Periplasmic nonspecific acid phosphatase II from Salmonella typhimurium LT2. Crystallization, detergent reactivation, and phosphotransferase activity.
The periplasmic nonspecific acid phosphatase II from Salmonella typhimurium was purified to homogeneity from a mutant strain that overproduces the enzyme (Uerkvitz, W., and Beck, C.F. (1981) J. Biol. Chem. 256, 382-389). It was shown that the enzyme transfers phosphate groups from organic phosphoric acid esters (donors) to water as well as to the 2'-, 3'-, or 5'-hydroxyls of nucleosides, nucleo...
متن کاملThe reversible dissociation of the alkaline phosphatase of Escherichia coli. I. Formation and reactivation of subunits.
Current investigations of protein structure reveal that an increasing number of enzymes occur in their native state as organized aggregates of polypeptide chains (1, 2). Although it has long been known that some proteins are composed of subunits, the extent and significance of this feature of protein structure has only been recently recognized. For example, it now appears that the mechanism of ...
متن کاملp53 reactivation
Lack of p53 expression or expression of mutant p53 is common in human cancers and is associated with increased tumor growth and resistance to therapies. Significant efforts toward pharmaceutical reactivation of defective p53 by small molecules are therefore underway, targeting the different means that inactivate p53. Indeed, reactivated p53 can lead to tumor destruction. A recent paper in Cance...
متن کاملProline isomerization is unlikely to be the cause of slow annealing and reactivation during the folding of alkaline phosphatase.
The in vitro folding of Escherichia coli alkaline phosphatase (AP) from the guanidine hydrochloride (GdnHCl) denatured state is characterized by a significant slow phase in the post activational recovery of native protein lability (probed by the susceptibility to GdnHCl denaturation and occurring on the time scale of days) as well as a slow phase in the recovery of activity (on the time scale o...
متن کاملCovid-19 Vaccination and Reactivation of Varicella Zoster Virus
Introduction: After COVID-19 pandemic in 2020 that mostly affects upper respiratory tract, the scientists investigated an effective vaccine against the virus. As the vaccination of general population started some patients were visited with varicella zoster virus activation following the COVID vaccine.
