EC Tree
IUBMB Comments The enzyme catalyses the reaction in the direction of producing (5-formylfuran-3-yl)methyl phosphate, an intermediate in the biosynthesis of methanofuran. The sequence of events starts with the removal of a phosphate group, followed by aldol condensation and cyclization. Methanofuran is a carbon-carrier cofactor involved in the first step of the methanogenic reduction of carbon dioxide by methanogenic archaea.
The expected taxonomic range for this enzyme is: Bacteria, Archaea, Eukaryota

2 D-glyceraldehyde 3-phosphate = (5-formylfuran-3-yl)methyl phosphate + phosphate + 2 H2O
a phosphate elimination reaction and a triose phosphate isomerase-like reaction occur at the glyceraldehyde 3-phosphate binding site I and II, respectively, prior to the aldol condensation between the enzyme-bound enol form of methylglyoxal and dihydroxyacetone phosphate, after which the catalytic cycle is completed by a cyclization and two dehydration reactions assisted by several general acids/bases at the same active site
