چکیده

Two Aspergillus nidulans genes, xlnA and xlnB, encoding the X22 and X24 xylanases from this fungus, respectively, have been cloned and sequenced. Their cDNAs have been expressed in a laboratory Saccharomyces cerevisiae strain under the control of a constitutive yeast promoter, resulting in the construction of recombinant xylanolytic yeast strains.

CLONING AND EXPRESSION OF HUMAN IFNα2B GENE IN SACCHAROMYCES CEREVISIAE

Interferon is a protein secreted by eucaryotic cells following stimulation by viruses, bacteria, and many other immunogenes. Recent medical studies indicate that interferons have effective role in the treatment of virus infections, immunodeficiency and certain types of cancer such as hairy cell leukaemia (HCL). The aim of the present study is to apply yeast strain for secreting human IFNα2b fol...

EXPRESSION OF HEPATITIS B SURFACE ANTIGEN IN SACCHAROMYCES CEREVISIAE

The genome of HB V virus of serotype ayw cloned in pBR322 and expression shuttle vector p YES2 were used for construction of the HBsAg chimeric genes and their expression in Saccharomyces cerevisiae. Two recombinant plasmids were constructed. One of them contained the coding sequences for the major polypeptide of surface antigen. Another construct carried the major polypeptide with the pre-S2 a...

A gene from Aspergillus nidulans with similarity to URE2 of Saccharomyces cerevisiae encodes a glutathione S-transferase which contributes to heavy metal and xenobiotic resistance.

Aspergillus nidulans is a saprophytic ascomycete that utilizes a wide variety of nitrogen sources. We identified a sequence from A. nidulans similar to the glutathione S-transferase-like nitrogen regulatory domain of Saccharomyces cerevisiae Ure2. Cloning and sequencing of the gene, designated gstA, revealed it to be more similar to URE2 than the S. cerevisiae glutathione S-transferases. Howeve...

Isolation, Subtype Determination, Cloning and Expression of HBsAg Gene from an Iranian Carrier in Saccharomyces cerevisiae

The Hepatitis B Surface antigen ( HBsAg) gene was isolated from an Iranian HBeAg positive carrier by PCR. The gene was cloned in pUC19 for sequencing and pYES2 for expression in Saccharomyces cerevisiae, which pNF1 and pDF3 constructs were made respectively. The sequencing data showed that the isolated HBsAg gene shared more than 90% homology with the ayw subtype. The pDF3 was transferred into ...

Depletion of ε-COP in the COPI Vesicular Coat Reduces Cleistothecium Production in Aspergillus nidulans

We have previously isolated ε-COP, the α-COP interactor in COPI of Aspergillus nidulans, by yeast two-hybrid screening. To understand the function of ε-COP, the aneA (+) gene for ε-COP/AneA was deleted by homologous recombination using a gene-specific disruption cassette. Deletion of the ε-COP gene showed no detectable changes in vegetative growth or asexual development, but resulted in decreas...
