LITERATURE
DNA and amino acid sequence determination and analysis of wild-type and mutant strains
-
DNA is extracted from extraradial mycelium growing around Cichorium intybus, PCR-amplification, cloned into pGEM-T Vector System for sequencing, for complementation assay in Saccharomyces cerevisiae mutant erg25-25c (methyl oxidase deficient) the GintSMO gene is amplified and cloned into the NotI-linearized yeast expression vector pFL61
gene Pcerg25A, DNA and amino acid sequence determination and analysis, Pcerg25A is located in the DNA region containing the penicillin gene cluster, and thus its copy number is dependent on the patterns of the cluster region, up to eight copies of Pcerg25A are found in the high-productivity strain NCPC 10086, functional complementation of the erg25-deficient Saccharomyces cerevisiae strain ATCC 4024690, subcloning in Escherichia coli strain DH5alpha, phylogenetic analysis, overview
gene Pcerg25B, DNA and amino acid sequence determination and analysis, Pcerg25B is present in just a single copy in Penicillium chrysogenum genomes, functional complementation of the erg25-deficient Saccharomyces cerevisiae strain ATCC 4024690, subcloning in Escherichia coli strain DH5alpha, phylogenetic analysis, overview
