This domain is found at the C-terminal end of Isocitrate dehydrogenase [NADP] from Rickettsia typhi and similar bacterial proteins. It is also found in the hypothetical protein TT1725 from Thermus thermophilus HB8. The presence of positively-charged residues in the alpha-1 helix suggests this region binds to a protein with a negatively charged region or to nucleic acids [1].	Domain
