show Brenda entry

EC number

4.4.1.24

Accepted name

(2R)-sulfolactate sulfo-lyase

Reaction

(2R)-3-sulfolactate = pyruvate + hydrogensulfite

Other name(s)

Suy, SuyAB, 3-sulfolactate bisulfite-lyase, sulfolactate sulfo-lyase (ambigious), (2R)-3-sulfolactate bisulfite-lyase (pyruvate-forming)

Systematic name

(2R)-3-sulfolactate hydrogensulfite-lyase (pyruvate-forming)

CAS registry number

1256650-35-7

Comment

Requires iron(II). This inducible enzyme participates in cysteate degradation by the bacterium Paracoccus pantotrophus NKNCYSA and in 3-sulfolactate degradation by the bacterium Chromohalobacter salexigens. The enzyme is specific for the (R) isomer of its substrate.
