Biosynthesis, primary structure and molecular cloning of snowdrop (Galanthus nivalis L.) lectin.
Poly(A)-rich RNA isolated from ripening ovaries of snowdrop (Galanthus nivalis L.) yielded a single 17-kDa lectin polypeptide upon translation in a wheat-germ cell-free system. This lectin was purified by affinity chromatography. Translation of the same RNA in Xenopus leavis oocytes revealed a lectin polypeptide which was about 2 kDa smaller than the in vitro synthesized precursor, suggesting t...
متن کاملBiosynthesis of the Snowdrop (Galanthus nivalis) Lectin in Ripening Ovaries.
The biosynthesis and processing of the Galanthus nivalis agglutinin were studied in vivo in ripening snowdrop ovaries. Using labeling and pulse chase labeling experiments it could be demonstrated that the snowdrop lectin is synthesized as a precursor of relative molecular weight (M(r)) 15,000 which is posttranslationally converted into the authentic lectin polypeptide of M(r) 13,000 with a half...
متن کاملLocalization and topogenesis studies of cytoplasmic and vacuolar homologs of the Galanthus nivalis agglutinin.
The Galanthus nivalis agglutinin (GNA) is synthesized as a preproprotein. To corroborate the role of the different targeting peptides in the topogenesis of GNA and related proteins, different constructs were made whereby both the complete original GNA gene and different truncated sequences were coupled to the enhanced green fluorescent protein (EGFP). In addition, a GNA ortholog from rice that ...
متن کاملGC-MS investigation and acetylcholinesterase inhibitory activity of Galanthus rizehensis.
GC-MS (gas chromatography-mass spectrometry) analyses of alkaloids in the aerial parts and bulbs of Galanthus rizehensis Stern (Amaryllidaceae), collected during two different vegetation periods, was performed. Twenty three alkaloids were identified in four different alkaloid extracts. Acetylcholinesterase (AChE) inhibitory activities of the alkaloid extracts were tested. Both the highest alkal...
متن کاملEffect of diets containing genetically modified potatoes expressing Galanthus nivalis lectin on rat small intestine.
Diets containing genetically modified (GM) potatoes expressing the lectin Galanthus nivalis agglutinin (GNA) had variable effects on different parts of the rat gastrointestinal tract. Some effects, such as the proliferation of the gastric mucosa, were mainly due to the expression of the GNA transgene. However, other parts of the construct or the genetic transformation (or both) could also have ...
