How do sugar side chains signal vesicle destination in the Golgi apparatus?

[sameeralord]

Ok they say that the sugar side chain signal added to proteins inside the G.A gives the protein direction when it exits through a vesicle. So how does adding a sugar side chain make the vesicle go to the right place?

Thanks!
