Endocytic and biosynthetic trafficking pathways to the lysosome⁄vacuole converge at the prevacuolar endosomal compartment. During transport through this compartment, integral membrane proteins that are destined for delivery to the lysosome⁄vacuole lumen undergo multivesicular body (MVB) sorting into internal vesicles formed by invagination of the endo-somal limiting membrane.

Prokaryotes, yeasts and plants synthesize thiamin (vitamin B1) via complex pathways. Animal cells capture the vitamin through specific high-affinity transporters essential for internal thiamin homeostasis. Inside the cells, thi-amin is phosphorylated to higher phosphate derivatives. Thiamin diphos-phate (ThDP) is the best-known thiamin compound because of its role as an enzymatic cofactor.
