Fitting a right hand in a left-handed mitten

Many biomolecules come in two versions that are each other's mirror image, like a left and a right hand. Cells generally use the left-hand version of amino acids to produce proteins, and uptake mechanisms were thought to ...

Multiple modes for selectivity of transmembrane transport

LMU researchers utilized a biophysical approach to understand how bacterial import proteins bind and selectively convey their cargoes across membranes. The results reveal an unexpectedly wide variety of transfer mechanisms.

New insight into unique sugar transport in plants

Sugar transport through sugar transport proteins (STP) is unique to plants, and is important for the proper development of plant organs such as pollen. STPs are also used to concentrate sugars in specific tissues like fruit, ...

How plants bind their green pigment chlorophyll

Chlorophyll is the pigment used by all plants for photosynthesis. There are two versions, chlorophyll a and chlorophyll b. These are structurally very similar to one another but have different colors, blue-green and yellowish ...

This RNA-based technique could make gene therapy more effective

Delivering functional genes into cells to replace mutated genes, an approach known as gene therapy, holds potential for treating many types of diseases. The earliest efforts to deliver genes to diseased cells focused on DNA, ...
