Cloning and Characterization of a Promoter

Analysis of SFL1 and SFL2 Promoter Region in Arabidipsis thaliana using Gateway Cloning System

SFL1 and SFl2 (SETH Four Like) genes are two members of SETH4 gene family in Arabidopsis thaliana expressed in saprophytic tissues. In this study, expression of SFL1 and SFL2 genes were studied using Gateway Cloning Technology. Primers were designed for PCR amplification of promoter region of SFL1 (900 bp) and SFL2 (930 bp) genes having attB1 recombination sites using Kod Hi Fi DNA polymerase e...

MOLECULAR CLONING AND EVALUATION OF WILD PROMOTER IN EXPRESSION OF BACILLUS SPHAERICUS PHENYLALANINE DEHYDROGENASE GENE IN BACILLUS SUBTILIS CELLS

To evaluate the role of wild promoter of L-phenylalanine dehydrogenase (PheDH) gene, referred to as pdh, from Bacillus sphaericus in expression, cloning of pdh gene in Bacillus subtilis was performed. The whole pdh gene was cloned in pHY300PLK shuttle vector and amplified, construct (pHYDH) then transformed in B. subtilis ISW1214 and E. coli JM109. The pdh endogenous promoter presented no effec...

THE GENE CLONING, OVEREXPRESSION, PURIFICATION, AND CHARACTERIZATION OF DIBENZOTHIOPHENE MONOOXYGENASE AND DESULFINASE FROM GORDONIA ALKANIVORANS RIPI90A

The biodesulfurization (BDS) of sulfur compounds in fossil fuels is a process to reduce sulfur dioxide emissions that cause environmental pollution. Gordonia alkanivorans RIPI90A is able to convert dibenzothiophene, an organic sulfur compound in petroleum, to 2-hydroxybiphenyl (2-HBP) in 4S pathway. In this study, (DBT), DszA and DszB, DBT sulfone monooxygenase, and desulfinase were respectivel...

Detection, Cloning, Molecular Characterization and Phylogenic Analyses of a New Primate T-Cell Lymphotropic Virus Type I in Olive Baboon

CLONING AND EXPRESSION OF A HUMAN INTERFERON a2 GENE IN E. COLI

The plasmid pALCA1SIFN containing cDNA that encodes the human interferon a-2b was obtained from the ATCC(no. 531667). In this system the expression of the gene is under the control of an alcA promoter. alcA p is a specific promoter for expression of different genes in Aspergillusfilamentous. In this plasmid the coding region of IFN?-2b is preceded by the coding region of a synthetic signal ...

Molecular Cloning and Characterization of a Lipase from an Indigenous Bacillus pumilus

Cloning and sequencing of a lipase gene from an indigenous Bacillus pumilus, strain F3, revealed an open-reading frame of 648 nucleotides predicted to encode a protein of 215 residues. Sequence analysis showed that F3 lipase contained a signal peptide composed of 34 amino acids with an H domain of 18 residues. A tat-like motif was found in the signal peptide similar to some other Bacillus pumil...
