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

Краткое описание

Polyphenoloxidases (PPOs), including tyrosinases and laccases, are ubiquitous metalloenzymes, which have several copper-binding sites. The enzymes cause undesirable browning in vegetables, mushrooms, and fruits, and melanin production of animals. Agaricus brasiliensis is an edible mushroom whose water extracts show biological response modifier effects. Since cold-water extracts of the mushroom fruiting body turn brown on incubation, it has been speculated that the mushroom contains significant amounts of PPOs. Our group has already shown that cold-water extracts indicated PPO activity. Therefore, we cloned a cDNA coding for a PPO from A. brasiliensis cultivated outside in the field. First, a partial sequence of the PPO gene was amplified by reverse transcription (RT)-PCR from the total RNA isolated from A. brasiliensis. Since two copper-binding motifs are well conserved among the PPO amino acid sequences from fungi, two degenerate primers used for the RT-PCR were designed and synthesized based on these sequences. The nucleotide sequence of the amplified fragment showed 83% identity with the corresponding sequence of the A. bisporus PPO gene. Full-length cDNA of the PPO gene was amplified from a cDNA library of A. brasiliensis. Obtained DNA sequences indicated that the amplified cDNA contained an open reading frame of 1731 nucleotides that encoded 576 amino acid residues. Homology search analysis showed that the deduced amino acid sequence was most similar to that of A. bisporus PPO, with 75% identity. The A. brasiliensisfull-length PPO gene was also amplified from the genomic DNA and then se-quenced. Five introns were found within the gene.
