Popis: |
Cell-free systems from the bacteria Escherichia coli and Klebsiella planticola that were incubated with 13 C labeled pyruvate and D-glyceraldehyde synthesized 5-hydroxypentane-2,3-dione (laurencione) along with 1-deoxy-D- threo -pentulose (1-deoxy-D-xylulose). Both compounds showed identical labeling patterns, indicating that the C 5 skeletons were derived from the condensation of (hydroxyethyl)thiamin on D-glyceraldehyde. Conversion of [5,5- 2 H 2 ]deoxyxylulose into laurencione by a cell-free system from E. coli showed that the α-dione is obtained from the pentulose by water elimination. |
