1.3.99.17 additional information the gene cluster involved in quinoline degradation is transcribed from the quinoline-dependent promoters PoxoO, Porf3, PqorM, and PoxoR in the presence of oxoS. The oxoS gene coding for a quinoline-responsive transcriptional activator of the XylS family is expressed independently of quinoline -, 671438 1.3.99.17 synthesis production of uracil in supernatant of resting cells with a yield of more than 98% -, 655595
