General Information
NamePCK1
DescriptionPhosphoenolpyruvate carboxykinase, cytosolic (ec 4.1.1.32) (phosphoenolpyruvate carboxylase) (pepck-c).
SpeciesHomo sapiens (NCBI taxonomy ID: 9606)
GO0004613 phosphoenolpyruvate carboxykinase (GTP) act... (TAS)
Domain Architecture (Details)
InterPro domains unassigned to SynO:
Phosphoenolpyruvate carboxykinase (GTP) (PEPCK) catalyzesthe formation of phosphoenolpyruvate by decarboxylation of oxaloacetate whilehydrolyzing GTP:GTP + oxaloacetate = GDP + phosphoenolpyruvate + CO2This is a rate limiting step in gluconeogenesis (the biosynthesis ofglucose). In vertebrates there are two isozymes: a cytosolic form whoseactivity is affected by hormones regulating this metabolic process (such asglucagon.r insulin) and a mitochondrial form.An essential cysteine residue has been proposed to be implicated in thecatalytic mechanism; this residue is located in the central part of PEPCK.
  IPR008209:Phosphoenolpyruvate carboxykinase (GTP)
This N-terminal domain identifies phosphoenolpyruvate carboxykinase (GTP) () and phosphoenolpyruvate carboxykinase (ATP) () (PEPCK) which catalyse the formation of phosphoenolpyruvate by decarboxylation of oxaloacetate while hydrolyzing either ATP or GTP.
  IPR008210:Phosphoenolpyruvate carboxykinase, N-terminal
IPR008209:PEPCK 
Evalue:-1e+125
