What it does, reaction by reaction
Pyrimidine Degradation Nucleotide Metabolism · Cytosol
N-Carbamyl-beta-alanine → beta-alanine
Converts N-Carbamyl-beta-alanine into beta-Alanine
› Notes
Beta-ureidopropionase catalyzes N-carbamyl-beta-alanine + H2O → beta-alanine + NH3 + CO2. This completes the uracil-derived ring-carbon/nitrogen disposal sequence.
N-Carbamyl-beta-aminoisobutyrate → beta-aminoisobutyrate
Converts N-Carbamyl-beta-aminoisobutyrate into beta-Aminoisobutyrate
› Notes
Beta-ureidopropionase catalyzes N-carbamyl-beta-aminoisobutyrate + H2O → beta-aminoisobutyrate + NH3 + CO2.
