[…] Only eukaryotic core α1,6-FucT sequences were considered for this study. Homologous fut8 sequences were searched by querying all genomic and expressed sequence tag (EST) divisions of the National Center for Biotechnology Information (NCBI database, Washington, DC, USA), as described previously for sialyltransferases , (). DNA and aa sequences were analyzed using DNA Strider . PSORT II ( was used for the prediction of protein localization sites in cells. Homology searches were performed using the BLAST program . Multiple sequence alignments of the 86 deduced aa sequences homologous to α1,6-fucosyltranferases were generated using ClustalW 2.0.8, Clustal Omega 1.1.0 or MAFFT, which are multiple sequence alignment programs available at Gblocks ( was used to select the 336/785 informative sites. Evolutionary analyses were conducted using the Neighbor Joining (NJ) and Maximum Likelihood (ML) methods implemented in MEGA 5.05 . The branch robustness was tested with 1050 bootstrap replicates. Conservation of synteny and gene order in the metazoan were visualized at the Genomicus web site (version 19.01) ( . […]
