FIGURE 1.
Lysine 19 is a conserved residue in GLYATs in several species. Alignment of the first ∼24 amino acids of GLYATs in the indicated species was carried out using the ClustalW method. The conserved lysine 19 residue is shown in bold (note this residue is an arginine in hGLYATL1). There is a serine (Ser-20) adjacent to lysine 19 in most species. L1, like-1; L2, like-2.
