Musa acuminata : Plantain

Molecular structure of

Musa acuminata

Lecster ID:453 Edit Entry
Source Organism:Plantain
Species:Musa acuminata
Common Nomenclature:PlanLec
Index Nomenclature:LECp.Mus.Acu.xx.Xxxx
Characterization Notes:Banana and plantain lectins are also the first documented examples of jacalin-related lectins, which are abundantly present in the pulp of mature fruits but are apparently absent from other tissues. The banana lectin is a powerful murine T-cell mitogen.
The novel observation was made that banana and plantain lectins recognize internal alpha1,3-linked glucosyl residues, which occur in the linear polysaccharides elsinan and nigeran. Concanavalin A and lectins from pea and lentil, also mannose/glucose binding lectins, did not precipitate with any of these linear alpha-glucans. This is, the authors believe, the first report of the recognition of internal alpha1,3-glucosidic bonds by a plant lectin. It is possible that these lectins are present in the pulp of their respective fruit, complexed with starch. See: Eur J Biochem 2001 May;268(9):2609-15
