Isochorismatase-like domain-containing protein
FMNH2 + Oxygen + Uracil → Flavin Mononucleotide + Hydrogen Ion + Peroxyaminoacrylate
Peroxyaminoacrylate + Water → 3-Aminoacrylate + Carbamic acid + Hydrogen Ion
Carbamic acid + 2 Hydrogen Ion → Ammonium + Carbon dioxide
2-Aminoacrylic acid + Hydrogen Ion + Water → Ammonium + Malonic semialdehyde
3-Aminoacrylate + an unknown reduced electron acceptor → 2-Aminoacrylic acid + an unknown oxidized electron acceptor
Hydrogen Ion + Malonic semialdehyde + NADPH → Hydroxypropionic acid + NADP
