Alignment analysis of NlxA and its homologues. Multiple alignments of NlxA with its homologues indicate the presence of a conserved motif specific for rhamnosyltransferase in NlxA. Only part of the alignment is shown. The names and GenBank accession numbers of the proteins are given. The nine amino acid residues which were identified by Steiner et al. (2010) as a binding signature of the substrate of deoxythymidinediphosphate‐β‐l‐rhamnose of WsaF are underlined.
