A prenyltransferase activity (EC 2.5.1.1) has been partially purified from the flavedo of Citrus sinensis with 30–40-fold purification and 35–60 % yield. The enzyme catalyses the condensation of IPP with DMAPP or GPP. The products are neryl and g

Hydrolysis of geranyl pyrophosphate is catalyzed by salts of Mn2+ and involves C-O bond cleavage. The first order rate constants reach limiting values with [Mn2+] > 10−2 M, and the most reactive species is GPP(Mn2+)2 at the optimum pH of 6.5–7. T
