The present application in one aspect provide Fc-containing polypeptide conjugates comprising an Fc-containing polypeptide conjugated to a conjugate moiety, wherein the Fc-containing polypeptide comprises an N-glycosylated Fc region comprising an acceptor glutamine residue flanked by an N-glycosylation site and wherein the conjugate moiety is conjugated to the Fc-containing polypeptide via the acceptor glutamine residue. Also provided are methods of making such Fc-containing polypeptide conjugates by using a wildtype or engineered transglutaminases. Further provided are engineered transglutaminases specifically designed for carrying out such reactions.
An engineered transglutaminase comprising an amino acid sequence having at least about 80% identity to SEQ ID NO:16, wherein the engineered transglutaminase comprises one or more mutations selected from the group consisting of:
An engineered transglutaminase comprising an amino acid sequence having at least about 80% identity to SEQ ID NO:17, wherein the engineered transglutaminase comprises one or more mutations selected from the group consisting of:
