How microbes take out the trash

(PhysOrg.com) -- The molecular machinery bacteria use to rid themselves of toxic substances including antimicrobial drugs has been studied in detail by a UA-led team of researchers. A better understanding of these mechanisms ...

Blame the 'chaperone'

A Jackson Laboratory research team led by Professor Patsy Nishina, Ph.D., has identified a mutation in a gene that's essential for correct protein-processing in cells. Defects in protein folding are associated with a variety ...

Tiny channels carry big information

They say it's the little things that count, and that certainly holds true for the channels in transmembrane proteins, which are small enough to allow ions or molecules of a certain size to pass through, while keeping out ...

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. ...

'Prima donna' protein doesn't work well in pairs

A new study by Rice University bioengineers finds that the workhorse proteins that move cargo inside living cells behave like prima donnas. The protein, called kinesin, is a two-legged molecular machine. Rice's scientists ...

Team reveals all three structures of single transporter protein

A team of researchers from the Universities of Leeds, Oxford and Imperial College London have captured the 3D atomic models of a single transporter protein in each of its three main structural states, a goal of researchers ...
