Synthesis of cysteinyl-tRNACys by a prolyl-tRNA synthetase.

abstract：:The HIV-1 nucleocapsid protein (NC) is a nucleic acid chaperone, which remodels nucleic acid structures so that the most thermodynamically stable conformations are formed. This activity is essential for virus replication and has a critical role in mediating highly specific and efficient reverse transcription. NC's fun...
