This content is a preprint and has not undergone peer review at the time of posting.

Abstract

This manuscript describes the development and characterization of a second-generation "helping hand" solubilizing tag. This semipermanent tag aids solubility of peptides during purification and handling steps and is compatible with common native chemical ligation conditions. The utility of this tag is demonstrated by the synthesis of the Shiga toxin B subunit.
