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 share this preference. Scientists have now shown that a prokaryotic transport protein can transport both versions of the amino acid aspartate with equal efficiency.
