1H, 15N and 13C backbone and side chain solution NMR assignments of the TPM domain-containing protein of the thermophilic bacterium Rhodothermus marinus

The InterPro family IPR007621 TPM_phosphatase is a widely conserved family of protein domains found in prokaryotes, plants and invertebrates. Despite similar predicted protein folding, members of this family are involved in different cellular processes. In recent years, the structural and biochemical characterization of evolutionarily divergent TPM domains has shown their ability to hydrolyze phosphate groups of different substrates. However, there are still inaccurate functional annotations and uncertain relationships between the structure and function of this domain family. We here report the H-1, C-13, and N-15 backbone and sidechain resonances of the TPM domain of a predicted TPM domain-containing protein of the thermophilic bacterium Rhodothermus marinus. These data will lay the groundwork for future NMR-based investigations, contributing to a thorough comprehension of the intricate aspects governing the interplay between structure and function of TPM domains. Additionally, they will unlock opportunities to explore dynamic structural changes, providing valuable insights into the molecular mechanisms underlying the evolutionary adaptations to extreme environmental conditions within this protein family.
