Protein

Dihydropyrimidinase

Gene

pyd2

Organism
Dictyostelium discoideum (Slime mold)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Catalyzes the second step of the reductive pyrimidine degradation, the reversible hydrolytic ring opening of dihydropyrimidines. Can catalyze the ring opening of 5,6-dihydrouracil to N-carbamyl-alanine and of 5,6-dihydrothymine to N-carbamyl-amino isobutyrate.1 Publication

Catalytic activityi

5,6-dihydrouracil + H2O = 3-ureidopropanoate.

Cofactori

Zn2+Note: Binds 2 Zn(2+) ions per subunit.
