IUBMB Enzyme Nomenclature


Accepted name: glycerol dehydratase

Reaction: glycerol = 3-hydroxypropanal + H2O

Other name(s): glycerol dehydrase; glycerol hydro-lyase

Systematic name: glycerol hydro-lyase (3-hydroxypropanal-forming)

Comments: Two different forms of the enzyme have been described. One form requires a cobamide cofactor, while the other is a glycyl radical enzyme.
