Cloning, Expression, And Activity Analysis Of Human Cathepsin C In The Yeast Pichia Pastoris, Cenk Dağlioğlu
Cloning, Expression, And Activity Analysis Of Human Cathepsin C In The Yeast Pichia Pastoris, Cenk Dağlioğlu
Turkish Journal of Biology
The yeast Pichia pastorisexpression system was investigated for the production of human cathepsin C (CatC) recombinant protein. The full-length CatC cDNA, corresponding to amino acids 12-475, was synthesized from interleukin-2 (IL-2) stimulated human peripheral blood mononuclear cells and subcloned in the pGEM-T cloning vector. After confirming the DNA sequence of the insert, the gene was cloned into the pPICZ\alphaA expression vector under the control of the methanol-inducible alcohol oxidase (AOX1) promoter and transformed to P. pastoris X-33 cells. The expressed protein was secreted into the culture medium through the alpha-factor mating signal sequence of the expression vector. Analysis of the …

Characterization Of Proteinase Inhibitor-Ii Gene Under Osrglp2promoter For Salt Stress In Transgenic Nicotiana Benthamiana, Shazia Rehman, Bodil Jørgensen, Soren Rasmussen, Tariq Mahmood
Turkish Journal of Biology
Proteinase inhibitors in plants are mainly involved in conferring resistance against herbivores and pathogens. However, their role in abiotic stress resistance has also been reported. Therefore, transgenic tobacco plants were generated constitutively expressing the tomato proteinase inhibitor-II (PI-II) under control of the rice root germin-like protein 2 (OsRGLP2) promoter using Agrobacterium tumefaciens. T1 transgenic seedlings were subjected to stress treatments with different concentrations of sodium chloride (NaCl) (100 mM, 200 mM, 300 mM). Quantitative real-time PCR revealed considerable levels of expression and upregulation of PI-II in transgenic lines under salt stress. Considering the phenotypic effects, the transgenic seedlings showed better …
