Description: Sweet Arrow Peptide (SAP) has a Pro-rich structure and is derived from the N-terminal domain of γ-zein, a maize storage protein.  (VXLPPP)n is a new family of peptides that can translocate human cell membranes. Compared with other carrier peptides, this new family presents several advantages including its nonviral origin, amphipathic character, solubility in water, and the absence of a cytotoxic effect at high concentrations, both in vitro and in vivo.  It is noteworthy to mention that SAP retains a PPII conformation if 50% of the sequence remains as proline, forming a left-handed helix of 3.0 residues per turn, which affords three distinct ‘faces’ in aqueous solution, Consequently, spatial parameters of the BBB shuttle could be readily studied through simple mutation of valine, arginine, or leucine amino acids to orthogonal residues at specific sites.
