Identification
Name:Carbonic acid
DescriptionCarbonic acid (ancient name acid of air or aerial acid) is the only inorganic carbon acid, and has the formula H2CO3. It is also a name sometimes given to solutions of carbon dioxide in water, which contain small amounts of H2CO3. The salts of carbonic acids are called bicarbonates (or hydrogencarbonates) and carbonates. (wikipedia)

P00864
Molecular weight:
99062
Reactions
Phosphate + oxaloacetate = H(2)O + phosphoenolpyruvate + HCO(3)(-).
General function:
Involved in ATP binding
Specific function:
2 ATP + L-glutamine + HCO(3)(-) + H(2)O = 2 ADP + phosphate + L-glutamate + carbamoyl phosphate

Reactions
2 ATP + L-glutamine + HCO(3)(-) + H(2)O = 2 ADP + phosphate + L-glutamate + carbamoyl phosphate.
General function:
Involved in phosphoribosylaminoimidazole carboxylase activity
Specific function:
Possesses an ATPase activity that is dependent on the presence of AIR (aminoimidazole ribonucleotide). The association of purK and purE produces an enzyme complex capable of converting AIR to CAIR efficiently under physiological condition
Gene Name:
purK
Uniprot ID:
P09029
Molecular weight:
39461
Reactions
ATP + 5-amino-1-(5-phospho-D-ribosyl)imidazole + HCO(3)(-) = ADP + phosphate + 5-carboxyamino-1-(5-phospho-D-ribosyl)imidazole.
General function:
Involved in glutamine catabolic process
Specific function:
2 ATP + L-glutamine + HCO(3)(-) + H(2)O = 2 ADP + phosphate + L-glutamate + carbamoyl phosphate
Gene Name:
carA
Uniprot ID:
P0A6F1
Molecular weight:

Reactions
2 ATP + L-glutamine + HCO(3)(-) + H(2)O = 2 ADP + phosphate + L-glutamate + carbamoyl phosphate.
General function:
Involved in acetyl-CoA carboxylase activity
Specific function:
Controls translation of mRNA for both itself and the alpha-subunit (accA) by binding to a probable hairpin in the 5' of the mRNA. Binding to mRNA inhibits translation; this is partially relieved by acetyl-CoA. Increasing amounts of mRNA also inhibit enzyme activity
Gene Name:
accD
Uniprot ID:
P0A9Q5
Molecular weight:
33322
Reactions
ATP + acetyl-CoA + HCO(3)(-) = ADP + phosphate + malonyl-CoA.
General function:
Involved in acetyl-CoA carboxylase activity
Specific function:
Component of the acetyl coenzyme A carboxylase (ACC) complex. First, biotin carboxylase catalyzes the carboxylation of biotin on its carrier protein (BCCP) and then the CO(2) group is transferred by the carboxyltransferase to acetyl-CoA to form malonyl-CoA
Gene Name:
accA
Uniprot ID:
P0ABD5
Molecular weight:
35241
Reactions
ATP + acetyl-CoA + HCO(3)(-) = ADP + phosphate + malonyl-CoA.
General function:
Involved in carbonate dehydratase activity
Specific function:
Reversible hydration of carbon dioxide. Carbon dioxide formed in the bicarbonate-dependent decomposition of cyanate by cyanase (cynS) diffuses out of the cell faster than it would be hydrated to bicarbonate, so the apparent function of this enzyme is to catalyze the hydration of carbon dioxide and thus prevent depletion of cellular bicarbonate
