(2010-08-25)The genus Salmonella includes facultative intracellular pathogens. Salmonella enterica serovar Typhi (S. Typhi) causes typhoid fever in humans killing about 2,00,000 people globally every year. Salmonella enterica serovars ... -
Cell Survival Strategies : Role Of Gyrase Modulatory Proteins
(2010-07-21)A steady state level of negative supercoiling is essential for chromosome condensation, initiation of replication and subsequent elongation step. DNA gyrase, found in every eubacteria, serves the essential housekeeping ... -
Translational Control Of p53 And Its Isoform By Internal Initiation
(2010-07-19)Tumor suppressor p53, the guardian of the genome, has been intensely studied molecule owing to its central role in maintaining cellular integrity. While the level of p53 protein is maintained low in unstressed conditions, ... -
New Active Site Fold And The Role Of Metal Ions In Structure Function Relationship Of A Promiscuous Endonuclease - R.KpnI
(2010-07-08)Bacteria employ survival strategies to protect themselves against foreign invaders, including bacteriophages. The ‘immune system’ of bacteria relies mostly on restriction-modification (R-M) systems. The primary role of R-M ... -
