Evolution of enzymatic activities in the enolase superfamily: L-fuconate dehydratase from Xanthomonas campestris.

Biochemistry 45(49) , 14582-97, (2006)

Many members of the mechanistically diverse enolase superfamily have unknown functions. In this report we use both genome (operon) context and screening of a library of acid sugars to assign the L-fuc...

An enzyme from Saccharomyces cerevisiae which catalyzes the reaction: L-galactonolactone + O2 leads to L-ascorbate + H2O2 has been purified 466-fold from the mitochondrial fraction of a yeast homogena...
