Long coiled helices stack side by side in this AcrAB-TolC efflux pump protein, the molecular machine bacteria use to push antibiotics out of the cell. Ribbon-like spirals form the tall channel, looping strands connect the segments, and a ribbed barrel structure sits at one end where the pump crosses both bacterial membranes. Organic and intricate, it gives a cell biology or microbiology class a tangible look at antibiotic resistance, and stands out as a sculptural piece on a science shelf.
