BI276 Lecture Notes - Lecture 7: Teichoic Acid, Cell Membrane, Type Three Secretion System
Document Summary
2- the phosphotransferase system in e. coli. Lecture 7: october 1 2015: structure (bacteria/archaea, function. Slide 4,5 and 6. Phosphorylate/dephosphorylate until the actual transport protein enzyme. Ii a,b,c phosphorylates the sugar molecule: energy derived from phosphoenolpyruvate. Protein export (large molecule transportation) 3- abc (atp- binding cassette) systems. The cell wall of bacteria: peptidoglycan. Gram- positive cell walls: the cell wall of bacteria: peptidoglycan, the outer membrane, cell walls of archaea. In : or they live in osmotically protected environment such as animal body. Slide 27 and 28. Prokaryotes that lack cell walls. Able to survive without a cell wall because they are either: G- ve cell wall and the outer membrane. Periplasm: is an area between two selective permeable biological membranes (cytoplasmic membrane and outer membrane) Lecture 8: tuesday october 6th 2015: cell surface structures, cell inclusions, gas vesicles, endospores, polysaccharide layers. Other cell surface structure and inclusions.
