Comp Biochem Physiol B Biochem Mol Biol. 2000 Dec;127(4):481-90. doi: 10.1016/s0305-0491(00)00282-0.

Abstract

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.
