== Publication Abstract from PubMed ==
The analysis of the interaction of threose 4-phosphate and 2-deoxyerythrose 4-phosphate with 3-deoxy-D-arabino-heptulosonate 7-phosphate synthase (DAH7PS) reveals previously unrecognised mechanistic differences between the DAH7PS-catalysed reaction and that catalysed by the closely related enzyme, 3-deoxy-D-manno-octulosonate 8-phosphate synthase (KDO8PS).

Mechanistic divergence of two closely related aldol-like enzyme-catalysed reactions.,Ahn M, Pietersma AL, Schofield LR, Parker EJ Org Biomol Chem. 2005 Nov 21;3(22):4046-9. Epub 2005 Oct 6. PMID:16267580<ref>PMID:16267580</ref>
