IntEnz Enzyme Nomenclature
EC 4.1.2.45

Names

Accepted name:
trans-o-hydroxybenzylidenepyruvate hydratase-aldolase
Other names:
2'-hydroxybenzalpyruvate aldolase
NsaE
tHBPA hydratase-aldolase
Systematic name:
(3E)-4-(2-hydroxyphenyl)-2-oxobut-3-enoate hydro-lyase

Reaction

Comments:

This enzyme is involved in naphthalene degradation. The enzyme catalyses a retro-aldol reaction in vitro, and it accepts a broad range of aldehydes and 4-substituted 2-oxobut-3-enoates as substrates [4].
