Abstract Conventional bivalent antibodies against cell surface receptors often initiate unwanted signal transduction by crosslinking two antigen molecules. Biparatopic antibodies (BpAbs) bind to two different epitopes on the same antigen, thus alteri

Spiroplasma, which are known pathogens and commensals of arthropods and plants, are helical-shaped bacteria that lack a peptidoglycan layer. Spiroplasma swim by alternating between left- and right-handed helicity. Of note, this system is not related

The bacterial flagellar MS ring is a core transmembrane complex within the flagellar basal body. Here, cryoEM analysis suggests that the MS ring is formed by 34 full-length FliF subunits, with 23- and 11-fold subsymmetries in the inner and middle M r

In the basal body of the bacterial flagellum, the LP ring acts as a bushing supporting the distal rod for its rapid and stable rotation. Here, Yamaguchi et al. present the electron cryomicroscopy structure of the LP ring around the rod, shedding ligh

The bacterial flagellar hook is a molecular universal joint that connects the rotary motor and long helical propeller of the bacterial flagellum. Here the authors present the 3.6 Å resolution cryo-EM structure of the native supercoiled Salmonella ho

The bacterial flagellum is a motile organelle that enables bacterial movement. Here the authors explain how the structurally similar flagellum components FlgG and FlgE can give rise to distinct macrostructures—the rod and hook—through subtle diff

ABSTRACT The flagellar motor can spin in both counterclockwise (CCW) and clockwise (CW) directions. The flagellar motor consists of a rotor and multiple stator units, which act as a proton channel. The rotor is composed of the transmembrane MS ring m
