The glutamyl-tRNA synthetase (gltX) gene from Pseudomonas aeruginosa was identified. A plasmid containing a 2.3-kb insert complemented the temperature-sensitive gltX mutation of Escherichia coli JP1449, and GltX activity was demonstrated. The inferred amino acid sequence of this gene showed 50.6% identity with GltX from Rhizobium meliloti.
鉴定出了铜绿假单胞菌的谷氨酰胺-tRNA合成酶(gltX)基因。一个含有2.3 kb插入片段的质粒互补了大肠杆菌JP1449的温度敏感型gltX突变,并证明了GltX活性。该基因推导的氨基酸序列与苜蓿根瘤菌的GltX有50.6%的同一性。
