|
|
Two factors influencing how well a protein fits with a ligand |
Specificity Affinity (tendency and strength) |
|
|
|
Physical factors in Ligand binding |
Temperature pH Concentration of protein Concentration of ligand Competition for binding sites |
5 |
|
|
Law of mass action |
Proteins generally have binding sites for molecules which will result in binding if the ligand is within close enough proximity
The more frequently these close encounters occur, the more binding reactions will occur |

|
Acid |
Contributes H+ to solution |
|
|
|
Buffers |
Minimize change in pH by tying up free H+ ions in the solution. |
