Supplier:
AMBEED, INC
Description:
(S)-2-((tert-Butoxycarbonyl)amino)-3-(2,4-difluorophenyl)propanoic acid, Purity: 95%, CAS Number: 167993-00-2, Appearance: White to off-white powder or crystals, Storage: Sealed in dry, 2-8 deg C, Size: 1g
Catalog Number:
(B-4295.0005BA)
Supplier:

Description:
These dipeptide building blocks containing Ser- or Thr-derived oxazolidines (pseudoprolines) proved to be versatile tools for overcoming some intrinsic problems in the field of peptide chemistry. The presence of pseudoprolines within a peptide sequence results in the disruption of β-sheet structures considered as a source of intermolecular aggregation during chain elongation, thus increasing solvation and coupling kinetics in peptide assembly. Therefore, use of pseudoprolines offer new possibilities for accessing large peptides by convergent strategies and chemoselective ligation techniques. Moreover, incorporation of a pseudoproline unit facilitates cyclization of peptides.

Description:
This internally quenched fluorogenic peptide substrate contains anthranilic acid as fluorescent donor and m-nitro-tyrosine as acceptor (quencher). The sequence Abz-RVKRGLAY(NO₂)E is based on the sequence of hemagglutinin. The FRET substrate is efficiently cleaved by furin, a subtilisin-like eukaryotic serine endoprotease with Km = 3.8 µM and kcat = 29.3 s⁻¹ (kcat/Km = 7'710'000 M⁻¹s⁻¹). Its kcat/Km value is over 2000-fold higher than that of the commonly used substrate Boc-Arg-Val-Arg-Arg-AMC (I-1645). FRET Substrate for the basic residue-specific yeast aspartyl protease yapsin 1.
