Figure 1
(a) The reaction catalyzed by TAG. (b) TAG is mainly α-helical; a structural zinc ion (grey sphere) is a found in all homologues of the enzyme. 3-MeA is shown in stick representation, with C atoms coloured yellow, N atoms coloured blue and O atoms coloured red. (c) Difference Fo − Fc electron density contoured at 3σ for 3-MeA in the active site of TAG. (d) Difference Fo − Fc electron density contoured at 3σ for 3-MeA in the active site of Y16F-mutant TAG; C atoms are coloured pink. 3-MeA binds in a different orientation in the Y16F mutant. |
