Upon irradiation with elevated light intensities, the ice plant (Mesembryanthemum crystallinum) accumulates a complex pattern of methylated and glycosylated flavonol conjugates in the upper epidermal layer. Identification of a flavonol methylating activity, partial purification of the enzyme, and
An antiserum to alpha-tocoquinone was prepared by immunization of rabbits. Immunization was obtained by injection of a conjugate consisting of the hapten alpha-tocoquinone attached to methylated ovalbumin into the rabbit. The antiserum recognizes the 3,4-dimethyl-p-benzoquinone group of the molecule
The soluble NAD(P)H:(quinone-acceptor) oxidoreductase [NAD(P)H-QR, EC 1.6.99.2] of Nicotiana tabacum L. leaves and roots has been purified. NAD(P)H-QR contains noncovalently bound flavin mononucleotide. Pairs of subunits of 21.4 kD are linked together by disulfide bridges, but the active enzyme is a
