Abstract

Official abstract text for this publication.

Provided are methods of making carrier polypeptide that include incorporating a first unnatural amino acid into a carrier polypeptide variant, incorporating a second unnatural amino acid into a target polypeptide variant, and reacting the first and second unnatural amino acids to produce the conjugate. Conjugates produced using the provided methods are also provided. In addition, orthogonal translation systems in methylotrophic yeast and methods of using these systems to produce carrier and target polypeptide variants comprising unnatural amino acids are provided.

First claim

Opening claim text (preview).

What is claimed is: 1. A carrier polypeptide-target polypeptide conjugate comprising: a carrier polypeptide domain comprising a first unnatural amino acid residue, wherein the carrier polypeptide domain comprises an antibody or antibody fragment; and, a target polypeptide domain comprising a second unnatural amino acid residue; wherein the carrier polypeptide domain and target polypeptide domain are conjugated together through the first and second unnatural amino acid residues…
