CC -!- FUNCTION: Involved in the biosynthesis of benzyl acetate, a major
CC constituent of the floral scent. Can use benzylalcohol,
CC cinnamylalcohol, 3-cis-hexene-1-ol or heptanol as substrates. Has some
CC activity with 2-phenylethanol and 2-naphtalene-ethanol, but no activity
CC with linalool, 2-hydroxybenzylalcohol, 3-hydroxybenzylalcohol or 4-
CC hydroxybenzylalcohol. {ECO:0000269|PubMed:10588064,
CC ECO:0000269|PubMed:9628024}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=acetyl-CoA + benzyl alcohol = benzyl acetate + CoA;
CC Xref=Rhea:RHEA:36147, ChEBI:CHEBI:17987, ChEBI:CHEBI:52051,
CC ChEBI:CHEBI:57287, ChEBI:CHEBI:57288; EC=2.3.1.224;
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(E)-cinnamyl alcohol + acetyl-CoA = (E)-cinnamyl acetate +
CC CoA; Xref=Rhea:RHEA:36151, ChEBI:CHEBI:33227, ChEBI:CHEBI:57287,
CC ChEBI:CHEBI:57288, ChEBI:CHEBI:156069; EC=2.3.1.224;
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC Kinetic parameters:
CC KM=240 uM for benzyl alcohol {ECO:0000269|PubMed:10588064};
CC KM=24 uM for acetyl-CoA {ECO:0000269|PubMed:10588064};
CC Vmax=556 pmol/sec/mg enzyme {ECO:0000269|PubMed:10588064};
CC -!- TISSUE SPECIFICITY: Expressed in petals, style, sepals and stamens.
CC Very low expression in stigma and not detected in leaves.
CC {ECO:0000269|PubMed:9628024}.
CC -!- DEVELOPMENTAL STAGE: Expression in petals peaks on the day of anthesis.
CC {ECO:0000269|PubMed:10588064, ECO:0000269|PubMed:9628024}.
CC -!- PTM: The N-terminus is blocked.
CC -!- SIMILARITY: Belongs to the plant acyltransferase family. {ECO:0000305}.
CC -!- CAUTION: The cv. non-scented line contains a lower amount of the
CC protein (AC Q9SPU3) and a lower activity, even though it has similar
CC levels of mRNA (PubMed:10588064). {ECO:0000305|PubMed:10588064}.
