EC 3.5.1.110

Accepted name: peroxyureidoacrylate/ureidoacrylate amidohydrolase

Reaction: (1) (Z)-3-ureidoacrylate peracid + H2O = (Z)-3-peroxyaminoacrylate + CO2 + NH3 (overall reaction)
(1a) (Z)-3-ureidoacrylate peracid + H2O = (Z)-3-peroxyaminoacrylate + carbamate
(1b) carbamate = CO2 + NH3 (spontaneous)
(2) (Z)-2-methylureidoacrylate peracid + H2O = (Z)-2-methylperoxyaminoacrylate + CO2 + NH3 (overall reaction)
(2a) (Z)-2-methylureidoacrylate peracid + H2O = (Z)-2-methylperoxyaminoacrylate + carbamate
(2b) carbamate = CO2 + NH3 (spontaneous)

Glossary: ureidoperacrylic acid = (Z)-3-ureidoacrylate peracid = (2Z)-3-(carbamoylamino)prop-2-eneperoxoic acid
(Z)-2-methylureidoperacrylic acid = (Z)-2-methylureidoacrylate peracid = (2Z)-3-(carbamoylamino)-2-methylprop-2-eneperoxoic acid

Other name(s): RutB
