    Protein gradients on the nucleoid position the carbon-fixing organelles of cyanobacteria

    Joshua S MacCready et al.
    Carboxysomes, the carbon-fixation machinery of cyanobacteria, are equidistantly-positioned by dynamic gradients of the protein McdA on the nucleoid that emerge through interaction with a previously unidentified carboxysome factor, McdB.
