Structure of tyrosine aminotransferase from Leishmania infantum

The structure of the tyrosine aminotransferase from the parasitic protozoa L. infantum was solved to 2.35 Å resolution. The difference in substrate specificity and enzymatic activity between leishmanial and mammalian TAT is explained based on the presence of two residues (Gln55 and Asn58).
