  1. PROTEIN PHYSICS LECTURE 12

  2. Membrane Globular Fibrous H-bonds & hydrophobics ____

  3. membrane

  4. Bacteriorodopsin with retinal Transport of protons H+

  5. Porin Transport of polar molecules

  6. Pore in membrane. Free energy of charge in the non-polar pore: ~ q2 / [(MEMBRWATER)1/2rPORE] ~ ~ 20 kcal/mol / rPORE(Å)

  7. G-protein Slow decay of GTP = timer of action

  8. Photo- synthetic center

  9. Pigments in photo- synthetic center: Electron transfer chlorophyll   Light 

  10. Tunneling P(X) ~ 10-X(Å) T-independent Frequency of vibrations (attacks): f ~ 1015/sec Successful attacks: fSUCCS.(x)~ P(x)•f, e.g.: fSUCCS.(5Å)~ 10-5+15 ~ ~ 1010/sec Atom  1Å Attenuation of electron density:
