Anwendung

This product is suitable for in vitro ligation of proteins and peptides to other. Sortase A has been shown to create circularized proteins [1], as well as couple polypeptides to a wide range of substituents including polymers [2], lipids [3], fluorophores [4], sugars [5], microspheres [3], peptide nucleic acids [6], among others.

Biochem./physiol. Wirkung

Staphylococcal Sortase A is a bacterial transpeptidase that covalently links proteins to the bacterial cell wall by cleaving between threonine and glycine at an LPXTG recognition motif and catalyzes the formation of an amide bond between the carboxyl-group of threonine and the amino-group of the cell-wall peptidoglycan [7]. This chemistry can be exploited to site-specifically link proteins/peptides with the C-terminal LPETGX motif to other proteins or molecules possessing a glycine or aminomethylene motif [8].

Physikalische Form

A general chemoenzymatic method for the site-specific attachment of lipids to protein substrates is described. Sortase A is used to append short lipid-modified oligoglycine peptides to the C terminus of protein substrates bearing a five amino acid sortase A recognition

Sortase (SrtA), a transpeptidase from Staphylococcus aureus, catalyzes a cell-wall sorting reaction at an LPXTG motif by cleaving between threonine and glycine and subsequently joining the carboxyl group of threonine to an amino group of pentaglycine on the cell wall

Recombinant protein therapeutics often suffer from short circulating half-life and poor stability, necessitating multiple injections and resulting in limited shelf-life. Conjugation to polyethylene glycol chains (PEG) extends the circulatory half-life of many proteins, but the methods for attachment often lack

Sortase A is a transpeptidase that cleaves at a pentapeptide-motif and subsequently transfers the acyl component to a nucleophile containing N-terminal oligoglycines. We investigate the reaction conditions of the sortase-mediated ligation and demonstrate a useful application by the synthesis of

Genetically encoded reporter constructs that yield fluorescently labeled fusion proteins are a powerful tool for observing cell biological phenomena, but they have limitations. Sortagging (sortase-mediated transpeptidation) is a versatile chemoenzymatic system for site-specific labeling of proteins with small (<2 kDa)
