Fig. 3From: Identification and characterization of a silent mutation in RNA binding domain of N protein coding gene from SARS-CoV-2Tetrameric structure of the RNA binding domain of N protein from SARS-CoV-2. Each monomer contain one binding site for unique ligands including zinc ion (Zn2+), glycerol (GOL), and 2-(N-morpholino)-ethanesulfonic acid (MES)Back to article page
