Bacterial cellulose biosynthesis: diversity of operons, subunits, products, and functions

Highlights • Cellulose is produced by a wide variety of environmental and pathogenic bacteria. • There are at least four distinct types of cellulose biosynthesis and export operons. • Cellulose is a key component of bacterial biofilms, and it regulates virulence. • Some cellulose synthase subunits h...

Zusammenfassung:	Highlights • Cellulose is produced by a wide variety of environmental and pathogenic bacteria. • There are at least four distinct types of cellulose biosynthesis and export operons. • Cellulose is a key component of bacterial biofilms, and it regulates virulence. • Some cellulose synthase subunits have known structures, others remain uncharacterized. • The properties of cellulose fibers make cellullose an attractive material for bionanotechnology.
