To delineate the traffic route through the Golgi apparatus followed by newly synthesized lysosomal enzymes, we subfractionated the Golgi apparatus of rat liver by preparative free-flow electrophoresis into cisternae fractions of increasing content of trans face markers and decreasing contents of markers for the cis face. NADPase was used to mark median cisternae. Beta-Hexosaminidase, the high mannose oligosaccharide processing enzyme, alpha-mannosidase II, the two enzymes involved in the biosynthesis of the phosphomannosyl recognition marker, and the phosphomannosyl receptor itself decreased in specific activity or amount from cis to trans. Additionally, these activities were observed in a fraction consisting predominantly of cisternae, vesicles and tubules derived from trans-most Golgi apparatus elements. These results, along with preliminary pulse-labeling kinetic data for the phosphomannosyl receptor, suggest that lysosomal enzymes enter the Golgi apparatus at the cis face, are phosphorylated, and appear in trans face vesicles by a route whereby the phosphomannosyl receptor bypasses at least some median and/or trans Golgi apparatus cisternae.
