Polymorphisms at Amino Acid Residues 141 and 154 Influence Conformational Variation in Ovine PrP

Table 1

Sequence conservation scores for amino acid residues in ovine PrP predicted by the Crescendo algorithm. Ovine PrP amino acid residues with conservation scores >1 are listed. The conservation score quantifies the degree of sequence conservation at an alignment position compared to the average sequence conservation. A score of >1 means the sequence conservation is more conserved than that expected based upon its structure.
