Acyltransferase involved in the biosynthesis of the floral volatile isoeugenol, and which promotes the formation of phenylacetaldehyde, phenylethyl alcohol, phenyl-ethyl acetate, phenylethyl benzoate and benzyl acetate (PubMed:17241449). Catalyzes the acetylation of coniferyl alcohol to produce coniferyl acetate (PubMed:17241449). Also active toward 1-octanol, cinnamyl alcohol, geraniol and sinapyl alcohol (PubMed:17241449). (E)-coniferol + acetyl-CoA = (E)-coniferyl acetate + CoA (E)-cinnamyl alcohol + acetyl-CoA = (E)-cinnamyl acetate + CoA (2E)-geraniol + acetyl-CoA = (2E)-geranyl acetate + CoA acetyl-CoA + octan-1-ol = CoA + octyl acetate (E)-sinapyl alcohol + acetyl-CoA = (E)-sinapoyl actetate + CoA kcat is 2.05 sec(-1) with coniferyl alcohol as substrate (in the presence of acetyl CoA and at pH 6) (PubMed:17241449). kcat is 2.32 sec(-1) with acetyl CoA as substrate (in the presence of coniferyl alcohol and at pH 6) (PubMed:17241449). kcat is 0.81 sec(-1) with coniferyl alcohol as substrate (in the presence of acetyl CoA and at pH 7.5) (PubMed:17241449). kcat is 1.51 sec(-1) with acetyl CoA as substrate (in the presence of coniferyl alcohol and at pH 7.5) (PubMed:17241449). kcat is 0.82 sec(-1) with benzyl alcohol as substrate (in the presence of acetyl CoA and at pH 7.5) (PubMed:17241449). kcat is 1.13 sec(-1) with acetyl CoA as substrate (in the presence of benzyl alcohol and at pH 7.5) (PubMed:17241449). kcat is 0.91 sec(-1) with 2-phenyl ethanol as substrate (in the presence of acetyl CoA and at pH 7.5) (PubMed:17241449). kcat is 0.93 sec(-1) with acetyl CoA as substrate (in the presence of 2-phenyl ethanol and at pH 7.5) (PubMed:17241449). Optimum pH is 6. Larger substrate spectrum at pH 7.5, with a lower activity, thought. Aromatic compound metabolism; phenylpropanoid biosynthesis. Monomer. Confined to flowers, mostly in petals limbs. Expressed at low levels early stages of floral development (e.g. small bud, medium bud and tube expansion), but accumulates at higher levels at later stages of flower development (e.g. anthesis and 2 days post-anthesis) (PubMed:17241449, PubMed:20543029). Following fertilization by pollen (pollination), a rapid ethylene biosynthesis in the stigma, style and ovary, and later in the corolla, lead to a reduced expression and a subsequent decrease of volatile emission (PubMed:17241449). Up-regulated by EOBII (PubMed:20543029). Circadian-regulation with peak levels occurring at the end of the light period and during the night in flowers (PubMed:17241449, PubMed:26124104). Repressed by ethylene, especially following pollination (PubMed:17241449). Suppression of isoeugenol biosynthesis and reduction of several floral volatiles including phenylacetaldehyde, phenylethyl alcohol, phenyl-ethyl acetate, phenylethyl benzoate and benzyl acetate, but increased accumulation of homovanillic acid and coniferyl aldehyde. Belongs to the plant acyltransferase family.
