The amino acid sequence of pancreatic alpha-amylase from the ostrich, Struthio camelus.
The amino-acid sequence of alpha-amylase isolated from the pancreas of the ostrich, Struthio camelus was determined. The alpha-amylase (OPA) consisted of 497 amino acid residues with pyroglutamic acid at the N-terminus and no oligosaccharide. Amino acid identity between OPA and chicken, porcine and human pancreatic alpha-amylases individually, was found to be 88, 82 and 86%, respectively.
