Fig. 3From: Piperonal synthase from black pepper (Piper nigrum) synthesizes a phenolic aroma compound, piperonal, as a CoA-independent catalysisCharacterizaion of PnPNS. A The optimal pH conditions for recombinant MBP-PnPNS. B Kinetic plot of recombinant PnPNS (mean ± S.D.; n = 3). The kinetic properties were calculated with the Michaelis–Menten equation using Sigma plot 12.0. C Transcript copy number of PnPNS from various tissues. The copy numbers were obtained from five biological replicates with four technical replicatesBack to article page
