FIG. 2.

Variants of the ED pathway in T. tenax. The enzymes identified in the T. tenax genome are shown in grey-shaded boxes, and the previously characterized GDH is shown in an open box. The central intermediate KDG of both variants is boxed. Closed arrows indicate the reactions of the nonphosphorylative version of the ED pathway; open arrows indicate the reactions of the semiphosphorylative version. Grey-shaded arrows mark reactions involved in both versions. For abbreviations of enzyme names, see Table 2.
