FIG. 3.

Multiple amino acid sequence alignment of GcvT proteins from different organisms. (A) The accession numbers of the sequences are as follows: S. meliloti, AL591688; Agrobacterium, AE007869; E. coli, AP009048.1; Arabidopsis, AT1G11860; human, NM_000481; bovine, NM_177485. Sequences are aligned with the USDA257 GcvT sequence (GQ214396). Positions of amino acid identity are boxed. Multiple sequence alignment analysis was performed using the CLUSTAL W program from UniProt Knowledgebase (http://www.uniprot.org/). (B) Phylogenetic tree of GcvT. The scale shown in the phylogenetic tree represents the branch distance as the number of changes in character state between GcvT proteins from different organisms.
