naphthol-AS-BI-phosphohydrolase activity

traitmech:000174 · CLASS · PROPOSED

A physiological enzyme-activity phenotype in which a cell produces active phosphohydrolases that hydrolyze naphthol-AS-BI-phosphate substrates.

Trait evidence (2)

  • DOI:10.14202/vetworld.2024.143-149
    Naphthol-AS-BI-phosphohydrolase 5.4 Naphthol-AS-BI-phosphate

    Ludfiani et al. list Naphthol-AS-BI-phosphate as the API ZYM naphthol-AS-BI-phosphohydrolase substrate, grounding the organism-level phenotype as hydrolysis of the naphthol-AS-BI phosphate chromogenic substrate.

  • DOI:10.1128/JCM.43.8.3713-3717.2005
    Alkaline phosphatase, esterase (C4), esterase lipase (C8), leucine arylamidase, acid phosphatase, and naphthol-AS-BI-phosphohydrolase were clearly positive

    Otsuka et al. detected clear naphthol-AS-BI-phosphohydrolase API ZYM reactions in the five Corynebacterium resistens isolates they characterized.

CURATION TODO OPEN naphthol-as-bi-phosphohydrolase-activity-xref-gap · raised by codex · 2026-09-12

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:0016791 covers broad phosphatase activity at molecular-function scope, and no live GO class provides an exact naphthol-AS-BI-phosphate-specific phosphohydrolase production phenotype at organism-level scope.

Curation history

  1. · MINTED_TRAITMECH_ID · codex

    Minted naphthol-AS-BI-phosphohydrolase activity as a DOI-backed TraitRecord after a repository-wide duplicate review covering ignored and hidden files; METPO has no exact naphthol-AS-BI-phosphohydrolase activity class yet and the placeholder is reserved in proposals/metpo_traitmech_v51.
