Sugiharto et al., Plant Physiol 1992
:
Addition of methionine sulfoximine ( MSX ), a specific inhibitor of glutamine synthetase, inhibited the nitrate dependent increase of PEPC and CA mRNA but did not affect the glutamine dependent increase of PEPC and CA mRNA levels
Schuller et al., Plant Physiol 1990
:
PEPC ( 1 ) was activated more than fourfold by 2.0 millimolar glutamine and sixfold by 2.0 millimolar dihydroxyacetone phosphate (DHAP) at a subsaturating PEP concentration of 0.625 millimolar
