text E.coli bacterial cellulose synthase (Bcs) complex polymerizes glucose moieties from cytosolic UDP-glucose, releasing the polysaccharide into periplasmic space (Zogaj et al., 2001; Morgan et al., 2012). Bcs is a megadalton-sized secretory macrocomplex with a multimeric, layered, and asymmetric architecture. The core of the complex's stoichiometry is BcsR2Q2AB(5-6)E2 (Abidi et al., 2021; reviewed in Römling & Galperin, 2015). In a following reaction, the exported cellulose s modified with phosphoethanolamine (pEtN), producing pEtN cellulose. pEtN cellulose and curli fibers are essential components of the E.coli biofilm, a nano-composite ?building material? which confers tissue-like properties, i.e., cohesion, elasticity, and stability (Serra et al., 2013).
