New tasks attributed to Aurora proteins in cell division

(PhysOrg.com) -- When a cell divides, the genetic information in the chromosomes must be passed on error-free to the daughter cells. Researchers at the Friedrich Miescher Laboratory in Tübingen are studying this process ...

Science, such a sweet mystery

I have been teaching and doing research at the university level for more than 40 years, which means that for more than four decades, I have been participating in a deception - benevolent and well intentioned, to be sure, ...

Body clock regulates metabolism

(PhysOrg.com) -- UC Irvine researchers have discovered that circadian rhythms - our own body clock - regulate energy levels in cells. The findings have far-reaching implications, from providing greater insights into the bond ...

Oxygen key to 'cut and paste' of genes

(PhysOrg.com) -- An oxygen-sensitive enzyme has been found to play a key role in how genes create the many different proteins that make up our bodies.

'Promiscuous' enzymes still prevalent in metabolism

Open an undergraduate biochemistry textbook and you will learn that enzymes are highly efficient and specific in catalyzing chemical reactions in living organisms, and that they evolved to this state from their "sloppy" and ...

New mechanism discovered in meiosis

Inactivated, but still active– how modification of an enzyme governs critical processes in sexual reproduction.

Fundamental discovery casts enzymes in new light

Just as a breeze causes leaves, branches and ultimately the tree to move, enzymes moving at the molecular level perform hundreds of chemical processes that have a ripple effect necessary for life. Protein complexes are often ...
