<p>Sequences in this family of proteins belong to the polysaccharide export protein family, which includes the Wza [<cite idref="PUB00008202"/>] from <taxon tax_id="562">Escherichia coli</taxon>. This family of proteins are homologous to the EpsE protein of the methanolan biosynthesis operon of <taxon tax_id="94001">Methylobacillus sp. 12S</taxon> [<cite idref="PUB00021014"/>]. The distribution of this protein appears to be restricted to a subset of exopolysaccharide operons containing a syntenic grouping of genes including a variant of the EpsH exosortase protein [<cite idref="PUB00021014"/>]. Exosortase has been proposed to be involved in the targeting and processing of proteins containing the PEP-CTERM domain to the exopolysaccharide layer.</p> Polysaccharide export EpsE
