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: 1.2 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: 1.4 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: 0.3 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: 0.00066 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: 0.34 SJR: 0.274 SNIP: 0.41 CiteScore™:: 2.8 H-Index: 37

摘要

A ribonuclease was purified from dry fruiting bodies of the wild edible mushroom Lepista personata (LPR) to 259-fold with a specific activity of 280 U/mg. The purification protocol involved ion-exchange chromatography on DEAE-cellulose, CM-cellulose and SP-sepharose, followed by size exclusion chromatography on Superdex 75. LPR is a homodimeric protein with a molecular weight of 27.8 kDa as determined by SDS-PAGE and by gel filtration. Three inner peptide sequences for LPR were obtained by LC-MS-MS analysis. It demonstrated the optimum pH of 4.0 and temperature optimum of 60°C. The specificity ribonuclease potencies order toward polyhomoribonucleotides was poly C > poly A > poly G > poly U. The ribonuclease inhibited HIV-1 reverse transcriptase with an IC50 of 0.53 μM.
