Abstract
Assessment of specific activity of riboflavin synthase and the level of riboflavin accumulation in strains with a 110-nucleotide deletion in the regulatory region of the riboflavin operon showed that this deletion specified semi-constitutive expression of the operon. This was assumed to be connected with the elimination of three nucleotides from a potential transcription antiterminator.
摘要
对核黄素操纵子调控区有110个核苷酸缺失的菌株中核黄素合酶的比活性和核黄素积累水平进行评估，结果表明该缺失导致了操纵子的半组成型表达。据推测，这与从一个潜在的转录抗终止子中消除三个核苷酸有关。
