Prochlorococcus sp. | For MED4 wild-type, by 60 min post treatment the transcript levels of phrB, mutT and radA drop | down |
Prochlorococcus sp. | is more highly expressed in MED4 UV-hyper-resistant strain relative to MED4 wild-type. In the absence of UV treatment, in steady-state growth, MED4 UV-hyper-resistant strain has considerably higher levels of phrB and mutT transcripts relative to MED4 wild-type. For MED4 wild-type, phrB, mutT and radA are rapidly upregulated, showing elevated transcript levels by 5 min post treatment. For MED4 UV-hyper-resistant strain, phrB, mutT and radA are slightly upregulated following UV irradiation, with transcripts decreasing slightly between 5 and 60 min | up |
General Information | Comment | Organism |

physiological function | PhrB breaks pyrimidine dimers caused by UV exposure, using energy from visible light in the process of photoreactivation. UV-hyper-resistant strain contains a single mutation: a 1 bp deletion in the intergenic region directly upstream of the mutT-phrB operon, encoding nudix hydrolase and photolyase | Prochlorococcus sp. |
