Asymmetric Unit(hide GO term definitions)
Chain A,L   (Q7BQ99_SHIDY | Q7BQ99)
molecular function
    GO:0005515    protein binding    Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
    GO:0030598    rRNA N-glycosylase activity    Catalysis of the hydrolysis of the N-glycosylic bond at A-4324 in 28S rRNA from rat ribosomes or corresponding sites in 28S RNA from other species.
biological process
    GO:0017148    negative regulation of translation    Any process that stops, prevents, or reduces the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of proteins by the translation of mRNA or circRNA.

Chain A,L   (STXA_SHIDY | Q9FBI2)
molecular function
    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:0030598    rRNA N-glycosylase activity    Catalysis of the hydrolysis of the N-glycosylic bond at A-4324 in 28S rRNA from rat ribosomes or corresponding sites in 28S RNA from other species.
biological process
    GO:0017148    negative regulation of translation    Any process that stops, prevents, or reduces the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of proteins by the translation of mRNA or circRNA.

Chain B,C,D,E,F,G,H,I,J,K   (STXB_SHIDY | Q7BQ98)
molecular function
    GO:0005515    protein binding    Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
biological process
    GO:0019836    hemolysis by symbiont of host erythrocytes    The cytolytic destruction of red blood cells, with the release of intracellular hemoglobin, in the host organism by a symbiont. The host is defined as the larger of the organisms involved in a symbiotic interaction.
    GO:0009405    pathogenesis    The set of specific processes that generate the ability of an organism to induce an abnormal, generally detrimental state in another organism.
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.
