Protein lifetime and the stability of cell structures

(Phys.org) —The ability of a cell to move, replicate, and recast itself according to the needs of the organism which it serves, comes at it price. The extreme flexibility of cells takes its origin from the constant turnover ...

Making blood-sucking deadly for mosquitoes

Inhibiting a molecular process cells use to direct proteins to their proper destinations causes more than 90 percent of affected mosquitoes to die within 48 hours of blood feeding, a UA team of biochemists found.

How to code a functional molecular machine

An international team has developed a model that simulates protein evolution. Starting from stiff, unfunctional proteins, the computer model shows how evolving protein components can work together to give rise to dynamic ...

Operation of ancient biological clock uncovered

A team of Dutch and German researchers has discovered the operation of one of the oldest biological clocks in the world, which is crucial for life on earth as we know it. The researchers applied a new combination of cutting-edge ...
