Sequence alignment of pseutarin C nonenzymatic subunit with mammalian FV. The deduced amino acid sequence of pseutarin C nonenzymatic subunit (AY168281) is compared with bovine FV (Q28107), human FV (P12259), and mouse FV (T42764) sequences. Sequence alignment was done using the GeneDoc program. Gaps (–) have been inserted for optimal alignment. Identical amino acid residues are shaded in black. In B domain, amino acid residues identical in all 3 mammalian sequences are shaded in gray.
