Type Ix Secretion System : Characterization Of An Effector Protein And An Insight Into The Role Of C-Terminal Domain Dimeration In Outer Membrane Translocation., Lahari Koneru
Electronic Theses and Dissertations
Porphyromonas gingivalis and Tannerella forsythia are two of the primary pathogens that are associated in the etiology and progression of chronic periodontitis. In T. forsythia, KLIKK proteases are the recently identified group of proteolytic enzymes that are secreted through Type IX secretion system (T9SS). Among, these KLIKK proteases a synergistic relationship was observed between karilysin and mirolysin in invading the host complement system for the survival of the bacteria. Since, karilysin has been already characterized, in this study we propose to study about mirolysin through structural, biochemical and biological characterization. The obtained results from the experiments has shown the …

This study investigates protein nucleic acid interactions between various proteins and G quadruplex (GQ) forming messenger RNAs (mRNAs) in human neurological disorders. GQ structures are formed in DNA/RNA, when four guanine residues form planar tetrads stabilized by Hoogsteen base pairing, that stack forming a GQ structure stabilized by potassium ions. These GQ structures are targeted by the arginine-glycine-glycine (RGG) repeat domain containing RNA-binding domain.
Three RGG domain containing RNA-binding proteins, all of which have been implicated in neurological disorders, and their interactions with GQ forming mRNAs, were investigated in this study: fused in sarcoma (FUS), fragile X mental retardation protein …
