1JPM, 1JPD - PubMed Abstract: 
The members of the enolase superfamily catalyze different overall reactions, yet share a partial reaction that involves Mg(2+)-assisted enolization of the substrate carboxylate anion. The fate of the resulting enolate intermediate is determined by the active site of each enzyme ...
