Part of the Lysyl Residues in Wheatα-Amylase is Methylated asN-ε-Trimethyl Lysine

摘要

Amino acid analyses of wheatα-amylase purified from germinating seeds by affinity chromatography showed a high content of a modified lysyl residue. The modified residue was identified asN-ε-trimethyl lysine. The presence of trimethyl lysine inα-amylase is discussed in terms of isozym
