   Legend:   → Mismatch (orange background)
  - → Gap (green background, '-', border residues have a numbering label)
    → Modified Residue (blue background, lower-case, 'x' indicates undefined single-letter code, labelled with number + name)
  x → Chemical Group (purple background, 'x', labelled with number + name, e.g. ACE or NH2)
  extra numbering lines below/above indicate numbering irregularities and modified residue names etc., number ends below/above '|'

Chain A,B,C,D   (PHNX_BACCE | O31156)
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:0000287    magnesium ion binding    Interacting selectively and non-covalently with magnesium (Mg) ions.
    GO:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
    GO:0050194    phosphonoacetaldehyde hydrolase activity    Catalysis of the reaction: H(2)O + phosphonoacetaldehyde = acetaldehyde + H(+) + phosphate.
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.
    GO:0019700    organic phosphonate catabolic process    The chemical reactions and pathways resulting in the breakdown of phosphonates, any organic compound containing one or more C-PO(OH)2 or C-PO(OR)2 (with R=alkyl, aryl) groups. Catabolism of phosphonic acid itself, an inorganic compound without the biochemically relevant C-P bond, is not included.
