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]. |
