The interdomain flexible linker of the polypeptide GalNAc transferases dictates their long-range glycosylation preferences
Abstract
GalNAc transferases’ (GalNAc-Ts) catalytic domains are connected to a lectin domain through a flexible linker. Here the authors present a structural analysis of GalNAc-T4 that implicates the linker region as modulator of the orientations of the lectin domain, which in turn imparts substrate specificity.
