摘要: Abstract We examined 66 aromatics for carboxylation by the γ-resorcylic acid decarboxylase from Rhizobium radiobacter WU-0108 under reverse reaction conditions. The enzyme carboxylated resorcinol, catechol, 5-methylresorcinol and three hydroxystilbenes (resveratrol, gnetol, piceatannol) with high yields. Except structures of these substrates include a 1,3-dihydroxybenzene moiety. Other compounds gave no products. products resveratrol gnetol were 2,6-dihydroxy-4-[(E)-2-(4-hydroxyphenyl)ethenyl]benzoic 2,6-dihydroxy-4-[(E)-2-(2,6-dihydroxyphenyl)ethenyl]benzoic acid, respectively, as determined mass spectrometry nuclear magnetic resonance analyses. Kinetic analyses reactions indicated that are better than resorcinol or catechol.
