Protein property that is absed only on primary structure

You've come amazingly close to identifying such a property. It is an
average "pKa" based on the pKa's of its constituent amino acid side
chains. It is called the pI or isoelectric point and can be calculated
from the pK's. Understand, however, that the calculated value reflects
only the denatured pI, not necessarily the native pI (the pI of the
native structure). Check out Swiss-Prot for the software to perform this
calculation. Good luck,
