Sysname
(S)-4-hydroxy-2-oxohexanoate pyruvate-lyase (propanal-forming)
Reaction(IUBMB)
(S)-4-hydroxy-2-oxohexanoate = propanal + pyruvate
Reaction(KEGG)
Substrate
(S)-4-hydroxy-2-oxohexanoate
Product
Comment
Requires Mn2+ for maximal activity [1,2]. The enzymes from the bacteria Burkholderia xenovorans and Thermus thermophilus also perform the reaction of EC
4.1.3.39 , 4-hydroxy-2-oxovalerate aldolase [1,2,6]. The enzyme forms a bifunctional complex with EC
1.2.1.87 , propanal dehydrogenase (CoA-propanoylating), with a tight channel connecting the two subunits [3,4,6].
History
EC 4.1.3.43 created 2013
