WebJul 15, 1997 · Nitrogenase catalyzes the reduction of N2, protons, and a number of alternative substrates that contain C-C, C-N, N-N, and N-O double and triple bonds. Recently it has been shown that nitrogenase also reduces the C==S bond of COS and the C==O bond of CO2. The current work demonstrates that the COS a … WebDisulfide bonds are covalent interactions formed between the sulfur atoms of two cysteine residues. As structural bonds in proteins, disulfide bonds stabilize monomeric and multisubunit proteins [1] constituting the only natural covalent link between polypeptide strands. Furthermore, disulfide bonds are involved in enzyme catalysis [2], regulate …

WebTCEP reduces disulfide bonds as effectively as dithiothreitol (DTT), but unlike DTT and other thiol-containing reducing agents, TCEP does not have to be removed before certain … WebPolythiourethanes (PTUs) crosslinked with dynamic disulfide bonds are synthesized via a nonisocyanate approach. First, a difunctional five-membered cyclic trithiocarbonate (1) is … Thiocyanate shares its negative charge approximately equally between sulfur and nitrogen. As a consequence, thiocyanate can act as a nucleophile at either sulfur or nitrogen — it is an ambidentate ligand. [SCN] can also bridge two (M−SCN−M) or even three metals (>SCN− or −SCN<). Experimental evidence leads to … See more Thiocyanate (also known as rhodanide) is the anion [SCN] , a salt or an ester of thiocyanic acid. It is the conjugate base of thiocyanic acid. Common derivatives include the colourless salts potassium thiocyanate See more Thiocyanate is known to be an important part in the biosynthesis of hypothiocyanite by a lactoperoxidase. Thus the complete absence of thiocyanate or reduced thiocyanate in the human body, (e.g., cystic fibrosis) is damaging to the human host defense system.
