Pyruvic Acid 146-154 phosphoenolpyruvate carboxylase 2 Zea mays 156-159 15667207-1 2005 Pyruvate phosphate dikinase (PPDK) reversibly catalyzes the conversion of ATP, phosphate, and pyruvate into AMP, pyrophosphate, and phosphoenolpyruvate (PEP), respectively. Pyruvic Acid 94-102 phosphoenolpyruvate carboxylase 2 Zea mays 153-156 14684927-1 2004 Pyruvate phosphate dikinase (PPDK) from maize catalyzes the reversible conversion of ATP, orthophosphate and pyruvate to AMP, pyrophosphate and PEP. Pyruvic Acid 109-117 phosphoenolpyruvate carboxylase 2 Zea mays 144-147 1321659-1 1992 Formate is an alternate substrate for bicarbonate in the reaction with PEP catalyzed by phosphoenolpyruvate carboxylase from Zea mays, producing formyl phosphate and pyruvate. Pyruvic Acid 99-107 phosphoenolpyruvate carboxylase 2 Zea mays 71-74 1633157-8 1992 These results are consistent with a mechanism in which carboxylation of PEP occurs via attack of the enolate of pyruvate on CO2 rather than carboxy phosphate. Pyruvic Acid 112-120 phosphoenolpyruvate carboxylase 2 Zea mays 72-75 16665477-8 1987 A positive relationship between levels of PGA and those of pyruvate during steady-state photosynthesis under various conditions suggests that an elevated concentration of PGA increases the carbon input into the C(4) cycle through the conversion of PGA to PEP and consequently the level of total intermediates of the C(4) cycle can be raised to mediate higher photosynthesis rate. Pyruvic Acid 59-67 phosphoenolpyruvate carboxylase 2 Zea mays 255-258 33016576-6 2021 Flux from malate via pyruvate to PEP remained low, commensurate with the low NADP-malic enzyme activity observed in the transgenic lines. Pyruvic Acid 21-29 phosphoenolpyruvate carboxylase 2 Zea mays 33-36 29327510-6 2018 Further, the detective ZmSTK1 or ZmSTK2 was associated with decreased activity of enolases and also reduced downstream metabolite contents, which enolases are involved in glycolytic pathway, such as phosphoenolpyruvate (PEP), pyruvate, ADP/ATP, starch, glucose, sucrose and fructose. Pyruvic Acid 210-218 phosphoenolpyruvate carboxylase 2 Zea mays 220-223
