| Comments |
Requires a divalent cation, preferably Mg2+, for activity [1]. The reaction involves an intramolecular skeletal rearrangement, with the bonds in?D-ribulose 5-phosphate that connect C-3 and C-5 to C-4 being broken, C-4 being removed as formate and reconnection of C-3 and C-5 [1]. The phosphorylated four-carbon product (L-3,4-dihydroxybutan-2-one 4-phosphate) is an intermediate in the biosynthesis of riboflavin [1]. |
