Bacterial Expression and Functional Characterization of A Naturally Occurring Exon6-less Preprochymosin cDNA

Chymosin (Rennin EC 3.4.23.4), an aspartyl proteinase, is the major proteolytic enzyme in the fourthstomach of the unweaned calf, and it is formed by proteolytic activation of its zymogene, prochymosin.Following the cloning of synthesized cDNAs on mRNA pools extracted from the mucosa of the calf fourthstomach, we have identified an alternatively spliced form of preprochymosin ...

Production and functional characterization of human insulin-like growth factor 1

Insulin-like growth factor 1 (IGF-1) is a polypeptide hormone produced mainly by the liver in response to the endocrine growth hormone (GH) stimulus. This protein is involved in a wide range of cellular functions, including cellular differentiation, transformation, apoptosis suppression, migration and cell-cycle progression and other metabolic processes. In the current study, human heart cDNA w...

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...

Cloning and Characterization of cbhII Gene fromTrichoderma parceramosum and Its Expressionin Pichia pastoris

The genomic and cDNA clones encoding cellobiohydrolase II (CBHII) have been isolated and sequenced from a native Iranian isolate of Trichoderma parceramosum, a high cellulolytic enzymes producer isolate. This represents the first report of cbhII gene from this organism. Comparison of genomic and cDNA sequences indicates this gene contains three short introns and also an open reading frame codin...

Affinity Purification and Characterization of Recombinant Bacillus sphaericus Phenylalanine Dehydrogenase Produced by pET Expression Vector System

Cloning and expression of the L-phenylalanine dehydrogenase gene, from B. sphaericus in E. coli were done. The gene was cloned in the vector pET16b and transformed into E. coli BL21 (DE3). The functional form of the L-phenylalanine dehydrogenase enzyme was purified by affinity purification techniques, taking advantage of the ability of this enzyme to bind to the nucleotide site affinity dye, Re...
