aUsing a substrate to enzyme (S/E) ratio of 67,000 mol mol–1. Reaction conditions: 35 °C, 25% (v/v) DMSO, 100 mM initial concentration of 2; 200 or 397 mM of 2-phenylethanol for McGlc or PcGlc-based reactions, respectively. The quantification of quercetin and compound 6 enabled the determination of the total (i.e., hydrolysis and transglycosylation) and the transglycosylation-specific conversion, respectively
