trans-o-Hydroxybenzylidenepyruvate hydratase-aldolase ( EC 4.1.2.45, 2′-hydroxybenzalpyruvate aldolase, NsaE, tHBPA hydratase-aldolase) is an enzyme with systematic name (3E)-4-(2-hydroxyphenyl)-2-oxobut-3-enoate hydro-lyase. [1] [2] [3] [4] This enzyme catalyses the following chemical reaction
- (3E)-4-(2-hydroxyphenyl)-2-oxobut-3-enoate + H2O salicylaldehyde + pyruvate
This enzyme is involved in naphthalene degradation.
