1vk0 is a 6 chain structure with sequence from Arabidopsis thaliana. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
RICE2_ARATH 3'-to-5' exoribonuclease (RNase) specifically targeting single-stranded RNAs (PubMed:28463111). Triggers miRNA accumulation in RNA-induced silencing complex (RISC), composed of miRNAs and AGO proteins, by degrading uridylated cleavage fragments (PubMed:28463111). Required during plant growth and development (By similarity).[UniProtKB:Q9SF21][1]
