Sysname
(2S)-2,3-dihydroxypropane-1-sulfonate sulfite-lyase
Reaction(IUBMB)
(2S)-2,3-dihydroxypropane-1-sulfonate = hydroxyacetone + sulfite [RN:R12764]
Reaction(KEGG)
R12764
Substrate
(2S)-2,3-dihydroxypropane-1-sulfonate [CPD:C22383]
Product
hydroxyacetone [CPD:C05235];
sulfite [CPD:C00094]
Comment
The enzyme, characterized from the human gut bacterium Bilophila wadsworthia, 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.
