NiceZyme View of ENZYME: EC 6.3.5.5

Official Name
Carbamoyl-phosphate synthase (glutamine-hydrolyzing).
Alternative Name(s)
Carbamoyl phosphate synthetase.
Carbamoyl-phosphate synthetase (glutamine-hydrolyzing).
Carbamoylphosphate synthetase II.
Carbamyl phosphate synthetase (glutamine).
CPS.
GD-CPSase.
Glutamine-dependent carbamoyl-phosphate synthase.
Glutamine-dependent carbamyl phosphate synthetase.
Reaction catalysed
2 ATP + L-glutamine + HCO(3)(-) + H(2)O <=> 2 ADP + phosphate + L-glutamate + carbamoyl phosphate
Comment(s)
  • The product carbamoyl phosphate is an intermediate in the biosynthesis of arginine and the pyrimidine nucleotides.
  • The enzyme from Escherichia coli has three separate active sites, which are connected by a molecular tunnel that is almost 100 A in length.
  • The amidotransferase domain within the small subunit of the enzyme hydrolyzes glutamine to ammonia via a thioester intermediate.
  • The ammonia migrates through the interior of the protein, where it reacts with carboxy phosphate to produce the carbamate intermediate.
  • The carboxy-phosphate intermediate is formed by the phosphorylation of bicarbonate by ATP at a site contained within the N-terminal half of the large subunit.
  • The carbamate intermediate is transported through the interior of the protein to a second site within the C-terminal half of the large subunit, where it is phosphorylated by another ATP to yield the final product, carbamoyl phosphate.
  • Formerly EC 2.7.2.9.
