Biogenesis of respiratory cytochromes in bacteria.
Biogenesis of respiratory cytochromes is defined as consisting of the posttranslational processes that are necessary to assemble apoprotein, heme, and sometimes additional cofactors into mature enzyme complexes with electron transfer functions. Different biochemical reactions take place during maturation: (i) targeting of the apoprotein to or through the cytoplasmic membrane to its subcellular ...
متن کاملBiogenesis of mitochondrial c-type cytochromes.
Cytochromes c and c1 are essential components of the mitochondrial respiratory chain. In both cytochromes the heme group is covalently linked to the polypeptide chain via thioether bridges. The location of the two cytochromes is in the intermembrane space; cytochrome c is loosely attached to the surface of the inner mitochondrial membrane, whereas cytochrome c1 is firmly anchored to the inner m...
متن کاملRedox processes controlling the biogenesis of c-type cytochromes.
In mitochondria, two mono heme c-type cytochromes are essential electron shuttles of the respiratory chain. They are characterized by the covalent attachment of their heme C to a CXXCH motif in the apoproteins. This post-translational modification occurs in the intermembrane space compartment. Dedicated assembly pathways have evolved to achieve this chemical reaction that requires a strict redu...
متن کاملRespiratory systems and cytochromes in Campylobacter fetus subsp. intestinalis.
Cell suspensions of Campylobacter fetus subsp. intestinalis grown microaerophilically in complex media consumed oxygen in the presence of formate, succinate, and DL-lactate, and membranes had the corresponding dehydrogenase activities. The cells and membranes also had ascorbate-N,N,N',N'-tetramethyl-p-phenylenediamine oxidase activity which was cyanide sensitive. The fumarate reductase activity...
متن کاملBiogenesis of outer membranes in Gram-negative bacteria.
The outer membrane, an essential organelle of Gram-negative bacteria, is composed of four major components: lipopolysaccharide, phospholipids, beta-barrel proteins, and lipoproteins. The mechanisms underlying the transport of these components to outer membranes are currently under extensive examination. Among them, the sorting of lipoproteins to the outer membrane of Escherichia coli has been c...
