Sensing of DNA modifications by pAgo proteins in  vitro
Biochimie. 2023 Dec 19;220:39-47. doi: 10.1016/j.biochi.2023.12.006. Online ahead of print.ABSTRACTMany prokaryotic Argonaute (pAgo) proteins act as programmable nucleases that use small guide DNAs for recognition and cleavage of complementary target DNA. Recent studies suggested that pAgos participate in cell defense against invader DNA and may also be involved in other genetic processes, including DNA replication and repair. The ability of pAgos to recognize specific targets potentially make them an invaluable tool for DNA manipulations. Here, we demonstrate that DNA-guided DNA-targeting pAgo nucleases from three bacteri...

Effects of osmolytes under crowding conditions on the properties of muscle glycogen phosphorylase b
Biochimie. 2023 Dec 20;220:48-57. doi: 10.1016/j.biochi.2023.12.005. Online ahead of print.ABSTRACTThe study of the relationship between the activity and stability of enzymes under crowding conditions in the presence of osmolytes is important for understanding the functioning of a living cell. The effect of osmolytes (trehalose and betaine) on the secondary and tertiary structure and activity of muscle glycogen phosphorylase b (Phb) under crowding conditions created by PEG 2000 and PEG 20000 was investigated using dynamic light scattering, differential scanning calorimetry, circular dichroism spectroscopy, fluorimetry and ...

Present study provides insights into the mechanism underlying the MVK-induced entry of L. donovani and improve our knowledge of host-pathogen interactions. We have discussed Mevalonate kinase (MVK)-induced actin reorganization, modulation of signalling pathways and host cell functions. Our results show that LdMVK gains access to macrophage cytosol and induces actin ...
