Inverted membrane vesicles prepared from E. coli cells overexpressing E. coli K-12 BcsA and BcsB can synthesize cellulose in the presence of c-di-GMP (Omadjela, 2013). The bcsQ' domestication in-frame stop codon pseudogene defect in K-12 strain W3110 has been repaired, restoring cellulose production, colony morphology, biofilm architecture, and the divergent bcs operons' functions to a presumably wildtype status (Serra, 2013). BcsA has a C-terminal PilZ domain; the PilZ domain of YcgR has been implicated in cyclic-di-GMP binding. The presence of an in-frame stop codon mutation in the bcsQ' gene abolishes cellulose production and bcs divergent operon function in E. coli K-12.
