4.2.1.177

Accepted name:

(2S)-3-sulfopropanediol dehydratase

Reaction:

(2S)-2,3-dihydroxypropane-1-sulfonate = 3-oxopropane-1-sulfonate + H₂O

Glossary:

(2S)-2,3-dihydroxypropane-1-sulfonic acid = (2S)-3-sulfopropanediol = (S)-DHPS

Other name(s):

hpfG (gene name); (S)-DHPS dehydratase

Systematic name:

(2S)-2,3-dihydroxypropane-1-sulfonate hydro-lyase

Comments:

The enzyme, characterized from the bacterium Klebsiella oxytoca, participates in (2S)-2,3-dihydroxypropane-1-sulfonate degradation. The active form of the enzyme contains a glycyl radical that is generated by a dedicated activating enzyme via chemistry involving S-adenosyl-L-methionine (AdoMet) and a [4Fe-4S] cluster.
