C-terminal domain of CagX is responsible for its interaction with CagT protein of Helicobacter pylori type IV secretion system.

Helicobacter pylori are the well known human pathogen associated with gastric cancer and peptic ulcer. Pathogenesis is mainly due to the presence of 40 kb cagPAI (cag Pathogenicity Island) region that encodes the type IV secretion system (TFSS) consisting of a cytoplasmic part, a middle part/core complex (spans from inner membrane to outer membrane), and an outer membrane associated part. CagX and CagT are two important proteins of TFSS that have homology with virB9 and virB7 of Agrobacterium tumefaciens TFSS.

Molecular characterization and polyclonal antibody generation against core component CagX protein of Helicobacter pylori type IV secretion system.

Gram-negative bacteria Helicobacter pylori cause gastric ulcer, duodenal cancer, and found in almost half of the world's residents. The protein responsible for this disease is secreted through type IV secretion system (TFSS) of H. pylori.

Strategies for the production of recombinant protein in Escherichia coli.

In the recent past years, a large number of proteins have been expressed in Escherichia coli with high productivity due to rapid development of genetic engineering technologies. There are many hosts used for the production of recombinant protein but the preferred choice is E. coli due to its easier culture, short life cycle, well-known genetics, and easy genetic manipulation.

Vitamin-C as anti-Helicobacter pylori agent: More prophylactic than curative- Critical review.

Potential of nonantibiotic therapies for treatment of Helicobacter pylori-related acid peptic disease remains underexplored. Several clinical studies have shown that higher prevalence of H. pylori infection is associated with low Vitamin C (Vit C) level in serum and gastric juice.
