Asymmetric Unit(hide GO term definitions)
Chain A,B,C   (RNBR_BACAM | P00648)
molecular function
    GO:0003723    RNA binding    Interacting selectively and non-covalently with an RNA molecule or a portion thereof.
    GO:0004519    endonuclease activity    Catalysis of the hydrolysis of ester linkages within nucleic acids by creating internal breaks.
    GO:0004521    endoribonuclease activity    Catalysis of the hydrolysis of ester linkages within ribonucleic acid by creating internal breaks.
    GO:0016787    hydrolase activity    Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. Hydrolase is the systematic name for any enzyme of EC class 3.
    GO:0004518    nuclease activity    Catalysis of the hydrolysis of ester linkages within nucleic acids.
    GO:0004540    ribonuclease activity    Catalysis of the hydrolysis of phosphodiester bonds in chains of RNA.
biological process
    GO:0090501    RNA phosphodiester bond hydrolysis    The RNA metabolic process in which the phosphodiester bonds between ribonucleotides are cleaved by hydrolysis.
    GO:0090502    RNA phosphodiester bond hydrolysis, endonucleolytic    The chemical reactions and pathways involving the hydrolysis of internal 3',5'-phosphodiester bonds in one or two strands of ribonucleotides.
    GO:0090305    nucleic acid phosphodiester bond hydrolysis    The nucleic acid metabolic process in which the phosphodiester bonds between nucleotides are cleaved by hydrolysis.
cellular component
    GO:0005576    extracellular region    The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.
