Ni,Fe-haltige Kohlenmonoxid-Dehydrogenasen (CODHs) katalysieren die reversible Reduktion von CO2 zu CO. Mehrere anaerobe Mikroorganismen enthalten mehrere CODHs in ihrem Genom, denen einigen, obwohl sie als annotiert sind, ein Cystein des kanonischen Bindungsmotivs für den Ni,Fe-Cluster im aktiven Zentrum fehlt. Hier berichten wir über Struktur und Reaktivität eines solchen abweichenden Enzyms,...
Homocystein (Hcy),one of the thio-amino acid is known as a risk factor in some cardiovascular diseases with releasing O2 radical . It has also been reported that; there is oxidative stress effects of Hcy in cholestasis. The aim of this study is to determine plasma Hcy alteration and nitric oxide (NO) in liver and its effects on pathologic disfuncti...
Abstract Zur Überwindung der Antibiotika‐Resistenzkrise werden dringend neuartige bakterielle Angriffsziele benötigt. In diesem Artikel untersuchen wir systematisch Pyridoxalphosphat‐abhängige Enzyme ( PLP ‐DEs) in Bakterien, um uns auf Ziele zu konzentrieren, die an entscheidenden Stoffwechselprozessen beteiligt sind. Zu Zweck haben acht Pyridoxal PL )‐Sonden mit Modifikationen verschiedenen P...
Background: Osteoporosis is a multifactorial disease. Mutation in cystein-rich domain2 (CRD2) and domain3 (CRD3) of osteoprotegrin protein can prevent its interaction with receptor activator nuclear factor kappa beta (RANKL) ligand lead to osteoporosis. Objectives: This study aimed investigate the possible alteration exon2 gene encoding CRD2 CRD3 domains osteoporotic women Chahar Mahal va Bakht...
The condensation product of benzil and amino acid cystein has been isolated and used to form mononuclear complex with Copper(II) (Cu(II)L). The ligand (L) has been characterised by – UV/visible, FT-IR, H and C NMR, ESI Mass spectroscopy etc. The Cu(II)L complex has been characterised by various spectroscopic techniques UV/visible, FT-IR, ESI Mass, EPR and Thermo Gravimetric Analysis. The struct...
The functional groups of the amino acids are the tools of catalysis in those enzymes which operate without coenzymes and cofactors [ 1,2]. Among the functional groups of proteins the imidazole, thiol and carboxyl groups are the most interesting ones with respect to their possible role in enzyme catalysis. While the mechanism of action of these groups in monofunctional catalysis has been thoroug...
