Nanofiber with Alternating Peptides

Caption

It's well established that peptides can self-assemble into nanofibers composed of beta-sheets. However, that self-assembly has previously involved identical copies of the same molecule -- molecule A connects to another molecule A. New work proves not only that alternating peptides can create these beta sheets -- in an ABAB pattern -- but why it happens. This image is an adaptation of computer simulation of the CATCH(+) and CATCH(-) mixture of peptides.
