Disruption of alpha-mannosidase processing induces non-canonical hybrid-type glycosylation.
Golgi alpha-mannosidase II is essential for the efficient formation of complex-type glycosylation. Here, we demonstrate that the disruption of Golgi alpha-mannosidase II activity by swainsonine in human embryonic kidney cells is capable of inducing a novel class of hybrid-type glycosylation containing a partially processed mannose moiety. The discovery of 'Man(6)-based' hybrid-type glycans reveals a broader in vivo specificity of N-acetylglucosaminyltransferase I, further defines the arm-spec...Expand abstract
