Peanut agglutinin : ウィキペディア英語版 | Peanut agglutinin
Peanut agglutinin (PNA) is plant lectin protein derived from the fruits of ''Arachis hypogaea''. Peanut agglutinin may also be referred to as ''Arachis hypogaea'' lectin. Lectins recognise and bind particular sugar sequences in carbohydrates; peanut agglutinin binds the carbohydrate sequence Gal-β(1-3)-GalNAc. The name "peanut agglutinin" originates from its ability to stick together (agglutinate) cells, such as neuramidase-treated erythrocytes, which have glycoproteins or glycolipids on their surface which include the Gal-β(1-3)-GalNAc carbohydrate sequence. ==Structure==
The protein is 273 amino acids in length with the first 23 residues acting and a signal peptide which is subsequently cleaved. It has a Uniprot accession of (P02872 ). There are over 20 structures of this protein in the PDB which reveal and all beta-sheet protein with a tetrameric quaternary structure. It is a member of the Lectin_legB PFAM family.
