Peroxyureidoacrylate/ureidoacrylate amidohydrolase

Peroxyureidoacrylate/ureidoacrylate amidohydrolase (EC 3.5.1.110, RutB) is an enzyme with systematic name (Z)-3-ureidoacrylate peracid amidohydrolase. This enzyme catalyses the following chemical reaction sequences:

(Z)-3-ureidoacrylate peracid + H₂O ⇌ (Z)-3-peroxyaminoacrylate + CO₂ + NH₃ (overall reaction)
1. (Z)-3-ureidoacrylate peracid + H₂O ⇌ (Z)-3-peroxyaminoacrylate + carbamate
2. carbamate ⇌ CO₂ + NH₃ (spontaneous)
(Z)-2-methylureidoacrylate peracid + H₂O ⇌ (Z)-2-methylperoxyaminoacrylate + CO₂ + NH₃ (overall reaction)
1. (Z)-2-methylureidoacrylate peracid + H₂O ⇌ (Z)-2-methylperoxyaminoacrylate + carbamate
2. carbamate ⇌ CO₂ + NH₃ (spontaneous)

The enzyme also shows activity towards ureidoacrylate.
