Protein Structure
Flashcards do conjunto (9)
- 1hydrophobic effect.
- 2Do membrane proteins have more or less secondary structure than hydrophilic proteins? Why?MORE. B/c H-bonding
- 3Protein AllosteryPr binding A alters Pr's affinity for B
- 4Tense "T" State-binds O2 w/ low affinity
-favored at LOW O2 concentration - 5Relaxed "R" State-binds O2 w/ much higher affinity
-binding energy w/ O2 stabilizes R
-becomes predominant as O2 concentration increases - 6Bohr effect in Hb shifts O2 aff in pH range of 6-8. What AA might be contributing to pH dependence?His. pKA ~ 6, so can pick up or lose H+ around phys pH
- 7holoenzyme vs. apoenzyme.
- 8When [s] = Km,When [s] is increased 100x, v will increase 2x
(100x ~ vmax. Km = 1/2 vmax) - 94 factors that affect enzyme activity
