It was previously reported [Nagai, K. & Yamaguchi, H. (1993) J. Biochem. 113, 123-125] that intramolecular high-mannose chains are essential for reconstitution of soybean lectin from denatured subunits. To obtain more detailed information on the role of the intramolecular high-mannose chains in the
We investigated the role of the intramolecular high-mannose oligosaccharide chains in the folding and assembly of soybean lectin polypeptides. Soybean lectin, dissociated into subunits and completely denatured in 6 M guanidine hydrochloride, was quantitatively reconstituted to the active tetrameric
The crystal structure of Pterocarpus angolensis seed lectin is presented in complex with a series of high mannose (Man) oligosaccharides ranging from Man-5 to Man-9. Despite that several of the nine Man residues of Man-9 have the potential to bind in the monosaccharide-binding site, all
We report here the isolation and characterization of a peptide-N4-(acetyl-beta-glucosaminyl) asparagine amidase (peptide: N-glycanase) from soybean (Glycine max) seeds. The enzyme was purified to homogeneity with 6.5% yield from defatted soybean meal extract by ion-exchange chromatography, gel
The structures of N-linked sugar chains (N-glycans) of storage glycoproteins in soybean seeds have been identified. Eight pyridylaminated (PA-) N-linked sugar chains were derived and purified from hydrazinolysates of the storage glycoproteins by reverse-phase HPLC and size-fractionation HPLC. The
BACKGROUND
In fruits with therapeutic properties for antidiarrheal and laxative uses, the presence of lectins may be the bioactive properties that interfere with bacterial adhesion, thought to be competition for glycoside signal sites in the attachment.
METHODS
This study identifies lectins in crude
The zona pellucida glycoconjugate content of several marsupial species was investigated using differential lectin histochemistry. Ovaries from fat-tailed dunnarts, a southern brown bandicoot, grey short-tailed opossums, brushtail possums, ringtail possums, koalas and eastern grey kangaroos were
In the present study carbohydrate residues in taste buds (TBs) and adjacent epithelial formations of a teleostean fish, a frog and the rabbit were detected by means of lectin histochemistry. Biotinylated lectins from Pisum sativum (PSA), Arachis hypogaea (PNA), Dolichos biflorus (DBA), Triticum
Lectins from Ricinus communis and Glycine max, as well as wheat germ agglutinin and concanavalin A, caused a dose-dependent release of histamine from mast cells present in the mixed peritoneal cells from the rat. In addition, histamine release in an IgE-mediated and a compound 48/80-mediated
The isolated perfused mouse liver model was used to study the effects of various lectins on hepatic trapping and killing of Candida albicans. After mouse livers were washed with 20 to 30 ml of perfusion buffer, 10(6) C. albicans CFU were infused into the livers. At the time of recovery, 63% +/- 2%
The antibiotics Streptovirudin and 24010 were tested to determine their effects on the formation of lipid-linked saccharide intermediates associated with glycoprotein biosynthesis in mung bean (Vigna radiata) and suspension-cultured soybean cells (Glycine max cv. Mandarin). In vitro both compounds
Cell-surface carbohydrates of Entamoeba invadens trophozoites were analyzed using (a) a panel of highly purified lectins specific for molecules containing N-acetylglucosamine or sialic acid, N-acetylgalactosamine, galactose, mannose-like residues, and fucose; (b) Escherichia coli K-12 with
Distribution of lectin binding in the testis of the musk shrew, Suncus murinus, was investigated by light and transmission electron microscopy. Not only spermatogenic cells but also Sertoli cells bound some lectins. Canavalia ensiformis agglutinin (Con A) and wheat germ agglutinin (WGA, Triticum
A lectin has been identified in black locust (Robinia pseudoacacia) bark that shares approximately 50% sequence identity with plant class V chitinases but is essentially devoid of chitinase activity. Specificity studies indicated that the black locust chitinase-related agglutinin (RobpsCRA)
Fluorescein isothiocyanate-conjugated lectins include: concanavalin A (Con-A), Dolichos biflorus agglutinin (DBA), Griffonia simplicifolia-I (GS-I), Griffonia simplicifolia-II (GS-II), Arachis hypogaea agglutinin (PNA), Maclura pomifera agglutinin (MPA), Ricinus communis agglutinin-I (RCA-I),
