Natural toxins. 5(1)
A method is described to sulfate PSP toxins at various positions in the molecule and to prepare 35S labelled compounds using H2(35)SO4 in the presence of dicyclohexylcarbodiimide (DCC). The 11-sulfates of saxitoxin and neosaxitoxin, known as gonyauto

Gigartinine, 5-(3-amidinoureido)-2-aminovaleric acid, and L-citrullinyl-L-arginine were islated from aqueous extracts of Chondrus crispus (Rhodophyceae). Their identifications were confirmed by chemical procedures, and 1H and 13C nuclear magnetic res

Experiments in tank cultures with Chondrus crispus Stackh. have shown that the dipeptide citrullinyl-arginine can accumulate to high concentrations when plants are supplied with nitrate or ammonia at low temperatures. With nitrate only, low light int

The occurrence of three glutamate agonists — glutamic acid, D-homocysteic acid and kainic acid — in a spontaneous mutant of Palmaria palmata is reported. Glutamic acid and D-homocysteic acid, but not kainic acid, were found in the wild-type plant

Cytochrome f was isolated from the brown alga Alaria esculenta and the amino acid sequence was determined. The native haemoprotein has a molecular weight of 9800 and consists of a single polypeptide chain of 86 amino acid residues with a haem group b

The amino acid sequence of Phaseolus aureus L. (mung-bean) cytochrome c has been determined. The molecule consists of a single polypeptide chain of 111 amino acid residues and is homologous with other mitochondrial cytochromes c. Comparison with the

Cytochrome c was isolated and purified from dark-grown seedlings of mung bean, sunflower, sesame, castor oil and buckwheat. The major steps of the method employed were adsorption on Amberlite CG-50, concentration on Sephadex CM-50, molecular sieve ch

'Heavy' mitochondrial preparations of bean, cauliflower, and rat liver have been found to give unimodal distribution for electrophoretic mobility against number of particles. The pH-mean mobility curves were similar in form and consistent with the mi

The amino acid sequence of mung bean and sunflower cytochromes c have been determined on 3 y moles of pure cytochrome by using a combination of high voltage paper electrophoresis and sequence analysis by the Dansyl/Edman method. These data have been

Chromatographic fractionation of extracts of the flagellate M. lutheri yielded 1,4/2,5-cyclohexanetetrol, 2-deoxy-myo-inositol, and myo-inositol in approximately 7%, 2%, and 0.6% of the cellular dry weight. The distribution of cyclitols in algae is s
