Application


  • Site-Specific Conversion of Cysteine in a Protein to Dehydroalanine Using 2-Nitro-5-thiocyanatobenzoic Acid: This research demonstrates the use of 2-Nitro-5-thiocyanatobenzoic acid in protein engineering to modify cysteine residues, which is critical for developing therapeutic proteins and understanding protein structure-function relationships (Qiao et al., 2021).

  • Scrapie prion protein structural constraints obtained by limited proteolysis and mass spectrometry: Highlights the utility of 2-Nitro-5-thiocyanatobenzoic acid in the study of prion proteins, providing insights into protein misfolding diseases which can lead to novel therapeutic approaches (Sajnani et al., 2008).

  • Localization of a substrate binding domain of the human reduced folate carrier to transmembrane domain 11 by radioaffinity labeling and cysteine-substituted accessibility methods: Utilizes 2-Nitro-5-thiocyanatobenzoic acid in biochemical assays to understand transporter proteins, essential for drug delivery and targeting (Hou et al., 2005).

  • A novel procedure for the preparation of biologically active recombinant peptides using a cyanylation reaction: Describes a method using 2-Nitro-5-thiocyanatobenzoic acid for peptide synthesis, beneficial for the development of peptide-based pharmaceuticals (Koyama et al., 1994).

Biochem/physiol Actions

2-nitro-5-thiocyanatobenzoic acid (NTCB) is commonly used to cyanylate and cleave proteins at cysteine residues.

Escherichia coli dihydroorotase contains six cysteines/subunit, which are potential ligands of structural and catalytic zinc metals at protein sites of the enzyme. Specific thiol reagents modify, in nondenaturing conditions only, two of these cysteines; these two residues are thought to

Phosphorylation of tau protein at Ser-262 has been shown to diminish its ability to bind to taxol-stabilized microtubules. The paired helical filaments (PHFs) found in Alzheimer's disease brain are composed of PHF-tau, which is hyperphosphorylated at multiple sites including Ser-262.

Luteinizing hormone (LH) like all other glycoprotein hormones is composed of two dissimilar subunits, alpha and beta, that are non-covalently associated. The heterodimer is stabilized by a region of the beta-subunit called the "seatbelt" because it wraps around the alpha-subunit

A simple methodology has been developed to characterize the number and location of free cysteine and cystine groups in peptides and proteins, using chemical modification and matrix-assisted laser desorption/ ionization time-of flight mass spectrometry (MALDITOF MS). This new approach employs

Keratin-associated proteins (KAPs) are important constituents of the wool cuticle, comprised of the endo-, exocuticle and a-layers, which contribute significantly to the fibre's molecular and mechanical characteristics. Relatively little is known about the distribution of specific KAPs across these layers
