== Publication Abstract from PubMed == | |||
Soluble diacylglycerol (DAG) kinases function as regulators of diacylglycerol metabolism in cell signaling and intermediary metabolism. We report the structure of a DAG kinase, DgkB from Staphylococcus aureus, both as the free enzyme and in complex with ADP. The molecule is a tight homodimer, and each monomer comprises two domains with the catalytic center located within the interdomain cleft. Two distinctive features of DkgB are a structural Mg2+ site and an associated Asp*water*Mg2+ network that extends toward the active site locale. Site-directed mutagenesis revealed that these features play important roles in the catalytic mechanism. The key active site residues and the components of the Asp*water*Mg2+ network are conserved in the catalytic cores of the mammalian signaling DAG kinases, indicating that these enzymes use the same mechanism and have similar structures as DgkB. | |||
Analysis of the Staphylococcus aureus DgkB structure reveals a common catalytic mechanism for the soluble diacylglycerol kinases.,Miller DJ, Jerga A, Rock CO, White SW Structure. 2008 Jul;16(7):1036-46. PMID:18611377<ref>PMID:18611377</ref> | |||
