Glucosyltransferase activities determined in Arabidopsis plan extracts. (a) Structures of the eleven glucose xenobiotic acceptors identified as substrates and (b) activities determined in root and foliar tissue. Potential groups serving as sites for glucosylation are shown in bold. OGT substrates; 2,4,5‐trichlorophenol [1], 4‐nitrophenol [2], 2‐chloro‐4‐trifluoromethylphenol [3], 1‐naphthol [4], triclosan [5]. SGT substrates; 4‐chlorothiophenol [6], 2‐nitro(4‐trifluoromethyl)‐benzenethiol [7], 2‐naphthalenethiol [8]. NGT substrates; 3,4‐dichloroaniline [9], metribuzin, [10], picloram [11].
