Figure 2
The three-dimensional structure of unGlnK and adGlnK from C. glutamicum. (a) Structure of an unGlnK monomer shown in a cartoon representation. The side chain of Tyr51, which is located in the T-loop (residues 37–55), as well as the phosphate ion bound in the ATP-binding pocket, is shown in a stick representation and labeled accordingly. (b) Structure of the unGlnK trimer. Primes and double primes denote residues from the second and third protomers, respectively. (c) Structure of one adGlnK monomer. The side chain of the adenylylated Tyr51, as well as the AMP bound in the ATP-binding pocket, is highlighted in a stick representation. (d) Structure of the adGlnK trimer. |
