    Protein Summary

    Gene Ta0195 from Thermoplasma acidophilum encodes protein NP_393673 that belongs to the large family of OsmC-like proteins (PF02566, COG1765, and COG1764). Proteins from this family are present mostly in bacteria, but also in protists, slime molds and fungi, are involved in oxidative / osmotic stress response and hydroperoxide detoxification. Interestingly, eukaryotic proteins from this family do not form a common sub-tree and appear to represents independent gene transfer events. In the vicinity of gene Ta0195, a death associated protein kinase related protein is found with score 0.8 (Ta0196)

    According to SCOP, 2onf and its structural similar neighbors (PDB structures [Dali Z score]: PDB:2pn2 [Z=15], PDB:1ml8 [Z=15], PDB:2d7v [Z=16], PDB:1n2f [Z=14], PDB:1qwi [Z=14], PDB:1vla [Z=12], and PDB:2opl [Z=11]) belong to the OsmC-like fold from the alpha+beta class. Other proteins from this family solved by JCSG are Thermotoga maritima protein TM0919 (PDB:1vla, topsan) and Psychrobacter arcticus protein Psyc_0566 (PDB:2pn2, topsan).
