In a screen for Candida albicans genes encoding transactivating proteins, a pyruvate decarboxylase (EC 4.1.1.1.) regulator gene was isolated. An open reading frame (ORF) of 2511 bp was identified encoding a predicted protein of 836 amino acids with a molecular weight of 94·4 kDa. The protein showed glutamine‐ and proline‐rich stretches typical for transcriptional activators. The amino acid sequence comparisons between CaPdc2p of C. albicans and both Pdc2p of Saccharomyces cerevisiae and Rag3p of Kluyveromyces lactis , revealed similarities of 40% and 39%, respectively. The CaPDC2 gene was localized on chromosome 1. Southern blot analysis indicated that CaPDC2 might be a single copy gene. The growth defect of a S. cerevisiae pdc2Δ mutant on glucose was compensated by transformation of the C. albicans CaPDC2 gene. The EMBL Accession No. for the sequence reported in this paper is Y17007. Copyright © 1999 John Wiley & Sons, Ltd.
