These candidates are enriched
in cysteine residues, with PTTG 00248, PTTG 04843, and
PTTG 08334 containing 13 residues each. The 177 residue
protein PTTG 11654 was 6.8% cysteine (12 residues). Cysteine
residues are rare, occurring approximately 84 000 times
in the entire predicted genome of P. triticina
