Recombiniant gamma interferons having enhanced stability and methods therefor

摘要

The present invention relates to novel, stable recombinant gamma interferons exhibiting in greater or less degree the antiviral and antiproliferative activity in humans and pH 2 labile properties characteristic of native human gamma interferon. The amino acid sequence of such an interferon comprises, from the N-terminus:wherein X is a methionine residue or hydrogen and Y is a glutamine residue, or, where X is hydrogen, Y is either a glutamine or a pyroglutamate residue.
