title: Coniferyl alcohol metabolism in conifers -- I. Glucosidic turnover of cinnamyl aldehydes by UDPG: coniferyl alcohol glucosyltransferase from pine cambium.
abstract: UDPG: coniferyl alcohol glucosyltransferase (CAGT; EC 2.4.1.111) isolated from cambial tissues of Pinus strobus was able to convert cinnamyl aldehydes as well as dihydroconiferyl alcohol into their corresponding 4-O-beta-D-glucosides in vitro. Cinnamyl aldehydes were glucosylated with comparable efficiency to coniferyl alcohol, the physiological substrate for CAGT. Seasonal patterns of CAGT activity for aldehydes were similar to those of coniferyl alcohol. Formation of cinnamyl aldehyde and additional monolignol glucosides indicates that precursor flux and availability for lignification is likely greater than previously recognized.
