molecular function
    GO:0004035    alkaline phosphatase activity    Catalysis of the reaction: an orthophosphoric monoester + H2O = an alcohol + phosphate, with an alkaline pH optimum.
    GO:0003824    catalytic activity    Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific binding sites for substrates, and are usually composed wholly or largely of protein, but RNA that has catalytic activity (ribozyme) is often also regarded as enzymatic.
    GO:0033748    hydrogenase (acceptor) activity    Catalysis of the reaction: H2 + A = AH2.
    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:0030613    oxidoreductase activity, acting on phosphorus or arsenic in donors    Catalysis of an oxidation-reduction (redox) reaction in which a phosphorus- or arsenic-containing group acts as a hydrogen or electron donor and reduces a hydrogen or electron acceptor.
    GO:0016791    phosphatase activity    Catalysis of the hydrolysis of phosphoric monoesters, releasing inorganic phosphate.
    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:0008270    zinc ion binding    Interacting selectively and non-covalently with zinc (Zn) ions.
biological process
    GO:0016311    dephosphorylation    The process of removing one or more phosphoric (ester or anhydride) residues from a molecule.
    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:0055114    oxidation-reduction process    A metabolic process that results in the removal or addition of one or more electrons to or from a substance, with or without the concomitant removal or addition of a proton or protons.
cellular component
    GO:0030288    outer membrane-bounded periplasmic space    The region between the inner (cytoplasmic or plasma) membrane and outer membrane of organisms with two membranes such as Gram negative bacteria. These periplasmic spaces are relatively thick and contain a thin peptidoglycan layer (PGL), also referred to as a thin cell wall.
    GO:0042597    periplasmic space    The region between the inner (cytoplasmic) and outer membrane (Gram-negative Bacteria) or cytoplasmic membrane and cell wall (Fungi and Gram-positive Bacteria).
