Molecular Cloning, Expression and Enzymatic Assay of Pteridine Reductase 1 from Iranian Lizard Leishmania

Background: Currently, there are no effective vaccines against leishmaniasis, and treatment using pentavalent antimonial drugs is occasionally effective and often toxic for patients. The PTR1 enzyme, which causes antifolate drug resistance in Leishmania parasites encoded by gene pteridine reductase 1 (ptr1). Since Leishmania lacks pteridine and folate metabolism, it cannot synthesize the pterid...

Molecular characterization of a Campylobacter jejuni lipoprotein with homology to periplasmic siderophore-binding proteins.

A genomic library of Campylobacter jejuni (NCTC 11351) was used to identify genes which could confer a hemolytic phenotype to Escherichia coli. Accordingly, when transformants were screened on blood plates, hemolytic colonies appeared at a frequency of 3 x 10(-4). The gene conferring the hemolytic activity was identified by subcloning and was found to be responsible for the phenotype of all hem...

Analysis of nitrate reductase mRNA expression and nitrate reductase activity in response to nitrogen supply

Nitrate is one of the major sources of nitrogen for the growth of plants. It is taken up by plant roots and transported to the leaves where it is reduced to nitrite in the. The main objective of this research was to investigate stimulatory effects of sodium nitrate, potassium nitrate, ammonia and urea on the production/generation of the nitrate reductase mRNA in Triticum aestivum plants. The pl...

Characterization of the biochemical properties of Campylobacter jejuni RNase III

Campylobacter jejuni is a foodborne bacterial pathogen, which is now considered as a leading cause of human bacterial gastroenteritis. The information regarding ribonucleases in C. jejuni is very scarce but there are hints that they can be instrumental in virulence mechanisms. Namely, PNPase (polynucleotide phosphorylase) was shown to allow survival of C. jejuni in refrigerated conditions, to f...

Isolation, molecular cloning and expression analysis of Aeluropus littoralis Monodehydroascorbate reductase (MDHAR) gene under salt stress

Plants are naturally exposed to frequent changes in environmental conditions such as salt stress affecting their growth and development, and consequently a considerable reduction in total productivity. Monodehydroascorbate reductase (MDHAR), a key enzyme in ascorbate-glutathione cycle, serves as an important antioxidative enzyme in scavenging of reactive oxygen spices (ROS). In this study, ...
