arabinoside/potato

Incubation of a particulate preparation from potato tissue culture cells with UDP-beta-L-[1-3H] arabinose yielded a glycoprotein fraction containing labelled material with the characteristics of hydroxyproline arabinosides. The sugar-protein linkage was resistant to hot alkaline hydrolysis, and the

1. Potato lectin is a glycoprotein that contains about 47% (by weight) l-arabinose, 3% d-galactose and 11% hydroxyproline. It has a monomeric molecular weight of about 50000 and probably exists as a monomer-dimer system in aqueous solution, with the monomer predominating. It has a very high

1. Methylation analysis of potato (Solanum tuberosum) lectin and thorn-apple (Datura stramonium) lectin confirmed previous conclusions that both glycoproteins contained high proportions of l-arabinofuranosides and lesser amounts of d-galactopyranosides. The arabinofuranosides are present in both

1. The use of a modified sodium chlorite/acetic acid delignification procedure for the solubilization of a hydroxyproline-rich glycoprotein fraction from the depectinated cell walls of Phaseolus coccineus is described. 2. The crude glycoprotein was associated with some pectic material;

The lectin from Datura stramonium (thorn-apple; Solanaceae) has been purified by affinity chromatography and shown to be a glycoprotein containing about 40% (w/w) of carbohydrate. The most abundant amino acids are hydroxyproline, cystine, glycine and serine. Results obtained by gel filtration in
