| Description | Aminotransferases share certain mechanistic features with other pyridoxal-phosphate dependent enzymes, such as the covalent binding of the pyridoxal-phosphate group to a lysine residue. On the basis of sequence similarity, these various enzymes can be grouped [ ] into subfamilies.One of these, called class-IV, currently consists of proteins of about 270 to 415 amino-acid residues that share a few regions of sequence similarity. Surprisingly, the best conserved region does not include the lysine residue to which the pyridoxal-phosphate group is known to be attached, in ilvE, but is located some 40 residues at the C terminus side of the pyridoxal-phosphate-lysine. The D-amino acid transferases (D-AAT), which are among the members of this entry, 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 [ , ]. The proteins in this entry are about 270 to 415 amino-acid residues and all share a few regions of sequence similarity. Surprisingly, the best conserved region does not include the lysine residue to which the pyridoxal-phosphate group is known to be attached, in IlvE. The region used for this signature pattern is located some 40 residues at the C terminus side of the PlP-lysine. |
