TABLE 1.

Kinetic parameters of various ADP-Glc PPase enzymes for substrates in the synthetic direction

The S_0.5 values for ATP, Mg²⁺, and Glc-1-P for representative bacterial, unicellular algae, and plant homotetrameric and heterotetrameric proteins studied to date are shown. Stu indicates S. tuberosum; Ota indicates O. tauri; Eco indicates E. coli; Syn indicates Synochocystis; Ana indicates Anabaena, and Cre indicates C. reinhardtii. APS1 and APL1–4 are from A. thaliana.
