 Title    Metabolie Activity of Hydroxycinnamic Acid Glucose Esters in Cell Suspension Cultures of Chenopodium rubrum  
 Abstract    Cell suspension cultures o f Chenopodium rubrum accumulate high amounts of metabolically active glucose esters of ^?-coumaric and ferulic acid. Pulse-labelling experiments using [14C]phe-nylalanine and application o f the phenylalanine ammonia-lyase (PAL) inhibitor L-a-aminooxy-/3-pnenylpropionic acid (AOPP) revealed that the glucose esters are subject to high turnover. A considerable portion o f the ferulic acid was found as an insoluble component, probably bound to cell wall material. Application of m-fluoro-DL-tyrosine (MFT), an effective inhibitor o f tyrosine biosynthesis via L-arogenate, markedly increased the amount of 1-p-coumaroyl-and 1-feruloyl-glucose accumulated.

 Title    Cell Wall-Bound Phenolics from Norway Spruce (Picea abies) Needles  
 Abstract    Insoluble phenolics have been isolated and identified from Norway spruce (Picea abies [L.] KARST.) needles as cell wall-bound astragalin (kaempferol 3-O-ß-glucoside) and p-coumaric acid as major components, and ferulic acid as a minor one. They probably mainly occur as lignin-carbohydrate complexes.

 Title    Partial Purification and Some Properties of a Hydroxycinnamoyl Glucosyltransferase from Tomato Fruits  
 Abstract    A glucosyltransferase was isolated from im mature "cherry" tom atoes and was partially purified (200-fold) by am m onium sulphate precipitation and successive chrom atography on Sephadex G-100 and DEAE-cellulose columns. The enzyme utilised the free hydroxycinnamic acids and UDP-glucose in the form ation o f their respective glucosides (pH 8.0) and glucose esters (pH 7.0); but did not accept the CoA thiolesters o f HCAs in the presence of glucose-1-phosphate. The constant glucoside/glucose ester ratio observed during purification suggests that both reactions are catalysed by the sam e enzyme. The K m values for /»-coumaric, caffeic, ferulic and sinapic acids were 0.8, 1.5, 1.4 and 2.5 hm, respectively. W ith ferulic acid as substrate, the K m value for U D PG was 10 hm. The enzyme required an -S H group for activity and the reaction was strongly inhibited by EDTA, divalent metal ions and UDP.
