Reactions known to consume the compound:

allantoin degradation IV (anaerobic) :
ammonium + CO2 + ATP ← carbamoyl-phosphate + ADP + 2 H+

UMP biosynthesis :
L-aspartate + carbamoyl-phosphateN-carbamoyl-L-aspartate + phosphate + H+

Not in pathways:
carbamoyl-phosphate + ATP + HypE → HypE-S-carboxamide + AMP + diphosphate + phosphate

Reactions known to produce the compound:

allantoin degradation IV (anaerobic) :
oxamate + carbamoyl-phosphate ← oxalurate + phosphate

arginine biosynthesis I (via L-ornithine) , UMP biosynthesis :
2 ATP + L-glutamine + hydrogen carbonate + H2O → carbamoyl-phosphate + L-glutamate + 2 ADP + phosphate + 2 H+

Not in pathways:
2 ATP + hydrogen carbonate + ammonium → 2 ADP + carbamoyl-phosphate + phosphate + 2 H+

Reactions known to both consume and produce the compound:

arginine biosynthesis I (via L-ornithine) :
L-ornithine + carbamoyl-phosphate ↔ L-citrulline + phosphate + H+
