摘要
A prokaryote type glutamine synthetase (GS) was purified from a bialaphos (BA)-producing organism, Streptomyces hygroscopicus SF1293 (SF1293). The GS (GS I) consisted of a 55,000 dalton subunit, and its N-terminal amino acid sequence was similar to that of S. coelicolor GS. GS I was highly sensitive to GS inhibitor phosphinothricin (PPT). An increase of GS activity was observed accompanied by BA accumulation. © 1990.
