Crystal structure of Seabream Antiquitin and Elucidation of its substrate specificityCrystal structure of Seabream Antiquitin and Elucidation of its substrate specificity
Structural highlights
FunctionEvolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedThe crystal structure of seabream antiquitin in complex with the cofactor NAD(+) was solved at 2.8A resolution. The mouth of the substrate-binding pocket is guarded by two conserved residues, Glu120 and Arg300. To test the role of these two residues, we have prepared the two mutants E120A and R300A. Our model and kinetics data suggest that antiquitin's specificity towards the substrate alpha-aminoadipic semialdehyde is contributed mainly by Glu120 which interacts with the alpha-amino group of the substrate. On the other hand, Arg300 does not have any specific interaction with the alpha-carboxylate group of the substrate, but is important in maintaining the active site conformation. The crystal structure of seabream antiquitin reveals the structural basis of its substrate specificity.,Tang WK, Wong KB, Lam YM, Cha SS, Cheng CH, Fong WP FEBS Lett. 2008 Sep 3;582(20):3090-6.
