Mitochondria of spermatozoa are different from the corresponding organelles of somatic
cells, in both their morphology and biochemistry. The biochemical differences are essentially …

Cytochrome c oxidase (CcO) is the terminal oxidase of the mitochondrial electron transport
chain. This bigenomic enzyme in mammals contains 13 subunits of which the 3 catalytic …

The chapter provides a review of the state of art of the oxidative phosphorylation system in
mammalian mitochondria. The sections of the paper deal with:(i) the respiratory chain as a …

Cytochrome c oxidase (COX) deficiency is characterized by a high degree of genetic and
phenotypic heterogeneity, partly reflecting the extreme structural complexity, multiple post …

The mitochondrion is arguably the most complex organelle in the budding yeast cell
cytoplasm. It is essential for viability as well as respiratory growth. Its innermost aqueous …

Eukaryotic cytochrome c oxidase (COX) is the terminal enzyme of the mitochondrial
respiratory chain. COX is a multimeric enzyme formed by subunits of dual genetic origin …

Organisms from all kingdoms of life use iron-proteins in a multitude of functional processes.
We applied a bioinformatics approach to investigate the human portfolio of iron-proteins. We …

There has been increasing evidence pointing to the mitochondrial respiratory chain (MRC)
as a novel and important target for the actions of 17β-estradiol (E2) and estrogen receptors …

The terminal enzyme of the mitochondrial respiratory chain, cytochrome oxidase, transfers
electrons to molecular oxygen, generating water. Within the inner mitochondrial membrane …

We report that Rcf1 (formerly Aim31), a member of the conserved hypoxia-induced gene 1
(Hig1) protein family, represents a novel component of the yeast cytochrome bc 1 …
