4.2.1.30

Accepted name:

glycerol dehydratase

Reaction:

glycerol = 3-hydroxypropanal + H₂O

Other name(s):

glycerol dehydrase; glycerol hydro-lyase; dhaB (gene name)

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.
