cellulose biosynthesis~Cellulose, a homopolymer of glucose featuring uniform beta-1,4 linkages, is synthesized in bacteria by cellulose synthase [1,2]. Bacterial cellulose may have further modifications such as acetylation. The synthase consists of two subunits (or domains in the frequent cases where it is encoded as a single polypeptide), a catalytic domain and regulatory domain which binds the allosteric activator cyclic-di-GMP. The protein is membrane-embedded and probably assembles into multimers such that the individual cellulose strands can self-assemble into multi-strand fibrils. The purpose of the endoglucanase which is always present in the same operon with the synthase is not known. Control of the levels of c-diGMP is via pppGpG cyclases and c-diGMP and pGpG phosphodiesterases. All genomes expressing this system have numerous cyclase and phosphodiesterase domain proteins and multiple regulatory circuits are possible. In E. coli strains, at least three regulatory systems are indicated [3], whose genes typically are not clustered with the biosynthetic genes. |
