The yeast Candida boidinii PEP4 and PRB1 genes, encoding proteinase A (PrA) and proteinase B (PrB), respectively, have been cloned and their primary structures were analyzed. The open reading frames of the PEP4 gene (1263 bp encoding a protein of 420 amino acids) and the PRBI gene (1683 bp encoding a protein of 560 amino acids) were found. The deduced amino acid sequences of PrA and PrB are very similar to Saccharomyces cerevisiae PrA and PrB (64% and 61% identities, respectively). Both PEP4 and PRBI genes were disrupted in the C. boidinii genome by one-step gene disruption. The resultant pep4delta and the pep4delta prb1delta strains lost protease activity when compared with the wild-type original strain. The constructed C. boidinii strains are expected to be useful hosts for heterologous protein production.
