Regulation of Flagellar Motility in Giardia lamblia and Trichomonas vaginalis
Protozoan pathogens are responsible for infections that are highly prevalent, especially in developing and under-developed countries. Flagellar motility is exhibited by a variety of organisms ranging from bacteria to certain ...
Studies on the roles of rffG and rfbB encoding dTDP-glucose 4,6- dehydratase in Salmonella Typhimurium
Salmonellosis is a major health concern which causes significant morbidity and mortality worldwide. Infection with Salmonella Typhimurium leads to self-limiting diarrhea in healthy individuals and invasive disease in ...
Roles of Protein Acetylation in the Human Pathogen Helicobacter pylori
Helicobacter pylori is a gram-negative epsilon proteobacterium infecting half of the world population. H. pylori is a naturally competent bacterium with a huge repertoire of Restriction-Modification (RM) systems. The ...
The dual-targeting of Saccharomyces cerevisiae Pso2 into the nucleus and mitochondria is regulated by post-translational modifications: Implications for organelle-specific DNA repair
The repair of DNA interstrand crosslinks (ICLs) involves the concerted action of multiple DNA repair pathways. In eukaryotes, ICLs are sensed and repaired by replication-coupled or replication-independent mechanisms in ...
Understanding the Long-term Impact and Mechanism of Action of Endosulfan, an Organochlorine Pesticide on Fertility, Development and Growth of Mice
Endosulfan (ES) is one of the major broad-spectrum organochlorine pesticides
categorized as Class II (moderately hazardous) by WHO and Class I (highly acutely toxic) by
US Environment Protection Agency. Although the use ...
Understanding Nonhomologous DNA End Joining: Novel Insights Into Mechanism and Regulation
This study has provided new insights into the mechanistic details of NHEJ
and showed that DNA sequence around the break site can be a factor in determining which
proteins involved in NHEJ might be recruited with a higher ...
Mechanistic Insights Into Heat Shock Protein 90 (Hsp90) Trans-splicing in Giardia lamblia
Hsp90 gene is conserved and encoded by a single ORF with none to many cis-spliced introns across the biological kingdom. Previous studies from our lab have shown that Hsp90 gene in Giardia lamblia has a split nature having ...
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 ...
Determination of significance of SUMOylation of the Smc5/6 complex
The fascination of scientists to the Smc5/6 complex began in the 1990s, with the characterization of UV and γ radiation-sensitive rad18 mutant and its identification as a component of a novel Structural Maintenance of ...
Biochemical characterization of UvrD helicase and its 1 interplay with DNA mismatch repair proteins in 2 Neisseria gonorrhoeae
UvrD helicase belongs to type I superfamily of helicases. It participates in Nucleotide Excision Repair (NER) and DNA Mismatch Repair (MMR). It also participates in the rolling circle replication. It has been shown that ...
