Using a sucrose density gradient fractionation of a highly purified Golgi apparatus from rat liver, we determined the sub-Golgi distribution of CMP-NeuAc:GM3 ganglioside alpha 2----8sialyltransferase (GM3-SAT) and CMP-NeuAc:GT1b ganglioside alpha 2----8sialyltransferase (GT1b-SAT), in comparison with that of the other glycosyltransferase activities involved in ganglioside biosynthesis. While GM3-SAT was recovered in several density fractions, GT1b-SAT was mainly found on less dense sub-Golgi… CONTINUE READING
