Photorepair of ultraviolet-induced petite mutational damage in Saccharomyces cerevisiae requires the product of the PHR1 gene.
نویسندگان
چکیده
A wild-type (phr+) diploid yeast strain showed photorepair of petite mutational damage, whereas a photoreactivation-deficient (phr1/phr1) diploid strain did not, indicating that the PHR1 gene product was required for mitochondrial photorepair.

Promoter elements of the PHR1 gene of Saccharomyces cerevisiae and their roles in the response to DNA damage.
The PHR1 gene of Saccharomyces cerevisiae encodes the apoenzyme for the DNA repair enzyme photolyase. PHR1 transcription is induced in response to 254 nm radiation and a variety of chemical damaging agents. We report here the identification of promoter elements required for PHR1 expression. Transcription is regulated primarily through three sequence elements clustered within a 120 bp region imm...
متن کاملIsolation, Subtype Determination, Cloning and Expression of HBsAg Gene from an Iranian Carrier in Saccharomyces cerevisiae
The Hepatitis B Surface antigen ( HBsAg) gene was isolated from an Iranian HBeAg positive carrier by PCR. The gene was cloned in pUC19 for sequencing and pYES2 for expression in Saccharomyces cerevisiae, which pNF1 and pDF3 constructs were made respectively. The sequencing data showed that the isolated HBsAg gene shared more than 90% homology with the ayw subtype. The pDF3 was transferred into ...
متن کاملTrichoderma atroviride PHR1, a fungal photolyase responsible for DNA repair, autoregulates its own photoinduction.
The photolyases, DNA repair enzymes that use visible and long-wavelength UV light to repair cyclobutane pyrimidine dimers (CPDs) created by short-wavelength UV, belong to the larger photolyase-cryptochrome gene family. Cryptochromes (UVA-blue light photoreceptors) lack repair activity, and sensory and regulatory roles have been defined for them in plants and animals. Evolutionary considerations...
متن کاملPhosphorylation of Rph1, a damage-responsive repressor of PHR1 in Saccharomyces cerevisiae, is dependent upon Rad53 kinase.
Rph1, a Cys2-His2 zinc finger protein, binds to an upstream repressing sequence of the photolyase gene PHR1, and represses its transcription in response to DNA damage in Saccharomyces cerevisiae. In this report, we have demonstrated that the phosphorylation of Rph1 protein was increased in response to DNA damage. The DNA damage-induced phosphorylation of Rph1 was missing in most damage checkpoi...

Background and Aim: Pseudomonas aeruginosa is an important ubiquitous and especially common pathogen in the hospital. Exotoxin A that encoded by exoA gene has a role in pathogenesis of this bacterium. Today, probiotics are widely used in the treatment and prevention of diseases. The present study aimed to study the Saccharomyces cerevisiae S3 effect on the expression of exoA gene. Materials an...
