Default Selenium and Selenocysteine in Protein Chemistry

Selenium and Selenocysteine in Protein Chemistry


Selenocysteine, the selenium-containing analogue of cysteine, is the twenty-first proteinogenic amino acid. Since its discovery almost fifty years ago, it has been exploited in unnatural systems even more often than in natural systems. Selenocysteine chemistry has attracted the attention of many chemists in the field of chemical biology owing to its high reactivity and resulting potential for various applications such as chemical modification, chemical protein (semi)synthesis, and protein folding, to name a few. In this Minireview, we will focus on the chemistry of selenium and selenocysteine and their utility in protein chemistry.Se how far we've come: Since its presence in proteins was discovered over 40 years ago, the singular properties of selenocysteine (Sec) have been exploited by protein chemists for a host of different applications. This Minireview summarizes the use of selenium and selenocysteine in various protein chemistry applications, including chemical modifications, protein synthesis, and protein folding.

[NMR paper] Structure of Amorphous Selenium by 2D 77Se NMR Spectroscopy: An End to The Dilemma of Chain vs. Ring
Structure of Amorphous Selenium by 2D 77Se NMR Spectroscopy: An End to The Dilemma of Chain vs. Ring Amorphous selenium, owing to its tremendous technological importance and perhaps to its chemical simplicity, has been studied for nearly a century and yet an unequivocal structural description of this material remains lacking in the literature to date. The primary controversy regarding the structure of a-Se relates to the relative fraction of Se atoms residing in infinite (Se) chains vs. in Se8 rings. Here we present the results of a two-dimensional solid-state 77Se nuclear magnetic...

SEAL by NMR: Glyco-Based Selenium-Labeled Affinity Ligands Detected by NMR Spectroscopy. Related Articles SEAL by NMR: Glyco-Based Selenium-Labeled Affinity Ligands Detected by NMR Spectroscopy. Chemistry. 2014 Sep 5; Authors: Hamark C, Landström J, Widmalm G Abstract We report a method for the screening of interactions between proteins and selenium-labeled carbohydrate ligands. SEAL by NMR is demonstrated with selenoglycosides binding to lectins where the selenium nucleus serves as an NMR-active handle and reports on binding...
