    Protein Summary

    The gene TM1468 from Thermotoga maritima encodes a putative fatty-acid binding domain protein (NP_229268), from a well-conserved among bacteria DegV family PF02645 COG1307. STRING genome context analysis provides a reliable hit (score 0.98) based on neighbourhood, gene fusion, and co-ocurrence with the uncharacterized protein TM1772. 

    SCOP classifies 1vpv in the alpha/beta class, DAK1/DegV-like superfamily, DegV-like family. DALI top hits are with the DegV family proteins PDB:2dt8 (Z=35), PDB:3fys (Z=33), the APC36103 protein PDB:1pzx (Z=32) and the SPY1493 protien PDB:2g7z (Z=32). Weaker hits are observed with the dihydroxyacetone kinases PDB:3ct4 and PDB:2iu4 (Z=16).

    The structure of TM1468 protein had been previously solved in a different crystal form and resolution (1MGP). Both solved structures of the TM1468 protein contain co-crystallized palmitic acid, which is consistent with its putative fatty-acid binding function. The TM1468 structure is in a closed conformation, which is probably induced by palmitate binding.

    The fold type of the TM1468 is similar to that of lipoate-protein ligase A from E.coli 1X2G (SufE/NifU fold.)  Lipoate-protein ligase A (LplA) catalyzes the formation of lipoyl-AMP from lipoate and ATP and then transfers the lipoyl moiety to a specific lysine residue on the acyltransferase subunit of α-ketoacid dehydrogenase complexes and on H-protein of the glycine cleavage system.
