Default NMR structure of the ribosomal protein L23 from Thermus thermophilus.

NMR structure of the ribosomal protein L23 from Thermus thermophilus.

Related Articles NMR structure of the ribosomal protein L23 from Thermus thermophilus.

J Biomol NMR. 2003 Jun;26(2):131-7

Authors: Ohman A, Rak A, Dontsova M, Garber MB, Härd T

The ribosomal protein L23 is a component of the large ribosomal subunit in which it is located close to the peptide exit tunnel. In this position L23 plays a central role both for protein secretion and folding. We have determined the solution structure of L23 from Thermus thermophilus. Uncomplexed L23 consists of a well-ordered part, with four anti-parallel beta-strands and three alpha-helices connected as beta-alpha-beta-alpha-beta-beta-alpha, and a large and flexible loop inserted between the third and fourth beta-strand. The observed topology is distantly related to previously known structures, primarily within the area of RNA biochemistry. A comparison with RNA-complexed crystal structures of L23 from T. thermophilus, Deinococcus radiodurans and Haloarcula marismourtui, shows that the conformation of the well-ordered part is very similar in the uncomplexed and complexed states. However, the flexible loop found in the uncomplexed solution structure forms a rigid extended structure in the complexed crystal structures as it interacts with rRNA and becomes part of the exit tunnel wall. Structural characteristics of importance for the interaction with rRNA and with the ribosomal protein L29, as well as the functional role of L23, are discussed.

Active site dynamics in NADH oxidase from Thermus thermophilus studied by NMR spin relaxation
Active site dynamics in NADH oxidase from Thermus thermophilus studied by NMR spin relaxation Abstract We have characterized the backbone dynamics of NADH oxidase from Thermus thermophilus (NOX) using a recently-developed suite of NMR experiments designed to isolate exchange broadening, together with 15N R 1, R 1Ï? , and {1H}-15N steady-state NOE relaxation measurements performed at 11.7 and 18.8 T. NOX is a 54 kDa homodimeric enzyme that belongs to a family of structurally homologous flavin reductases and nitroreductases with many potential biotechnology applications. Prior studies...
