From: The molecular mass and isoelectric point of plant proteomes
Trimodal distribution of isoelectric points (pI) and the molecular mass (kDa) of plant proteins. The pI of plant proteins ranged from 1.99 (epsin) to 13.96 (hypothetical protein), while the molecular mass ranged from 0.54 (unknown) to 2236.8 (type I polyketide synthase) kDa. The X-axis represents the pI and the Y- axis represents the molecular mass of the proteins
