Crystallization and preliminary crystallographic analysis of DtsR1 a carboxyltransferase subunit of acetyl-CoA carboxylase from Corynebacterium glutamicum

摘要

DtsR1, a carboxyltransferase subunit of acetyl-CoA carboxylase derived from Corynebacterium glutamicum, was crystallized by the sitting-drop vapour-diffusion method using polyethylene glycol 6000 as a precipitant. The crystal belongs to the trigonal system with space group R32 and contains three subunits in the asymmetric unit. A molecular-replacement solution was found using the structure of transcarboxylase 12S from Propionibacterium shermanii as a search model.
