Crystal structure of ConM in complex with trehalose and maltose
OverviewOverview
The crystal structure of Canavalia maritima lectin (ConM) complexed with, trehalose and maltose revealed relevant point mutations in ConA-like, lectins. ConM with the disaccharides and other ConA-like lectins complexed, with carbohydrates demonstrated significant differences in the position of, H-bonds. The main difference in the ConM structure is the replacement of, Pro202 by Ser202, a residue that promotes the approximation of Tyr12 to, the carbohydrate-binding site. The O-6' of the second glucose ring in, maltose interacts with Tyr12, while in trehalose the interaction is, established by the O-2' and Tyr12, explaining the higher affinity of ConM, for disaccharides compared to monosaccharides.
