Other name(s): | kdgF (gene name) | ||
Systematic name: | 4,5-unsaturated pyranuronate lyase (ring-opening) | ||
Comments: | The enzyme, found in bacteria and archaea, is involved in the degradation of polysaccharides such as alginate and pectin. The enzyme catalyses a pyranose ring-opening reaction followed by enol-keto tautomerization. | ||
