CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=an S-alkyl-L-cysteine S-oxide = 2-aminoprop-2-enoate + an S-
CC         alkyl sulfenate; Xref=Rhea:RHEA:20141, ChEBI:CHEBI:22326,
CC         ChEBI:CHEBI:76565, ChEBI:CHEBI:142409; EC=4.4.1.4;
CC   -!- COFACTOR:
CC       Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC   -!- SUBUNIT: Homodimer. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Vacuole.
CC   -!- DOMAIN: The 6 Cys residues of the EGF-like domain are arranged in a
CC       disulfide pattern different from the one found in the canonical EGFs.
CC       The function of this domain is unclear. It may be a binding site for
CC       other proteins or the docking site for a putative alliinase receptor
CC       (By similarity). {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the alliinase family. {ECO:0000305}.
