Protein
Glutamine synthetase cytosolic isozyme 1-2
Gene
GLN1-2, GSR, RGS8, Os03g0223400, LOC_Os03g12290, OJ1743A09.19
Organism
Oryza sativa subsp. japonica (Rice)
Status
Reviewed - Annotation score: 4 out of 5 - Experimental evidence at protein leveli

Functioni

Catalytic activityi

ATP + L-glutamate + NH3 = ADP + phosphate + L-glutamine.

Kineticsi

Measured at pH 7.8 and 30 degrees Celsius for all experiments.

  1. KM=2.1 mM for glutamate1 Publication
  2. KM=73 µM for ammonium
  3. KM=530 µM for ATP

Vmax=94.7 nmol/sec/mg enzyme with glutamate as substrate

Vmax=98.1 nmol/sec/mg enzyme with ammonium as substrate

Vmax=109.1 nmol/sec/mg enzyme with ATP as substrate
