Family I aminotransferases. Selected sequences were aligned via the clustal algorithm and utilized for tree construction with the neighbor-joining method. The putative B. subtilis AspAT sequences are underlined, and the subfamily designations (as defined by Iraqui et al. [25a]) are shown on the base of the appropriate branches. The enzymes are abbreviated as follows: AspAT, aspartate aminotransferase; TyrAT, tyrosine aminotransferase; AVTA, alanine:valine aminotransferase; HisPAT, histidinol-phosphate aminotransferase; AlaAT, alanine aminotransferase; KynAT, kynurenine aminotransferase.
