Abstract excerpt
Glutamine synthetase (GS; EC 6.3.1.2) is a key enzyme in nitrogen metabolism; it catalyzes the critical incorporation of inorganic ammonium into glutamine. Two full-length cDNAs that encode the rice (Oryza sativa) cytosolic glutamine synthetase1 genes (OsGS1;1 and OsGS1;2) were isolated from a Minghui 63 normalized cDNA library, and glnA encoding GS in Escherichia coli was isolated by PCR amplification....
