Abstract

Mutations in capR or capT cause derepression of the enzymes of the gal operon. The gal-specific messenger ribonucleic acid is directly proportional to the gal enzyme levels in wild type, capR, and capT strains. These results indicate that capR and capT control the gal operon at the transcriptional level.

摘要

capR或capT基因发生突变会导致半乳糖操纵子的酶去阻遏。在野生型、capR和capT菌株中，半乳糖特异性信使核糖核酸与半乳糖酶水平成正比。这些结果表明，capR和capT在转录水平上控制半乳糖操纵子。
