PSA, PsA
|
Molecular structure of
Garden pea:PSA, PsA
|
Pisum sativum
|
| Lecster ID:532 | Edit Entry |
| Source Organism: | Garden pea |
| Species: | Pisum sativum |
| Common Nomenclature: | PSA, PsA |
| Class: | Legume lectins |
| Index Nomenclature: | LECp.Pis.Sat.se.Hmg1 (PSA, PsA) LECp.Pis.Sat.ro.Hmg1 |
| Characterization Notes: | For Pisum isolectin characterization, see: Plant Mol Biol 1994 Jan;24(1):75-81 Pea lectin is a mixture of isolectins that can be separated by ion exchange chromatography. fucose residues were shown to be an importan determinant in the tight binding of glycopeptides to pea lectin. See: J Bio Chem 1981 (256); 6633-6640 For further characterization of monoclonal antibody 6,F-8 reacting with Lathyrus, Lens and Pisum lectins, see: FEBS Lett. 1989 Apr 10;247(1):77-80. |
| Biological Activity: | agglutinates human group A erythrocytes at a titer of 1:4; group B erythrocytes at a titer of 1:4; group B erythrocytes at a titer of 1:2; by crude lectin preparation (16mg/ml). See: Int J Cancer 1970 (6):283 For characterization of mitogenic properties, see: J Biol Chem. 1974 Sep 25;249(18):6004-12 and Proc Nat Acad Sci 1973 (70); 3650-3654 The pea lectin is used in histochemistry for the staining of N-glycans and is extensively used to visualize the acrosomal status of spermatozoa. See: Human Reprod 1994 (9); 1322-1327 The lectin can be used for the purification of feline Tlymphocytes from periferal blood. See: J Immunol Meth 1994 (175); 189-199 |
| Source Tissue: | Seeds, roots |
| Specificity: | PSA: Man/Glc(Man>Glc/GlcNAc)
Lectin 2: Man/Glc (d-mannose, d-glucose) The specificity of PSA is similar to Lens culinaris lectin and ConA. |
