Protein Family Models

The D-amino acid transferases (D-AAT) are required by bacteria to catalyse the synthesis of D-glutamic acid and D-alanine, which are essential constituents of bacterial cell wall and are the building block for other D-amino acids. Despite the difference in the structure of the substrates, D-AATs and L-ATTs have strong similarity. Crystal structure. [1]. 7626635.

branched-chain amino acid aminotransferase catalyses the transamination of the branched-chain amino acids leusine, isoleucine and valine to their respective alpha-keto acids, alpha-ketoisocaproate, alpha-keto-beta-methylvalerate and alpha-ketoisovalerate

Among the class IV aminotransferases are two phylogenetically separable groups of branched-chain amino acid aminotransferase (IlvE). The last common ancestor of the two lineages appears also to have given rise to a family of D-amino acid aminotransferases (DAAT). This model represents the IlvE family more strongly similar to the DAAT family.
