Cloning and expression of a synthetic gene for Cerebratulus lacteus neurotoxin B-IV

Structure and action of heteronemertine polypeptide toxins. Amino acid sequence of Cerebratulus lacteus toxin B-II and revised structure of toxin B-IV.

The primary structure of Cerebratulus lacteus toxin B-II has been investigated by automated Edman degradation of the reduced, carboxymethylated protein and of tryptic peptides derived from the maleylated protein. As a result of these studies, the identity of all 55 amino acid residues in the polypeptide chain has been unambiguously determined. Hydroxyproline, an amino acid not normally found in...

Cloning and Expression of Thermus Aquaticus DNA Polymerase Gene, Using a Thermo-Inducible Expression Vector

DNA polymerase gene from Thermus aquaticus strain YT1 was amplified using VENTTM DNA po-lymerase and cloned under the control of X.PR promoter and expression was induced by a shift in tern perature. The culture was then sonicated, and after centrifugation the lysate was treated with poly‌ethyleneimine followed by a salting-out step. Finally the protein was precipitated with ammonium sulfate and...

Cloning and Expression of Recombinant Helicobacter pylori Urease A and B Subunits as a Putative Vaccine

Helicobacter pylori infection is among the most prevalent infections in the world involving more than half the adult population. H. pylori infection results in active chronic gastritis, peptic ulcers and enhances the risk of gastric malignancies. It is of utmost importance to prevent H. pylori infection particularly in highly prevalent countries including Iran. The urease holoenzyme produced by...

Cloning and Expression Analysis of ZmERD3 Gene From Zea mays

Background: Stresses (such as drought, salt, viruses, and others) seriously affect plant productivity. To cope with these threats, plants express a large number of genes, including several members of ERD (early responsive to dehydration) genes to synthesize and assemble adaptive molecules. But, the function of ERD3 gene hasn’t been known so far.Objectives:</strong...
