MICB 201 Chapter Notes - Chapter 4-5: Atp Synthase, Lysozyme, Cell Envelope
Document Summary
Gram +ve: region between cm & pg layers. Gram -ve: between om and cm (includes pg) Gram +ve is more affected by lysozyme; gram-ve less sensitive by lysozyme. In gram -ve: if loose the om by detergent there will not be lysis (s)-layer. Bump is made up of six layers (p6) In labs (spontaneous mutants), do not need s layers. Spontaneous mutants lost the ability to make s layers. S layers are energetically expensive to make (requires a lot of atp) Embedded in structure by proteinous structure (anchored in cm) Two rings in cm rotate; since rod is attached, causes filament to rotate as well. Energy for rotation supplied by transport of h+ through mot protein (similar to atp synthase) Can rotate in both directions: coli change direction in motion: Once they change direction, one flagella comes out then the bundle comes back together again.
