Abz-Ser-Pro-Tyr(NO2)-OH is a peptide that has been shown to be an angiotensin I converting enzyme II (ACE) substrate and an inhibitor of ACE. It also inhibits the release of renin from the juxtaglomerular apparatus, which is needed for the production of angiotensin II. This peptide is used in biochemical research and as a standard for measuring enzymatic activity.
Abz标记肽的说明:
2-Aminobenzoyl, or Anthraniloyl, (Abz) is a fluorophor with an excitation at 320 nm ▉ and emission of 420 nm ▉.
Selective substrate for angiotensin-converting enzyme 2 (ACE2), an ACE homolog which differs in its specificity and physiological role from ACE. The internally quenched fluorescent (FRET) substrate is potentially useful in applications such as high-throughput screening of ACE2 inhibitors (Km = 23 µM, kcat/Km = 3.5 · 10⁴ M⁻¹s⁻¹).
