Biochemical Characterization Of An Acid-Adaptive Type III DNA Methyltransferase From Helicobacter Pylori 26695 And Its Biological Significance
(2014-12-15)Enzyme DNA methylation is an important biochemical process that imprints DNA with additional information. DNA methylation is catalyzed by S-adenosyl-L-methionine (AdoMet)-dependent methyltraferases (MTases). Prokaryotic ... -
Characterization Of HP1369-HP1370 From Helicobacter Pylori : A Novel ε Type N6 –Adenine Methyltransferase
(2013-07-18)Helicobacter pylori is one of the most genetically diverse bacterial species that successfully colonizes at least 50% of the world population. It has been associated with humans for thousands of years and most probably ... -
Exploring the Roles of Phase Variable HpyAII Restriction-modification System in the Human Pathogen Helicobacter pylori
Helicobacter pylori is a Gram-negative microaerophilic bacteria known to infect as much as 80% of some populations with an average morbidity range of around 50% of the world population. It has been recognized as a definitive ... -
Functional Analysis Of Unique Motifs In Dimeric EcoP151 DNA Methyltransferase
(2011-01-11)Restriction endonucleases occur ubiquitously among bacteria, archaea and in viruses of certain unicellular algae, and they are usually accompanied by a modification enzyme of identical specificity; together, the two ... -
Helicobacter Pylori Restriction-Modification Systems : Possible Roles Beyond Genome Protection
(2013-06-06)Helicobacter pylori is one of the most potential and successful human pathogen which colonizes atleast 50% of world population. One of the important characteristics of this pathogen is the degree of allelic diversity and ... -
Insights Into Transcription-Repair Coupling Factor From Mycobacterium Tuberculosis
(2014-12-01)Introduction Nucleotide excision repair (NER) is a highly conserved pathway involved in repair of a wide variety of structurally unrelated DNA lesions. One of the well characterized NER systems is from E. coli which ... -
Kinetic, Catalytic and Epigenetic Properties of HpyAXVII DNA Methyltransferase – a Phasevarion in the Human Pathogen Helicobacter pylori
Helicobacter pylori is the leading cause of gastric cancer in human beings. It is a helix-shaped, Gram-negative, motile bacteria that colonizes the gastric mucosa and eventually the gastric epithelium. It has an overabundance ... -
Structural and Biochemical Analysis of DNA Processing Protein A (DprA) from Helicobacter Pylori
(2018-05-09)H. pylori has a panmictic population structure due to high genetic diversity. The homoplasy index for H. pylori is 0.85 (where 0 represents a completely clonal organism and 1.0 indicates a freely recombining organism) which ... -
Studies On DNA Mismatch Repair Nicking Endonucleases Of Haemophilus Influenzae And Neisseria Gonorrhoeae
(2010-01-01)DNA mismatch repair ensures faithful transmission of genetic material from parents to progeny, which is required for the survival of the organism. The studies on E. coli MMR proteins have formed the basis for the study ... -
Untangling the Helicobacter pylori genome: Deciphering the significance of zinc finger motif(s) in Topoisomerase I catalysis
Helicobacter pylori, a human pathogen dominating gastric microbial population, displays differential gene expression during various stages of stomach colonization. Topoisomerases play a crucial role in maintaining DNA ...
