Q12GE3  (Q12GE3_POLSJ) -  Galactarate dehydratase / L-talarate dehydratase from Polaromonas sp. (strain JS666 / ATCC BAA-500)

Seq: 383 a.a.

Struc: 363 a.a.

Enzyme reactions

• Enzyme class 1: E.C.4.2.1.- - ?????
• Enzyme class 2: E.C.4.2.1.42 - galactarate dehydratase.
• Reaction: galactarate = 5-dehydro-4-deoxy-D-glucarate + H2O

Note, where more than one E.C. class is given (as above), each may correspond to a different protein domain or, in the case of polyprotein precursors, to a different mature protein.
