<p>An operon encoding 4 proteins required for bacterial cellulose biosynthesis(bcs) in <taxon tax_id="28448">Acetobacter xylinus</taxon> (Gluconacetobacter xylinus) has been isolated via genetic complementationwith strains lacking cellulose synthase activity [<cite idref="PUB00007624"/>]. Nucleotide sequence analysis showed the cellulose synthase operon to consist of 4 genes, designated bcsA, bcsB, bcsC and bcsD, all of which are required for maximal bacterial cellulose synthesis in A. xylinum.</p><p>The calculated molecular mass of the protein encoded by bcsC is 141.0kDa [<cite idref="PUB00007624"/>]. The function of BcsC is unknown. The sequence shares a high degree of similarity with <taxon tax_id="562">Escherichia coli</taxon> YhjL.</p> Cellulose synthase, subunit C
