Details | UMP-Kinase from B. subtilis has a sequence identity of 40% to T1668 and is known to exist as a hexamer (a trimer of dimers). This fact has been experimentally tested via Gel filtration(C. Gagyi et. al. Eur. J. Biochem. 270, 3196-3204). However biologically active species are monomers. The hexamer can be generated by symmetry operation -X+1,-Y,Z. |

MR phases were used to locate Se sites. Experimental phases were calculated using a Se-substructure containing 26 Se sites. Nine sulfate groups were located. Sulfates D4 - D9 mimic phosphate group of ATP at the ATP binding pocket.
