Single copies of the transposon Restless from Tolypocladium inflatum were introduced into Neurospora crassa and Penicillium chrysogenum. Excision of Restless from its donor site was investigated in N. crassa and in P. chrysogenum using direct selective conditions. In N. crassa, forward selection was also analyzed. Deleted Restless elements were frequently obtained in addition to the expected co...
The filamentous fungus Penicillium chrysogenum harbors an astonishing variety of nonribosomal peptide synthetase genes, which encode proteins known to produce complex bioactive metabolites from simple building blocks. Here we report a novel non-canonical tetra-modular nonribosomal peptide synthetase (NRPS) with microheterogenicity of all involved adenylation domains towards their respective sub...
The present study was aimed at exploring the native wild isolates of Penicillium chrysogenum series in terms of their penicillin production potential. Apart from the standard medium, the efforts were made to utilize suitable agro-industrial wastes for the maximum yield of penicillin. Two series of P. chrysogenum were isolated from local sources and named as P. chrysogenum series UAF R1 and P. c...
We have isolated the Penicillium chrysogenum pex5 gene encoding the receptor for microbody matrix proteins containing a type 1 peroxisomal targeting signal (PTS1). Pc-pex5 contains 2 introns and encodes a protein of approximately 75 kDa. P. chrysogenum pex5 disruptants appear to be highly unstable, show poor growth, and are unable to sporulate asexually. Furthermore, pex5 cells mislocalize a fl...
This paper is the second of a series dealing with the analysis of penicillin by means of a chromatogram using solvent-phosphate buffer partition on a silica base. The first paper (Levi, 1948) described the development of this type of chromatogram which is based on that ofMartin & Synge (1941), and outlined the principles of its application to the study of penicillin. The work described was carr...
