IntEnz Enzyme Nomenclature
EC 4.2.3.153

Names

Accepted name:
(5-formylfuran-3-yl)methyl phosphate synthase
Other names:
mfnB (gene name)
4-HFC-P synthase
2-furaldehyde phosphate synthase
Systematic name:
D-glyceraldehyde-3-phosphate phosphate-lyase [D-glyceraldehyde-3-phosphate-adding (5-formylfuran-3-yl)methyl-phosphate-forming]

Reaction

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. Formerly EC 4.1.99.21.
