What are the last 3 steps in processing protein?
4. As proteins are processed, they are moved from one Golgi stack to the next by transfer vesicles. In the Golgi stacks, the unused part of proteins are removed by one set of enzymes and, if a glycoprotein is being produced, the branched sugar groups are added here.
5. The last transfer vesicle fuses with the exit (trans) face of the Golgi.
6. The processed, completed protein is packaged into a vesicle and the vesicle is shed from the exit face of the Golgi.
