The isoelectric point is the pH at which a compound in this case a protein has no net charge.
32.
Several pectinesterase isoforms differing in molecular weight, isoelectric point and biochemical activity have been identified in dicotyledonous plants.
33.
The molecular weight is 14178 Da, and the isoelectric point is between 4.2 and 4.5.
34.
The molecular weight of the mature protein is 92.5 kdal with an isoelectric point of 5.05.
35.
Recently, a database of isoelectric points for all proteins predicted using most of the available methods had been also developed.
36.
Protein adsorption is most rapid at the isoelectric point because electrostatic repulsion is reduced for proteins with a neutral net charge.
37.
This protein has a pre-modification isoelectric point of 5.57 and alpha helices span most of its length.
38.
The enzyme is predicted to have an isoelectric point of 5.92 and a molecular mass of 23, 576 Da.
39.
In proteins, the isoelectric point ( pI ) is defined as the pH at which a protein has no net charge.
40.
Most of the purified plant pectinesterases have neutral or alkaline isoelectric points and are bound to the cell wall via electrostatic interactions.
