Entry
EC 4.2.1.177                Enzyme                                 
Name
(2S)-3-sulfopropanediol dehydratase;
hpfG (gene name);
(S)-DHPS dehydratase
Class
Lyases;
Carbon-oxygen lyases;
Hydro-lyases
Sysname
(2S)-2,3-dihydroxypropane-1-sulfonate hydro-lyase
Reaction(IUBMB)
(2S)-2,3-dihydroxypropane-1-sulfonate = 3-oxopropane-1-sulfonate + H2O [RN:R12762]
Reaction(KEGG)
R12762
Substrate
(2S)-2,3-dihydroxypropane-1-sulfonate [CPD:C22383]
Product
3-oxopropane-1-sulfonate [CPD:C22384];
H2O [CPD:C00001]
Comment
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.
