Category:Basic proteins

The category groups proteins that have a high isoelectric point (pI), and therefore tend to be positively 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



\frac{q}{\sqrt{N}} > 0.25 $$

This criterion is met by roughly one-third of the proteins in Arabidopsis thaliana.
