Effect of different phenolic compounds on pXd-INV activity. HPLC analysis of the reactions in presence of: (A) hydroquinone (HQ); (B) catechol (CAT); (C) epigallocatechin gallate (EGCG); (D) p-nitrophenol (PNP). The ELSD (black line) and UV (red line, 296 nm for A,D; 241 nm for B,C) detector signals are represented. Reaction conditions: 100 g/L of sucrose, 20 g/L of phenolic compound, 100 mM sodium acetate buffer (pH 5.0), 60 °C. Peaks: (Fru-HQ) Fructosyl-hydroquinone; (Fru) Fructose; (Glc) Glucose; (Suc) Sucrose; (NeoK) Neokestose; (1-K) 1-Kestose; (*) Possible transfructosylation product of CAT.
