8783018-4	1996	The peptide map obtained by MALDI-MS after digestion in the gel covers 92% of the IFN-gamma sequence and revealed an N-terminal pyroglutamate residue and one oxidized methionine residue.	Pyrrolidonecarboxylic Acid	128-141	interferon gamma	Homo sapiens	82-91	
3109913-4	1987	Structural analysis of this natural IFN-gamma preparation demonstrated a pyroglutamate residue at the amino terminus and a heterogeneous carboxyl terminus.	Pyrrolidonecarboxylic Acid	73-86	interferon gamma	Homo sapiens	36-45
