FIG. 6. Superimposition of the active site of the
ttGlnAT·kynurenine complex model onto ttGlnAT·3PP.
The residues that represent the ttGlnAT· kynurenine
complex and ttGlnAT·3PP are shown in brown and deep blue,
respectively. Kynurenine and 3PP are represented by thick lines
in pale blue and brown. The oxygen and nitrogen atoms of
kynurenine and 3PP are colored red and deep blue, respectively.
The dotted lines (green) show the hydrogen bonding interactions
of the amino and carbonyl groups of the 3-anthraniloyl moiety of
kynurenine with Asp-113 and Tyr-57^*, respectively.
