Comparison of arginine biosynthesis and Thermus lysine biosynthesis related proteins. (A) Phylogenetic relationships among the amino acid sequence encoded in the argC gene ofT. thermophilus and the related sequences. A total of 267 amino acid sites were considered without gap regions in alignment. The bar indicates 10% difference of amino acid sequence. The DAD accession nos. used in this phylogenetic analysis are D64004-19-1, U48355-1-1,X52834-1-1, X99978-2-1, AL031541-2-1, M83659-1-1, Z85982-15-1,AF049897-1-1, M21446-1-1, AE000861-7-1, U67552-4-1, AE000961-28-1,AE000761-6-1, Y10525-2-1, AP000007-35-1, Z69727-9-1, X98880-1-1,U18813-19-1, and L27746-1-1. (B) Phylogenetic relationships among the amino acid sequence encoded in the argB gene ofT. thermophilus and the related sequences. A total of 157 amino acid sites were considered without gap regions in alignment.
