The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 2.4 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 2.8 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.5 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00049 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.59 SJR: 0.429 SNIP: 0.507 CiteScore™:: 3.9 H-Index: 49

摘要

We have previously reported on cloning a DNA repair gene designated as uvr3 by virtue of its ability to phenotypically complement the UV sensitivity of mutant strain MBH3. Subsequently, we identified the uvr3 gene to be the uvrA gene (gene identification number HI0249) of Haemophilus influenzae Rd. The uvrA gene is a component of the UvrABC excision repair pathway.We studied molecular basis of the UV sensitivity of the MBH3 strain and identified a G®A transition at nucleotide position 2700 of the uvrA gene, altering the Trp-900 codon (TGG) to a nonsense codon (TGA). Thus, the UvrA protein produced in the mutant strain MBH3 is likely to be truncated and unable to carry out the UV-induced DNA repair, thereby rendering the strain UV sensitive.
