Candida albicans produces a cystatin-type cysteine proteinase inhibitor.


A cysteine proteinase inhibitor was found in culture media of Candida albicans. Purification to homogeneity of the inhibitor was performed by carboxymethyl-papain-Sepharose affinity, DE-52 ion-exchange, and reverse-phase high performance liquid chromatographies. The purified inhibitor had an M(r) of 15 kDa and a pI of 4.9. It was more stable to heat and pH… (More)
