Purification of native enolase from medically important Candida species

The 48 kDa glycolytic enzyme, enolase, has been identified as an immunodominant antigen in Candida albicans infections. It has also been identified as an important fungal allergen. Enolase from a number of medically important Candida species has been purified using a two-step anion- and cation-exchange chromatography method that was preceded by an organic extraction. The enolases purified by this method have a high specific activity and the procedure is 40% efficient, with an average of 5 mg of enolase/g of Candida cells. The purification of native enolase from medically important Candida species will enable the immunological significance and interspecies relationships of this major fungal antigen to be investigated.
