Proteome analysis of the penicillin producer Penicillium chrysogenum: characterization of protein changes during the industrial strain improvement.
Proteomics is a powerful tool to understand the molecular mechanisms causing the production of high penicillin titers by industrial strains of the filamentous fungus Penicillium chrysogenum as the result of strain improvement programs. Penicillin biosynthesis is an excellent model system for many other bioactive microbial metabolites. The recent publication of the P. chrysogenum genome has esta...
متن کاملPenicillin acyltransferase in Penicillium chrysogenum.
Isotopic exchange of (35)S between penicillins and 6-amino-penicillanic acid (6-APA) was observed in cell-free extracts of Penicillium chrysogenum. Sulfhydryl-containing compounds were required for activity. Dithiothreitol, dithioerythritol, mercaptoethanol, and glutathione served as activators. The acyltransferase was purified threefold by adsorption on calcium phosphate gel at pH 6 and elutio...
متن کاملEvidence for Dicer-dependent RNA interference in the industrial penicillin producer Penicillium chrysogenum.
RNA interference (RNAi) is a sequence-specific post-transcriptional gene silencing system that downregulates target gene expression. Here, we provide several lines of evidence for RNA silencing in the industrial beta-lactam antibiotic producer Penicillium chrysogenum using the DsRed reporter gene under the control of the constitutive trpC promoter or the inducible xylP promoter. The functional ...
متن کاملProteomics Shows New Faces for the Old Penicillin Producer Penicillium chrysogenum
Fungi comprise a vast group of microorganisms including the Ascomycota (majority of all described fungi), the Basidiomycota (mushrooms or higher fungi), and the Zygomycota and Chytridiomycota (basal or lower fungi) that produce industrially interesting secondary metabolites, such as β-lactam antibiotics. These compounds are one of the most commonly prescribed drugs world-wide. Since Fleming's i...
متن کاملSulfate utilization by penicillin-producing mutants of Penicillium chrysogenum.
A great deal of work has been directed toward increasing the yield of penicillin in fermentations with Penicillium chrysogenum. The spectacular increase in yield which has been achieved has resulted, in the main, from two approaches. In the first approach, mutant strains of P. chrysogenum produced by spontaneous variation or by the action of mutagenic agents such as nitrogen mustard or ultravio...
