3.1.1.45 4-carboxymethylenebut-2-en-4-olide + H2O = 4-oxohex-2-enedioate mechanism Pseudomonas knackmussii
a
3.1.1.45 4-carboxymethylenebut-2-en-4-olide + H2O = 4-oxohex-2-enedioate the catalytic triad Cys123, His202 and Asp171 is a hybrid of the standard triads found in cysteine: Cys-His-Asn and serine: Ser-His-Asp proteases Pseudomonas knackmussii
a
3.1.1.45 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
a
3.1.1.45 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
