El Complejo IV o citocromo c oxidasa (COX) es la enzima terminal de la cadena respiratoria de la mitocondria y su ensamblado requiere la formación de centros de cobre en sus subunidades. Las proteínas COX17 y COX19 estarían ...

Deletion of reading frame YHR116W of the Saccharomyces cerevisiae nuclear genome elicits a respiratory deficiency. The encoded product, here named Cox23p, is shown to be required for the expression of cytochrome oxidase. ...

Members of the ubiquitous COX11 (cytochrome c oxidase 11) protein family are involved in copper delivery to the COX complex. In this work, we characterize the Arabidopsis thaliana COX11 homolog (encoded by locus At1g02410). ...

Phylogeography of Setacea puiggariana, which is widely distributed in southern and south-eastern Brazil, with few records in South America and Africa, was investigated based on mitochondrial genetic markers: the cox2-3 ...

The present study evaluates the effect of isolated fractions of Harpagophytum procumbens (devil`s claw) on cyclooxygenase (COX-1 and COX-2) activities and NO production using a whole blood assay. The activity of COX-1 was ...

Mitochondrial cytochrome c oxidase (COX) is the primary site of cellular oxygen consumption and is essential for aerobic energy generation in the form of ATP. Human COX is a copper-heme A hetero-multimeric complex formed ...

RESUMEN: El dolor es la principal causa de asistencia a atención médica. Entre los principales mediadores químicos del dolor están las prostaglandinas, sintetizadas por las ciclooxigenasas de las que existen dos isoformas. ...
