Webb15 juli 2024 · Abstract: Charge anisotropy or the presence of charge patches at protein surfaces has long been thought to shift the coacervation curves of proteins and has been used to explain the ability of some proteins to coacervate on the "wrong side" of their isoelectric point. Webb3.1. Charge distribution Figure 1 represents the charge distribution on protein surfaces from APBS calculations. At pH 5 (Fig. 1.A and 1.B), both proteins are globally positively charged, with a net charge equal to +7 for α-chymotrypsin and +10 for lysozyme. Fig. 1.C and 1.D show the electrostatic potential at protein surfaces when the pH is ...

WebbFor example, Figure 18 shows a theoretical protein which has a net positive charge below its isoelectric point and can bind to a cation exchanger. Above its isoelectric point the protein has a net negative charge and can bind to an anion exchanger. However, the protein is only stable in the range pH 5–8 and so an anion exchanger has to be used. 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.

WebbThese modifications can alter the surface charge distribution and conformation of proteins, forming charge variants with various isoelectric points (pIs). Charge variants have different structures, stabilities, binding affinities, and chemical properties, which directly determine their biological reactivity and pharmacological effects.
