Bacterial Sortase Substrate III, Abz/DNP
| Overview | |
|---|---|
| Description | The Staphylococcus aureus transpeptidase Sortase A (SrtA) anchors virulence and colonization-associated surface proteins to the cell wall. SrtA selectively recognizes a C-terminal LPXTG motif. SrtA readily reacts with its native substrate Abz-LPETG-Dap(DNP)-NH2, cleaving it and catalyzing the formation of an amide bond between the carboxyl group of threonine and the amino group of cell-wall crossbridges. Cleavage of this FRET substrate can be monitored at Ex/Em=320 nm/420 nm. |
| Sequence | Abz-LPETG-K(Dnp)-NH2 |
| Sequence (3 Letter) | Abz-Leu-Pro-Glu-Thr-Gly-Lys(Dnp)-NH2 |
| Molecular Weight | 928 |
| Properties | |
| Purity | > 95% By HPLC |
| Storage | Store at -20 °C, cap vial tightly at all times. |
