Compositions and methods for solubilizing glycosyltransferases

Abstract

The present disclosure relates to a nucleic acid construct having a chimeric nucleic acid molecule encoding a tripartite glycosyltransferase fusion protein. The chimeric nucleic acid molecule includes a first nucleic acid moiety encoding an amphipathic shield domain protein; a second nucleic acid moiety encoding a glycosyltransferase; and a third nucleic acid moiety encoding a water soluble expression decoy protein. The first nucleic acid moiety is coupled to the second nucleic acid moiety's 3′ end and the third nucleic acid moiety is coupled to the second nucleic acid moiety's 5′ end. The coupling may be direct or indirect. The present disclosure further relates to an expression vector, a host cell, and a tripartite glycosyltransferase fusion protein encoded by the nucleic acid construct. Also disclosed are methods of recombinantly producing a tripartite glycosyltransferase fusion protein in soluble form and methods of cell-free glycan remodeling.
