Sunflower trypsin inhibitor (SFTI) is a sm … Sunflower trypsin inhibitor (SFTI) is a small, circular peptide produced in sunflower seeds, and is a potent inhibitor of trypsin. It is the smallest known member of the Bowman-Birk family of serine protease inhibitors. One example of Sunflower trypsin inhibitor is Sunflower trypsin inhibitor-1 (SFTI-1). Sunflower trypsin inhibitor-1 is a potent Bowman-Birk inhibitor. Sunflower trypsin inhibitor-1 is the simplest cysteine-rich peptide scaffold because it is a bicyclic 14 amino acid peptide and only has one disulfide bond. The disulfide bond divides the peptide into two loops. One loop is a functional trypsin inhibitory and the second loop is a nonfunctional loop. The nonfunctional loop can be replaced by a bioactive loop. It is extracted from a seed of a sunflower called Helianthus annuus. The synthesis of SFTI is not known however, it can evolutionarily linked to a gene-coded product from classic Bowman-Birk inhibitors. STFI is used in radiopharmaceutical, antimicrobial, and pro-angiogenic peptides.ntimicrobial, and pro-angiogenic peptides.
