| Method |
Electron cryotomography. Primary source abstract: "Bacterial chemoreceptors cluster in highly ordered, cooperative, extended arrays with a conserved architecture, but the principles that govern array assembly remain unclear. Here [investigators] show images of cellular arrays as well as selected chemoreceptor complexes reconstituted in vitro that reveal new principles of array structure and assembly." |
| Comments |
P.1293 left column bottom paragraph: "In E. coli, transmembrane chemoreceptors form large and highly ordered arrays at the cell poles. Chemoreceptors are organized into trimers of dimers, and linked by CheW and CheA into a honeycomb lattice (refs 4, 5, 6 and primary source), with a 6:1:1 receptor/CheA/CheW stoichiometry in terms of monomers (primary source)." |
