EC 3.1.1.92

Accepted name: 4-sulfomuconolactone hydrolase

Reaction: 4-sulfomuconolactone + H2O = maleylacetate + sulfite

Glossary: 4-sulfomuconolactone = 4-carboxymethylen-4-sulfobut-2-en-olide = 2-(5-oxo-2-sulfo-2,5-dihydrofuran-2-yl)acetic acid
maleylacetate = (2Z)-4-oxohex-2-enedioate

Systematic name: 4-sulfomuconolactone sulfohydrolase

Comments: The enzyme was isolated from the bacteria Hydrogenophaga intermedia and Agrobacterium radiobacter S2. It catalyses a step in the degradation of 4-sulfocatechol.
