Diffraction data have been obtained (but the solved structure not yet deposited) for a ''Listeria monocytogenes'' sequence of 307 residues, pI 5.2, with an E value of 1.6e-05, though only 21% sequence identity. Diffraction-quality crystals (but not yet diffraction data) have not been obtained for any sequence with such a low E value.

''E. coli'' dnaC (245 residues, pI 9.4) has been crystallized by RIKEN Structural Genomics Initiative (Japan), but the crystals may not be of diffraction quality. It has been cloned, expressed as a soluble protein, and purified (but not yet crystallized) by 3 Structural Genomics Groups (RIKEN Structural Genomics Initiative (Japan), Montreal-Kingston Bacterial Structural Genomics Initiative, Midwest Center for Structural Genomics), as have several proteins with >40% sequence identity. So there is reason for optimism that either a crystal structure, or a more suitable template for homology modeling, will be forthcoming soon. One might consider contacting the groups who have reported purification of dnaC to inquire about progress, and possibly request priority for dnaC.
