X-RAY STRUCTURE OF THE DIHYDROXYACETONE KINASE FROM ESCHERICHIA COLI
Overview
Dihydroxyacetone (Dha) kinases are homologous proteins that use different, phosphoryl donors, a multiphosphoryl protein of the, phosphoenolpyruvate-dependent carbohydrate:phosphotransferase system in, bacteria, ATP in animals, plants, and some bacteria. The Dha kinase of, Escherichia coli consists of three subunits, DhaK and DhaL, which are, colinear to the ATP-dependent Dha kinases of eukaryotes, and the, multiphosphoryl protein DhaM. Here we show the crystal structure of the, DhaK subunit in complex with Dha at 1.75 A resolution. DhaK is a homodimer, with a fold consisting of two six-stranded mixed beta-sheets surrounded by, nine alpha-helices and a beta-ribbon covering the exposed edge strand of, one sheet. The core of the N-terminal domain has an alpha/beta fold common, to subunits of ... [(full description)]
