ENZYME entry: EC 4.2.99.25

Accepted Name
unsaturated pyranuronate lyase
Reaction catalysed
4-deoxy-L-erythro-hex-4-enopyranuronate = (4S,5S)-4,5-dihydroxy-2,6-dioxohexanoate 4-deoxy-L-threo-hex-4-enopyranuronate = 5-dehydro-4-deoxy-D-glucuronate
Comment(s)
The enzyme, found in bacteria and archaea, is involved in the degradation of polysaccharides such as alginate and pectin. The enzyme catalyzes a pyranose ring-opening reaction followed by enol-keto tautomerization.
