introduction and aims: h. pylori has been implicated in peptic diseases, some with detrimental consequences such as ulcer or cancer. since considerable genetic heterogeneity has been observed within h. pylori population worldwide, it appears an ideal achievement to recruit pcr-based methods and design genetic markers which recognize isolates from normal and symptomatic individuals. in this stud...

Members of the RabGDI/REP family serve as multifunctional regulators of the Rab family of GTP binding proteins. Mutations in members of this family, such as REP-1, lead to abnormalities, including progressive retinal degradation (choroideremia) in humans. The crystal structures of the REP-1 protein in complex with monoprenylated or C-terminally truncated Rab7 proteins revealed that Rab7 interac...

Rab GTPases participating in the regulation of vesicle trafficking in eukaryotes are geranylgeranylated by the Rab geranylgeranyl transferase (RabGGTase) in complex with the Rab escort protein (REP). Here, we describe basic properties of the Arabidopsis thaliana REP (AthREP), first REP outside yeasts or metazoans to be characterized. GFP-tagged AthREP, as well as the geranylgeranylation activit...

The replication-associated protein (Rep) of geminiviruses is involved in several biological processes brought about by the presence of distinct functional domains. Recently, we have exploited the multifunctional character of the Tomato yellow leaf curl Sardinia virus (TYLCSV) Rep to develop a molecular interference strategy to impair TYLCSV infection. We showed that transgenic expression of its...

In the present study, Randomly Amplified Polymorphic DNA‌ (RAPD) and Repetitive Extragenic Palindromic sequence-based Polymerase Chain Reaction (REP-PCR) were used to characterize 131 isolates of Pasteurella multocida, originating from different healthy and diseased animal species obtained from several geographical regions of Iran. The RAPD and REP-PCR generated amplified products in the range ...

Repetitive-element PCR (rep-PCR) with primers based on repetitive extragenic palindromic (REP) and enterobacterial repetitive intergenic consensus (ERIC) repeated DNA sequences was used for genomic finger-printing of Bartonella species. This technique was applied by using either extracted genomic DNA or preparations of whole bacterial cells directly. PCR fingerprints with either the REP-based p...

32 Recently the DiversiLab (DL) system (bioMérieux) was developed as an automated platform that uses 33 rep-PCR technology for standardized, reproducible DNA fingerprinting of bacteria. The purpose of this 34 study was to evaluate the usefulness of DL rep-PCR for typing of Pseudomonas aeruginosa isolates. 35 The performance of DL rep-PCR was compared with that of pulsed-field gel electrophoresi...
