei

    Neurodegeneration with brain iron accumulation 6 (NBIA6)1 Publication
    The disease is caused by mutations affecting the gene represented in this entry.
    Disease descriptionA neurodegenerative disorder associated with iron accumulation in the brain, primarily in the basal ganglia. It is characterized by progressive motor and cognitive dysfunction beginning in childhood or young adulthood. Patients show extrapyramidal motor signs, such as spasticity, dystonia, and parkinsonism.
