Molybdenum cofactors, enzymes and pathways
TL;DR: The biosynthetic pathways leading to both types of cofactor have common mechanistic aspects relating to scaffold formation, metal activation and cofactor insertion into apoenzymes, and have served as an evolutionary 'toolbox' to mediate additional cellular functions in eukaryotic metabolism.

Dealing with methionine/homocysteine sulfur: cysteine metabolism to taurine and inorganic sulfur
Martha H. Stipanuk,Iori Ueki +1 more
TL;DR: Synthesis of cysteine as a product of the transsulfuration pathway can be viewed as part of methionine or homocysteine degradation, with Cysteine being the vehicle for sulfur conversion to end products (sulfate, taurine) that can be excreted in the urine.

Molybdenum and tungsten enzymes: a crystallographic and mechanistic overview
TL;DR: An overview of the X-ray crystallography data for representative members of the three enzyme families is given here, focusing on the mechanistic implications drawn from the structural data.

Bioinorganic chemistry of molybdenum and tungsten enzymes: A structural–functional modeling approach
Amit Majumdar,Sabyasachi Sarkar +1 more
TL;DR: The protocols and methodologies adopted to achieve these model systems compared with various other model systems described in this review give testimony to chemist's ability, through chemical manipulations, to achieve the models which may potentially serve as structural–functional mimics of natural enzyme systems.
Journal ArticleDOI
Surviving in the presence of sulphur dioxide: strategies developed by wine yeasts.
TL;DR: In this review, the chemistry of SO2 in wine is explained together with the impact ofSO2 on yeast cells, and the different defence mechanisms are described and discussed, mostly based on current knowledge available for Saccharomyces cerevisiae.

The Metabolic and Molecular Bases of Inherited Disease
TL;DR: In this paper, the authors present a list of disorders of MITOCHONDRIAL FUNCTION, including the following: DISORDERS OF MIOCHONDRIC FERTILITY XIX, XVI, XIX.
Journal ArticleDOI
Natural engineering principles of electron tunnelling in biological oxidation-reduction.
TL;DR: The 14 Å or less spacing of redox centres provides highly robust engineering for electron transfer, and may reflect selection against designs that have proved more vulnerable to mutations during the course of evolution.
Journal ArticleDOI
The Mononuclear Molybdenum Enzymes
TL;DR: It is now well-established that all molybdenum-containing enzymes other than nitrogenase fall into three large and mutually exclusive families, as exemplified by the enzymes xanthine oxidation, sulfite oxidase, and DMSO reductase; these enzymes represent the focus of the present account.
Journal ArticleDOI
Electron Transfer In Proteins
TL;DR: Analyses of electronic-coupling strengths suggest that the efficiency of long-range ET depends on the protein secondary structure: beta sheets appear to mediate coupling more efficiently than alpha-helical structures, and hydrogen bonds play a critical role in both.
Journal ArticleDOI
Overview of the marine roseobacter lineage.
TL;DR: Representatives of the Roseobacter clade stand out as representing one of the most readily cultivated of the major marine lineages, and are serving as the foundation for an improved understanding of marine bacterial ecology and physiology.
