Webb15 okt. 2024 · The charge distribution is usually not uniform and a protein is capable of having both positively and negatively charged patches on its surface. When working with a new protein, I always screen a range of cation and anion exchange resins, both weak and strong, to optimize this purification step. Webb12 feb. 2013 · Our calculations show that the FG-Nups present a highly inhomogeneous charge distribution: Negative charges are concentrated on pore walls, and positive charges are located at the center of the pore. This result suggests that FG-Nup sequences are optimized to present a positive electrostatic environment along the pore axis to facilitate …

Webb23 aug. 2024 · The properties of a protein will be determined partly by whether the side chain functional groups, the N terminal, and the C terminal are charged or not. The HH equation tells us that this will depend on the pH and the pKa of the functional group. If the pH is 2 units below the pKa, the HH equation becomes, -2 = log A/HA, or .01 = A/HA.
