ID 4.4.1.43 DE canavanine-gamma-lyase. CA H2O + L-canavanine = L-homoserine + N-hydroxyguanidine. CC -!- A pyridoxal 5'-phosphate protein. CC -!- The enzyme, characterized from the bacterium Pseudomonas CC canavaninivorans, cleaves a carbon-oxygen bond, releasing CC N-hydroxyguanidine and an unstable enamine product that tautomerizes CC to an imine form, which is attacked by a water molecule to form CC L-homoserine. //
