The Anabaena sp. PCC 7120 ( Anabaena ) coiled‐coil‐rich proteins ZicK and ZacK are strictly interdependent for the assembly of protein filaments in vitro and in vivo . Both proteins are involved in the manifestation of the linear multicellular Anabaena phenotype, with deletion of the coding genes resulting in a zigzagged cell filament phenotype.
