AbstractSeveral heme aa3-type cytochrome c oxidases, purified from the cytoplasmic membranes of bacteria, are able to catalyze the same reactions as the structurally far more complex eukaryotic enzyme, i.e., electron transport from cytochrome c to oxygen coupled to proton translocation. However,...
AbstractThe high energy costs of biological nitrogen fixation are partly caused by hydrogen production during the reduction of dinitrogen to ammonia. Some nitrogen-fixing organisms can recycle the evolved hydrogen via a membrane-bound uptake hydrogenase. The energetic aspects of hydrogen...
AbstractData are presented that all known periplasmic redox proteins from the sulfate reducing bacteria included in the genus, Desulfovibrio have aminoterminal (N-terminal) amino-acid sequences commonly found in other Gram-negative bacteria and are indicative of recognition sites for signal...
