Uptake protein acts as zinc's doorway to the cell

(PhysOrg.com) -- A study to be published as the "Paper of the Week" in the Journal of Biological Chemistry this December details how zinc, an element fundamental to cell growth, enters the cell via zinc-specific uptake proteins. ...

Researchers make a case for free fatty acids

The current global epidemic of obesity-linked diabetes and its associated consequences -cardiovascular, neurological and renal diseases - is a growing public health problem for which therapeutic options are limited.

How bacteria integrate autotransporters into their outer membrane

The bacterial outer envelope is densely packed with proteins that form small pores and facilitate the passage of nutrients, toxins and signaling molecules. Professors Timm Maier and Sebastian Hiller from the Biozentrum of ...

Big, bad bacterium is an 'iron pirate'

(PhysOrg.com) -- Life inside the human body sometimes looks like life on the high seas in the 1600s, when pirates hijacked foreign vessels in search of precious metals.

Plants feel the heat

It's not just humans and animals that suffer when the mercury rises, plants feel the heat too. Heat stress is a major issue in agriculture and can significantly reduce crop yield. Even small increases in temperature can affect ...

Simulation shows how transporter proteins do their work in cells

Inside every plant or animal, proteins called transporters act as cellular doorkeepers, letting nutrients and other molecules in or out as need be. Although transporter proteins are critical for normal cell function – and ...

The clouds of spaghetti that keep DNA data safe

Cells can avoid "data breaches" when letting signaling proteins into their nuclei thanks to a quirky biophysical mechanism involving a blur of spaghetti-like proteins, researchers from the Rockefeller University and the Albert ...
