reteplase is a part of tissue plasminogen activator (t-pa) used for theremoval of thrombi in blood vessels. in the present study we express the reteplase genein escherichia coli top10 and then its thrombolytic activity was measured. the recombinant plasmid pbadgiiia was transformed into the competent escherichia coli top10 and then transformed bacteria was seeded into bioreactor containing 1.5 ...

In this work, we demonstrate that the fosI gene encodes a predicted small protein with 134 amino acids and determines reduced susceptibility to fosfomycin. It raised the MIC from 0.125 to 6 μg/ml when the pBRA100 plasmid was introduced into Escherichia coli TOP10 and to 16 μg/ml when the gene was cloned into the pBC_SK(-) vector and expressed in E. coli TOP10.

A new variant of the New Delhi metallo-enzyme (NDM) carbapenemase was identified in a multidrug-resistant Escherichia coli ST648 isolate recovered from the perineum and throat of a patient in the United Kingdom with a recent history of hospitalization in India. NDM-5 differed from existing enzymes due to substitutions at positions 88 (Val → Leu) and 154 (Met → Leu) and reduced the susceptibilit...

Enhanced Green Fluorescent Protein (eGFP) shows much stronger fluorescence than its ancestor, (GFP), thus has been widely applied as a reporter for biomedical research. In this study, we reported the expression of synthetic codon optimized gene encoding eGFP in Escherichia coli (E. coli). The was cloned into two vectors, pQE30 and pColdII resulting recombinant vectors were transformed E. M15 BL...

The pLysN plasmid containing the T7 lysozyme gene under control of the lac promoter was constructed to facilitate cell disintegration after expression of recombinant proteins in arabinose-induced expression systems. The usefulness of this plasmid was tested in Escherichia coli TOP10 and E. coli LMG194 cells carrying pBADMHADgeSSB plasmid containing Deinococcus geothermalis SSB protein gene unde...

background: production of tissue plasminogen activator protein (t-pa) in prokaryotes systems has many problems such as the lack of active protein production, multiple purification steps, and renaturation process which has been shown to be costly and time-consuming. methods: in this study, reteplase which is the nonglycosylated active domain of t-pa was used to transform top10 escherichia coli (...

Elevated levels of neutrophil elastase in CPOD (Chronic Obstructive Pulmonary Disease) airways are regarded as the main trigger lung destruction and inflammation. SLPI (Secretory leukocyte protease inhibitor), an inhibitor protease, represents attractive candidate for treatment chronic diseases due to proteases excess. The antiprotease active site has been located on C-terminal domain. This stu...
