    Protein Summary

    Gene TM1367 from Thermotoga maritima encodes the NP_229168 protein that belongs to the DUF369 (PF04126) family. Its structure (2ka0) reveals an atypical cyclophilin (peptidylprolyl cis-trans isomerase) fold [Ref]. Homologous sequences to TM1367 are found in bacteria and archaea only. TM1367 has sequence similar to proteins from COG2164 (Uncharacterized conserved protein) , COG4925 (Uncharacterized conserved protein), and COG4070 (predicted peptidyl-prolyl cis-trans isomerase (rotamase), cyclophilin family). 

    2ka0 belongs to the SCOP cyclophilin-like superfamily, TM1367-like family. 2ka0 (or its crystal structure PDB:1zx8) Dali hits are with PDB:2nnz (Z-scr=16), PDB:3kop (Z-scr=14), and cyclophilin B PDB:1j2a (Z-scr=11). Several conserved residues are part of putative ligand binding cleft (Trp39, Glu42, Tyr44, Trp69, Cys76, Phe78, Pro91, and Val95. In the structural alignment, residues Cys76 and Glu42 are not superimposed in the similar protein structures (i.e.: PDB structures: 2cpl and 1x7f).
