NADPH:isoflavone oxidoreductase (IFR) is the first soluble enzyme of the pterocarpan-specific part of phytoalexin biosynthesis in chickpea (Cicer arietinum L.). The enzyme was purified to apparent homogeneity by a five-step procedure from chickpea cell cultures treated with yeast extract as elicitor. Analysis by gel filtration and SDS/PAGE showed that the enzyme consists of a single polypeptide with a molecular mass of 36 kDa. Km values for the substrates 2'-hydroxyformononetin, 2… CONTINUE READING
