Deletion of the N-terminal dirigent domain in maize beta-glucosidase aggregating factor and its homolog sorghum lectin dramatically alters the sugar-specificities of their lectin domains.

Abstract excerpt

Maize beta-glucosidase aggregating factor (BGAF) and its homolog Sorghum Lectin (SL) are modular proteins consisting of an N-terminal dirigent domain and a C-terminal jacalin-related lectin (JRL) domain. BGAF is a polyspecific lectin with a monosaccharide preference for galactose, whereas SL displays preference for GalNAc. Here, we report that deletion of the N-terminal dirigent domain in the above lectins...
