Protein existence	Inferred from homology

General annotation (Comments)

Function	Involved in the cleavage of the C1-C2 bond of 3D-(3,5/4)-trihydroxycyclohexane-1,2-dione (THcHDO) to yield 5-deoxy-glucuronate (5DG) By similarity. HAMAP MF_01669
Catalytic activity	3,5/4-trihydroxycyclohexa-1,2-dione + H2O = 5-deoxy-glucuronic acid. HAMAP MF_01669
Cofactor	Binds 1 magnesium ion per subunit By similarity. HAMAP MF_01669 Binds 1 thiamine pyrophosphate per subunit By similarity.
Pathway	Polyol metabolism; myo-inositol degradation into acetyl-CoA; acetyl-CoA from myo-inositol: step 3/7. HAMAP MF_01669
Sequence similarities	Belongs to the TPP enzyme family.
Sequence caution	The sequence ABP57765.1 differs from that shown. Reason: Erroneous initiation.
