Category:Acidic proteins

The category groups proteins that have a low isoelectric point (pI), and therefore tend to be negatively charged at physiological pH (7.4).

Quantitatively, proteins in this category have a charge q at physiological pH and a number of residues N such that q/sqrt(N) < -0.25. This criterion is met by roughly one-third of the proteins in Arabidopsis thaliana.
