Chain A,B,C   (FIBER_BPK1F | Q04830)
molecular function
    GO:0016996    endo-alpha-(2,8)-sialidase activity    Catalysis of the endohydrolysis of (2->8)-alpha-sialosyl linkages in oligo- or poly(sialic) acids.
    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:0016798    hydrolase activity, acting on glycosyl bonds    Catalysis of the hydrolysis of any glycosyl bond.
biological process
    GO:0008152    metabolic process    The chemical reactions and pathways, including anabolism and catabolism, by which living organisms transform chemical substances. Metabolic processes typically transform small molecules, but also include macromolecular processes such as DNA repair and replication, and protein synthesis and degradation.
