BANANA LECTIN BOUND TO XYL-B1,3 MAN-A-O-METHYL (XM)
Overview
Banana lectin (Banlec) is a dimeric plant lectin from the jacalin-related, lectin family. Banlec belongs to a subgroup of this family that binds to, glucose/mannose, but is unique in recognizing internal alpha1,3 linkages, as well as beta1,3 linkages at the reducing termini. Here we present the, crystal structures of Banlec alone and with laminaribiose (LAM) (Glcbeta1, 3Glc) and Xyl-beta1,3-Man-alpha-O-Methyl. The structure of Banlec has a, beta-prism-I fold, similar to other family members, but differs from them, in its mode of sugar binding. The reducing unit of the sugar is inserted, into the binding site causing the second saccharide unit to be placed in, the opposite orientation compared with the other ligand-bound structures, of family members. More importantly, our structures ... [(full description)]
