UDP-GlcNAc [cyto] or UDP-Glc [cyto] or GDP-Man [cyto] | → | UDP-GlcNAc [Golgi] or UDP-Glc [Golgi] or GDP-Man [Golgi] |
* Antiporter transporting nucleotide sugars UDP-N-acetylglucosamine (UDP-GlcNAc), UDP-glucose (UDP-Glc) and GDP-mannose (GDP-Man) from cytosol into Golgi, in exchange for the corresponding nucleosides monophosphates (UMP for UDP-sugars and GMP for GDP-sugars).
