Kdo-8-P synthesis in the T-DNA insertion AtkdsA1-S, AtkdsA2-S, and AtkdsA2-V null mutants. (a) Comparison of HPLC profiles obtained with a standard of Kdo derivatized with DMB, DMB-derivatized cytosolic monosaccharides extracted from wild-type WS A. thaliana leaves, wild-type Nicotiana tabacum leaves, and AtkdsA2-V mutant leaves. The arrow points out the specific peak of DMB-derivatized Kdo. (b) HPLC analysis of DMB-derivatized cytosolic monosaccharides extracted from AtkdsA1-S and AtkdsA2-S mutant leaves. The arrow points out the specific peak of DMB-derivatized Kdo, and the DMB-derivatized N-acetyl neuraminic acid (NeuAc), used as an internal standard for quantification of Kdo, is indicated.
