alkaline phosphatase activity

traitmech:000141 · CLASS · PROPOSED

A physiological enzyme-activity phenotype in which a cell produces active alkaline phosphatase enzymes that dephosphorylate phosphate-containing compounds.

  • DOI:10.1128/JB.185.16.4983-4991.2003
    leads to constitutive expression of a protein with alkaline phosphatase activity

    Kriakov et al. identified a Mycobacterium smegmatis phoA gene whose expression yields a protein with alkaline phosphatase activity.

  • DOI:10.1155/2021/8888641
    According to the API ZYM assays, all three isolates were positive for alkaline phosphatase, leucine aryl amidase, acid phosphatase, and naphthol_AS_BI_phosphohydrolase.

    Mekonnen et al. treated alkaline phosphatase as an assayed bacterial exoenzyme phenotype in rapid urease-producing soil isolates.

Not yet attached to a section of this record — a curator sets attaches_to (e.g. causal_graphs#some_edge) so the gap shows beside the mechanism it concerns.

GO:0004035 carries the same alkaline phosphatase activity label but denotes the enzyme molecular function rather than the organism-level phenotype, so it is appropriate as a causal-node grounding rather than an equivalent TraitRecord xref.
