^a,b,cRef. Table 1 for gene segment annotations and names of homologues proteins in MRV, ARV and GCRV. Identity values are from separate pairwise alignments of the protein sequences.

^dValue from a manually adjusted pairwise alignment of the two proteins.

^fGCRV does not appear to have a cell attachment protein homologue to σ1/σC.
