Structural and phylogenetic relationships among Bacteria and Eukaryota were analyzed by examining 292 methionine adenosyltransferase (MAT) amino acid sequences with respect to the crystal structure of this enzyme established for Escherichia coli and rat liver. Approximately 30% of MAT residues were found to be identical in all species. Five highly conserved amino acid sequence blocks did not vary in the MAT family. We detected specific structural features that correlated with sequence… CONTINUE READING
