"Asymmetry Is the Rhythmic Expression of Functional Design," a Quotation from Jan Tschichold.

The outer membranes of Gram-negative bacteria provide a permeability barrier to antibiotics and other harmful chemicals. The integrity of this barrier relies on the maintenance of the lipid asymmetry of the outer membrane, and studies of suppressors of a decades-old mutant reveal that YejM plays a key regulatory role and provide a model for the maintenance of this asymmetry.
