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.
cysteine. a sulfur-containing amino acid, one of the nonessential amino acids, produced by enzymatic or acid hydrolysis of proteins; it is readily oxidized to cystine and is sometimes found in urine. (sis-tÄ'in), Do not confuse this word with cystine.ysteine (Cys). [sisâ²tÄn]. an amino acid found in many proteins in the body, including keratin. It is a metabolic precursor of cystine and an important source of sulfur for various body functions.
