Studies on phytohemagglutinins. XXVI. A new type of a lentil hemagglutinin isolated from Lens esculenta Moench., subsp. microsperma (Baumg.) Barulina. 1975

D Fialová, and M Tichá, and J Kocourek

In seeds of the lentil Lens esculenta Moench., subsp. microsperma (Baumg.) Barulina, a nonspecific phytohemagglutinin was found, the properties of which differ from those of the previously described lentil hemagglutinins. The phytohemagglutinin is not adsorbed to the Sephadex matrix; its hemagglutinating activity is different towards erythrocytes of different human blood groups of the ABO system. The isolated phytohemagglutinin preparation is homogeneous by disc polyacrylamide and starch gel electrophoreses and by gel chromatography on Bio-Gel P-100. Ultracentrifugation of the phytohemagglutinin yields a single symmetrical peak with S20,W of 3.9 S. From the sedimentation data, a molecular weight of 53 300 was calculated. Phytohemagglutinins of similar properties were shown to be present also in other cultivars of Lens esculenta, subsp. microsperma.

D008358	Mannose	A hexose or fermentable monosaccharide and isomer of glucose from manna, the ash Fraxinus ornus and related plants. (From Grant & Hackh's Chemical Dictionary, 5th ed & Random House Unabridged Dictionary, 2d ed)	D-Mannose,Mannopyranose,Mannopyranoside,D Mannose
D008362	Mannosides	Glycosides formed by the reaction of the hydroxyl group on the anomeric carbon atom of mannose with an alcohol to form an acetal. They include both alpha- and beta-mannosides.	Mannoside
D008757	Methylglucosides		Methylglucopyranosides
D008970	Molecular Weight	The sum of the weight of all the atoms in a molecule.	Molecular Weights,Weight, Molecular,Weights, Molecular
D010944	Plants	Multicellular, eukaryotic life forms of kingdom Plantae. Plants acquired chloroplasts by direct endosymbiosis of CYANOBACTERIA. They are characterized by a mainly photosynthetic mode of nutrition; essentially unlimited growth at localized regions of cell divisions (MERISTEMS); cellulose within cells providing rigidity; the absence of organs of locomotion; absence of nervous and sensory systems; and an alternation of haploid and diploid generations. It is a non-taxonomical term most often referring to LAND PLANTS. In broad sense it includes RHODOPHYTA and GLAUCOPHYTA along with VIRIDIPLANTAE.	Plant
D002241	Carbohydrates	A class of organic compounds composed of carbon, hydrogen, and oxygen in a ratio of Cn(H2O)n. The largest class of organic compounds, including STARCH; GLYCOGEN; CELLULOSE; POLYSACCHARIDES; and simple MONOSACCHARIDES.	Carbohydrate
D002850	Chromatography, Gel	Chromatography on non-ionic gels without regard to the mechanism of solute discrimination.

D004589	Electrophoresis, Disc	Electrophoresis in which discontinuities in both the voltage and pH gradients are introduced by using buffers of different composition and pH in the different parts of the gel column. The term 'disc' was originally used as an abbreviation for 'discontinuous' referring to the buffers employed, and does not have anything to do with the shape of the separated zones.

D004592	Electrophoresis, Starch Gel	Electrophoresis in which a starch gel (a mixture of amylose and amylopectin) is used as the diffusion medium.	Starch Gel Electrophoresis
D005947	Glucose	A primary source of energy for living organisms. It is naturally occurring and is found in fruits and other parts of plants in its free state. It is used therapeutically in fluid and nutrient replacement.
