Discovery and characterization of a thermostable bacteriophage RNA ligase homologous to T4 RNA ligase 1.

abstract：:Many nucleic acid-binding proteins and the AAA+ family form hexameric rings, but the mechanism of hexamer assembly is unclear. It is generally believed that the specificity in protein/RNA interaction relies on molecular contact through a surface charge or 3D structure matching via conformational capture or induced fit...
