Term
| Group transloctation (Phosphotransferase System) |
|
Definition
Used for sugars
sugars are brought into the cell and phosphorylate it at the same time
phosphate donor is PEP
involves at least 4 proteins that act as phosphate carriers of high energy phosphate group from PEP to incoming sugar
saves metabolic eenergy
found in mostly obligate and facultative anaerobes |
