Accepted name: formaldehyde transketolase
Reaction: D-xylulose 5-phosphate + formaldehyde = D-glyceraldehyde 3-phosphate + glycerone
Glossary: thiamine diphosphate = 3-[(4-amino-2-methylpyrimidin-5-yl)methyl]-5-(2-diphosphoethyl)-4-methyl-1,3-thiazolium
Other name(s): dihydroxyacetone synthase
Systematic name: D-xylulose-5-phosphate:formaldehyde glycolaldehydetransferase
Comments: A thiamine-diphosphate protein. Not identical with EC transketolase. Also converts hydroxypyruvate and formaldehyde into glycerone and CO2.
