Protein Family Models

This is a family of bacterial proteins involved in cellulose biosynthesis. (Roemling U. and Galperin M.Y. "Bacterial cellulose biosynthesis. Diversity of operons and subunits" (manuscript in preparation)). A second component of the extracellular matrix of the multicellular morphotype (rdar) of Salmonella typhimurium and Escherichia coli is cellulose. The family does contain a P-loop sequence motif suggesting a nucleotide binding function, but this has not been confirmed. [1]. 11260463. The multicellular morphotypes of Salmonella typhimurium and Escherichia coli produce cellulose as the second component of the extracellular matrix. Zogaj X, Nimtz M, Rohde M, Bokranz W, Romling U;.

This HMM describes an N-terminal region of homology share by two different classes of chain length determinant proteins (also known as polysaccharide co-polymerases) and by membrane-bound tyrosine kinases such Etk, involved in the polysaccharide export.
