CRYSTALLIZATION (Commentary)
ORGANISM
UNIPROT
LITERATURE
DtsR1 is crystallized by the sitting-drop vapour-diffusion method using polyethylene glycol 6000 as a precipitant
-
5S-subunit, native, with His-tag and selenomethionine-protein with His-tag. Crystallization of native 5S subunit requires addition of lithium sulfate, with in turn prevents crystallization of His-tagged subunit
-
central 12S hexameric core, in complex with substrate methylmalonyl-CoA. Structure shows two stacked trimers, and a domain duplication in the monomer
of 5S metalloenzyme subunit, free and in complex with substrate pyruvate, product oxaloacetate, or inhibitor 2-ketobutyrate. Dimer of beta8alpha8 barrels with active site cobalt ion
