This domain is often found next to the Pfam:PF02254 domain. The exact function of this domain is unknown. It has been suggested that it may bind an unidentified ligand [1]. The domain is predicted to adopt an all beta structure [1].
This domain is found at the N-terminal end of K(+)/H(+) antiporter subunit KhtT from Bacillus subtilis (KhtT) and similar proteins mainly found in bacteria. KhtT is required for activity of the potassium/proton antiporter KhtU. It is involved in prot ...
This domain is found at the N-terminal end of K(+)/H(+) antiporter subunit KhtT from Bacillus subtilis (KhtT) and similar proteins mainly found in bacteria. KhtT is required for activity of the potassium/proton antiporter KhtU. It is involved in protection of the cell from methylglyoxal, a toxic by-product of glycolysis [3-5]. This domain adopts an unusual fold, comprised by a twisted five antiparallel beta-sheet followed by an alpha-helix [6].
