We describe the cloning and expression of a new cDNA from the filamentous fungus Aspergillus clavatus IFO 8605. This cDNA contains an open reading frame (ORF) that predicts a putative ribonuclease precursor with high similarity to the alpha-sarcin family of ribosome-inactivating proteins (RIPs). The cDNA encoding the mature protein was expressed in(More)
The present paper describes two immunoconjugates consisting of an anti-epidermal growth factor receptor (EGFR) monoclonal antibody (MAb), named Mint5, covalently linked to the type 1 ribosome-inactivating proteins (RIPs) ocymoidine (Ocy) and pyramidatine (Pyra) from Saponaria ocymoides and Vaccaria pyramidata respectively. Both antibody and toxins are shown(More)
The goal of the present study was to establish the condition to obtain preparative amounts of the recombinant cytotoxin alpha-sarcin to be used for immunoconjugate production. alpha-Sarcin cDNA was isolated from Aspergillus giganteus strain MDH 18,894 and its expression in Escherichia coli was attempted by the use of both two-cistron and fusion(More)
It is known that under some circumstances DNA sequences made up of purine and pyrimidines in repeated alternation can undergo a transition from the right-handed to a left handed helical configuration which has been called Z-DNA. We have analyzed yeast chromosomal DNAs for the presence of alternating purine-pyrimidine stretches using a new strategy. Our(More)
Murine antibodies which recognize the epidermal growth factor receptor (EGF-r) are good candidates for therapy and diagnosis of tumors overexpressing this receptor. Here we report the isolation of the variable regions from a murine monoclonal antibody anti-EGF-r (Mint5), the procedure to obtain the mouse/human chimeric antibody (chMint5) and its expression(More)
We generated a recombinant immunotoxin, named scFv(MGR6)-Cla, composed of the Fv region of an anti ErbB2 monoclonal antibody (MGR6) fused to clavin, a type 1 ribosome-inactivating protein (RIP) from Aspergillus clavatus. ErbB2 is a tyrosine kinase receptor which is overexpressed in most adenocarcinomas; clavin is a 17 kDa ribonuclease which inhibits protein(More)
Chromosomal DNA molecules from the plant pathogenic fungus Phoma tracheiphila were separated by orthogonal-field-alternation gel electrophoresis (OFAGE). Intact chromosomal DNA was obtained by a protocol which involves embedding fungal hyphae in low-gelling agarose followed by enzymatic digestion of the cell wall and subsequent lysis of the other cell(More)
