a
Homologies were determined with Gapped BLAST (3). Numbers shown are percentages of identity/percentages of similarity/numbers of amino acids in the region of homology.
b
The functions of these enzymes have been demonstrated to transfer d-rhamnose by means of an α-1,2 linkage or an α-1,3 linkage (37).
