Rasmussen and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogenase, EC: 1.18.6.1 is the enzyme that catalyzes the reduction of dinitrogen to ammonia; this is known as biological nitrogen fixation. Nitrogen fixation is so important to our daily lives, that we utilize approximately 2% of the annual energy produced worldwide to fix nitrogen industrially via the Haber-Bosch process. The industrial process requires a high input of energy in the form of heat (>450o C) and pressure (>200 atm>), while the enzymatic system is performed under ambient conditions. Research invested into understanding the mechanism of this biological catalyst could eventually lead to understanding how nature performs difficult chemical reductions, which could allow researchers to develop catalysts that mimic this enzyme to perform many important reactions, such as nitrogen fixation, much more efficiently than today. Electron transfer in the nitrogenase is only partially understood, and is one of the key elements of understanding the mechanism of nitrogenase. Nitrogenase is composed of two proteins, the Fe protein delivers electrons to the MoFe protein, where N2 binds and is subsequently reduced. The conformational changes that take place upon Fe protein binding were investigated in order to better understand electron transfer within the enzyme. Further, studies were performed which probed the P-cluster, an iron sulfur cluster in the MoFe protein that acts as an intermediate in the electron transfer event, and successfully identified the biologically relevant redox state of the P-cluster, P+1. Other studies were performed which identified several variants of the MoFe protein which were able to accept electrons from a chemical reductant. These variants are the first examples of nitrogenase enzymes able to accept electrons from any source other than Fe protein and shown substrate reduction. These variants pinpoint where nitrogenase is likely to undergo conformational changes to allow electron transfer to the active site of the enzyme. Finally, studies were done on the isolated active site of the protein, the iron molybdenum cofactor to better understand how the active site of nitrogenase works The goal of this thesis is to better understand how electrons travel through nitrogenase, and how they are utilized at the active site, FeMo-cofactor, when they arrive.

Download or read book Catalysts for Nitrogen Fixation written by Barry E. Smith and published by Springer Science & Business Media. This book was released on 2013-03-20 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological nitrogen fixation provides more than 50% of the total annual input of the essential element nitrogen to world agriculture. Thus, it is of immense agronomic importance and critical to food supplies, particularly in developing countries. This book, with chapters authored by internationally renowned experts, provides a comprehensive and detailed account of the fascinating history of the process - including the surprising discoveries of molybdenum-independent nitrogenases and superoxide-dependent nitrogenase; a review of Man's attempts to emulate the biological process - most successfully with the commercially dominant Haber-Bosch process; and the current state of the understanding art with respect to the enzymes - called nitrogenases - responsible for biological nitrogen fixation. The initial chapters use a historical approach to the biological and industrial processes, followed by an overview of assay methodologies. The next set of chapters focuses on the classical enzyme, the molybdenum nitrogenase, and details its biosynthesis, structure, composition, and mechanism of action as well as detailing both how variants of its two component proteins are constructed by recombinant DNA technology and how computational techniques are being applied. The sophisticated chemical modelling of the metal-containing clusters in the enzyme is reviewed next, followed by a description of the two molybdenum-independent nitrogenases - first, the vanadium-containing enzyme and then the iron-only nitrogenase - together with some thoughts as to why they exist! Then follows an up-to-date treatment of the clearly "non-classical" properties of the superoxide-dependent nitrogenase, which more closely resembles molybdenum-containing hydroxylases and related enzymes, like nitrate reductase, that it does the other nitrogenases. Each chapter contains an extensive list of references. This book is the self-contained first volume of a comprehensive seven-volume series. No other available work provides the up-to-date and in-depth coverage of this series and this volume. This book is intended to serve as an indispensable reference work for all scientists working in this area, including agriculture and the closely related metals-in-biology area; to assist students to enter this challenging area of research; and to provide science administrators easy access to vital relevant information.
