Cysteine residues in homologous proteins (those of common ancestry) are very conservative according to PAM 250 scoring matrix . Only Trp is statistically more conservative than Cys. Fig 4. PAM 250 scoring matrix of Dayhoff mutation data matrix. Note that the highest values indicating replacement of a residue into itself is for Trp and Cys. That means the two residues are the most conservative in homologous sequences. The reason is that cysteine - because of disulfide bridges - plays very important role in stabilization of protein structure at higher level.
One key fibrolytic protein, plasmin, circulates in the blood as plasminogen, an inactive protein made of several domains. Five domains are kringle domains that help plasmin bind to lysine residues in fibrin, while the catalytic domain exhibits protease activity that fragments the fibrin network.
