Fig 6: AACompSim output where the serine protease inhibitor IPIA_TOBAC was
matched against proteins from ALL species in the SWISS-PROT database. Many
other serine proteases of type potato chymotrypsin inhibitor I were found,
including ICI1_LYCPE which has only 49% sequence identity with IPIA_TOBAC.
This illustrates that proteins that belong to a family have well-conserved
amino acid compositions. Note how the proteins POL_SIVCZ and IPIB_TOBAC are
not present in the third list because their pI and MW do not fall within the
specified windows. The AACompSim output was shortened for this figure.
