IUBMB Enzyme Nomenclature


Accepted name: L-talarate dehydratase

Reaction: L-altarate = 5-dehydro-4-deoxy-D-glucarate + H2O

Glossary: L-altrarate = L-talarate = (2R,3R,4S,5R)-2,3,4,5-tetrahydroxyhexanedioate

Other name(s): L-talarate hydro-lyase

Systematic name: L-altarate hydro-lyase (5-dehydro-4-deoxy-D-glucarate-forming)

Comments: Requires Mg2+. The enzyme, isolated from the bacteria Salmonella typhimurium and Polaromonas sp. JS666, also has activity with galactarate (cf. EC, galactarate dehydratase).
