Product Description

Biotin-LPETG Sortase A Peptide is built around the LPETG/LPETGG recognition sequence used by Staphylococcus aureus Sortase A (SrtA). Sortase-mediated ligation, often called sortagging, is a widely used enzymatic method for site-specific peptide and protein modification.

Sortase A Recognition of LPXTG

Sortase A recognizes a C-terminal LPXTG motif, where X can vary. The enzyme cleaves the peptide bond between threonine and glycine and forms a transient thioacyl enzyme intermediate. An N-terminal oligoglycine nucleophile can then attack this intermediate to generate a new peptide bond.

Because recognition is encoded by short peptide motifs, sortase chemistry can be used to attach synthetic peptides, fluorophores, polymers, lipids, proteins, surfaces, and other research components under relatively mild aqueous conditions.

LPETG and LPETGG Research Peptides

LPETG is one of the most frequently used experimental sortase recognition motifs. LPETGG derivatives retain the core LPETG sequence while adding an additional glycine that can be useful in synthetic design or handling.

Special Feature of LT8734

Biotin enables high-affinity capture or detection through streptavidin/avidin reagents.

Scientific Background

Biotin-LPETG Sortase A Peptide is a 9-residue synthetic peptide with the sequence Ile-Thr-Ile-Asn-Leu-Pro-Glu-Thr-Gly. Biotin provides an affinity handle for streptavidin-based capture or detection. These sequence-derived properties describe the reagent chemically; no specific receptor, enzyme, pathway, disease association, or biological activity is assigned without product-specific experimental evidence.

Research Applications
  • streptavidin-based capture or detection
  • binding and pull-down assay development
  • LC-MS/HPLC analytical method development
  • sequence-specific assay controls
Experimental Notes

Sequence-derived chemical properties support reagent selection and experimental planning but do not establish biological function. Solubility, aggregation, adsorption, conjugation efficiency, and assay performance should be validated under the intended experimental conditions.
