4-carboxymethylenebut-2-en-4-olide + H2O = 4-oxohex-2-enedioate | mechanism | Pseudomonas knackmussii | |
4-carboxymethylenebut-2-en-4-olide + H2O = 4-oxohex-2-enedioate | similar catalytic triads are found in alpha/beta hydrolase fold enzymes: DLH is the simplest one | Pseudomonas knackmussii | |
4-carboxymethylenebut-2-en-4-olide + H2O = 4-oxohex-2-enedioate | the active-site Cys123 residue is part of a triad of residues consisting of Cys123, His202 and Asp171, and is reminiscent of the serine/cysteine proteases | Pseudomonas knackmussii |
