Glyphosine inhibits maize leaf phosphoenolpyruvate carboxylase

Plant & Cell Physiology 28(2): 375-378

Glyphosine inhibits maize leaf phosphoenolpyruvate carboxylase

Glyphosine [N,N-bis-(phosphonomethyl) glycine] inhibited maize leaf P-enolypyruvate carboxylase competitively with respect to P-enolpyruvate. The inhibition was dependent on glyphosine concentration and pH. Glycine, but not glucose-6-phosphate, protected the enzyme from the effect of glyphosine. A related compound, glyphosate [N-(phosphonomethyl) glycine], produced little or no inhibition. P-enolpyruvate carboxylase could be one of the targets of glyphosine action, causing growth inhibition as reported (Croft, S.M., C.J. Arntzen, L.N. Vanderhoef and C.S. Zettinger (1974) Biochim. Biophys. Acta 335: 211-217).
