Structure and Mechanism of Otto Warburg’s Respiratory Enzyme, the Cytochrome c Oxidase

by Hartmut Michel
Structure and Mechanism of Otto Warburg’s Respiratory Enzyme, the Cytochrome c Oxidase
for 18-22 and upwards,
Lectures | 18-22 and upwards | 11 years ago | 2075 views
Rating:

The oxygen, you breathe in, is converted to water by cytochrome c oxidase, using electrons provided by cytochrome c and protons from the aqueous milieu of the body.  This fundamental enzyme has been discovered already in 1886, and studied extensivel....

Tickling Worms: Surprises From Basic Research
for 18-22 and upwards,
Lectures | 18-22 and upwards | 11 years ago | 1978 views
Rating:

Research, at least my research, has never been linear.  I have found that my lab and I often double back on problems after years of inactivity or go off in entirely new directions as dictated by the work and people's interests.  This lack of direct....

Proteases and Their Control in Health and Disease

by Robert Huber
Proteases and Their Control in Health and Disease
for 18-22 and upwards,
Lectures | 18-22 and upwards | 11 years ago | 1385 views
Rating:

Proteolytic enzymes catalyse a very simple chemical reaction, the hydrolytic cleavage of a peptide bond.  Nevertheless, they constitute a most diverse and numerous lineage of proteins.  The reason lies in their role as components of many regulatory....

The Ubiquitin System

by Avram Hershko
The Ubiquitin System
for 18-22 and upwards,
Lectures | 18-22 and upwards | 11 years ago | 1442 views
Rating:

The selective degradation of many short-lived proteins in eukaryotic cells is carried out by the ubiquitin-mediated proteolytic system.  In this pathway, proteins are targeted for degradation by covalent ligation to ubiquitin, a highly conserved sma....
