Abstract

A mutant of Escherichia coli K-12 isolated for temperature-sensitive growth was found to harbor an alteration in robosomal protein L9. Because the chromosomal location of the structural gene for this protein (rplI) was not known, we mapped the mutation by using various Hfr strains. The fine mapping of this gene by Plkc phage-mediated transductions has revealed that it forms a gene cluster at 94 min on the E. coli genetic map together with the genes coding for two other ribosomal proteins, S6 (rpsF) and S18 (rpsR). Furthermore, the region of the E. coli genetic map containing this cluster was found to be shorter than previously estimated by approximately 2 min.

摘要

一株为研究温度敏感生长特性而分离出的大肠杆菌K-12突变体，被发现其核糖体蛋白L9发生了改变。由于该蛋白（rplI）结构基因的染色体定位尚不清楚，我们利用各种高频重组（Hfr）菌株对该突变进行了定位。通过P1kc噬菌体介导的转导对该基因进行精细定位，结果表明它在大肠杆菌遗传图谱上94分钟处与编码另外两种核糖体蛋白S6（rpsF）和S18（rpsR）的基因形成一个基因簇。此外，发现大肠杆菌遗传图谱上包含该基因簇的区域比先前估计的短约2分钟。
