A multicopper oxidase gene from : cloning, characterization and disruption Free

Abstract

A multicopper oxidase gene from the human pathogenic yeast was isolated and characterized. An open reading frame of 1872 bp, designated , was identified, encoding a predicted protein of 624 amino acids and a molecular mass of 705 kDa. The identity between the deduced amino acid sequences of and the gene is 55%. was localized on chromosome 6. A null mutant (Δ/Δ) was constructed by sequential gene disruption. Unlike the SC5314 wild-type strain the Δ mutant was unable to grow in low-iron medium. The lack of growth of a Δ mutant in iron-limited medium was compensated by transformation with . The null mutant strain showed no change in pathogenicity compared with the wild-type strain in the mouse model of systemic candidiasis.
