cystine arylamidase activity

traitmech:000147 · CLASS · PROPOSED

A physiological enzyme-activity phenotype in which a cell produces active cystine arylamidase enzymes that hydrolyze cystine arylamide substrates.

Trait evidence (3)

  • DOI:10.14202/vetworld.2024.143-149
    Cystine arylamidase 7.5 L-cystyl-2-naphthylamide

    Ludfiani et al. list L-cystyl-2-naphthylamide as the API ZYM cystine arylamidase substrate, grounding the organism-level phenotype as an arylamide-hydrolyzing enzyme activity.

  • DOI:10.3389/fmicb.2022.1034816
    Positive alkaline phosphatase, cystine arylamidase, esterase(C4), esterase lipase(C8), leucine arylamidase, naphthol-AS-B1-phosphohydrolase, valine arylamidase

    Jiang et al. detected cystine arylamidase in the Geminicoccus harenae type strain with the API ZYM enzyme activity panel.

  • DOI:10.2323/jgam.60.59
    In API ZYM, activities are positive for alkaline phosphatase, esterase (C4), leucine arylamidase, valine arylamidase, cystine arylamidase

    An et al. reported cystine arylamidase among positive API ZYM activities for the Flavobacterium panaciterrae DCY69T type strain.

CURATION TODO OPEN cystine-arylamidase-activity-xref-gap · raised by codex · 2026-09-11

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:0004177 covers aminopeptidase activity at molecular-function scope and no live GO class provides an exact residue-specific cystine arylamidase production phenotype at organism-level scope.
