==NMR structure of the unphosphorylated form of OdhI, OdhI.==
[[http://www.uniprot.org/uniprot/ODHI_CORGL ODHI_CORGL]] An essential component of the PknG signaling pathway. When unphosphorylated, it inhibits the activity of 2-oxoglutarate dehydrogenase. When phosphorylated it does not inhibit 2-oxoglutarate dehydrogenase.

== Publication Abstract from PubMed ==
The OdhI protein is key regulator of the TCA cycle in Corynebacterium glutamicum. This highly conserved protein is found in GC rich Gram-positive bacteria (e.g., the pathogenic Mycobacterium tuberculosis). The unphosphorylated form of OdhI inhibits the OdhA protein, a key enzyme of the TCA cycle, whereas the phosphorylated form is inactive. OdhI is predicted to be mainly a single FHA domain, a module that mediates protein-protein interaction through binding of phosphothreonine peptides, with a disordered N-terminal extension substrate of the serine/threonine protein kinases. In this study, we solved the solution structure of the unphosphorylated and phosphorylated isoforms of the protein. We observed a major conformational change between the two forms characterized by the binding of the phosphorylated N-terminal part of the protein to its own FHA domain, consequently inhibiting it. This structural observation corresponds to a new autoinhibition mechanism described for a FHA domain protein.
