Characterizing Phage Genomes for Therapeutic Applications

PMCID: 5923482
PMID: 29642590
DOI: 10.3390/v10040188

[…] redicted ORF was queried by BLASTx against NCBI’s non-redundant (nr) protein sequences. Peptide sequences for each predicted ORF also underwent homology searches using BLASTp against nr, PhAnTOME [], pVOGs [] and the PHASTER Prophage/Virus databases []. The following threshold values were applied in general. Putative ORFs with 50–70% sequence identity [] to a given gene were assigned “putative.” W […]


Extension of the viral ecology in humans using viral profile hidden Markov models

PLoS One
PMCID: 5774701
PMID: 29351302
DOI: 10.1371/journal.pone.0190938

[…] other tools and protocols available for detecting viral genomes in microbial genomic data. The tool Virsorter[] uses a reference set consisting of viral proteins from the RefSeq database (similar to pVOGS[]) but this tool and its database are mainly designed to detect viruses that infect microbes (archaea and bacteria).In a published protocol for virus sequence discovery for metagenomic data, Pae […]


Comparative Analysis of 37 Acinetobacter Bacteriophages

PMCID: 5795418
PMID: 29295549
DOI: 10.3390/v10010005

[…] and motifs identified using pfam_scan.pl against the Pfam31 database and InterProScan 5.25-64 [,]. Translated ORF sequences were also searched against hidden Markov model profiles downloaded from the prokaryotic Virus Orthologous Groups database [] using hmmscan [] with an e-value cut-off of 1 × 10−3. Matches to pVOG profiles were considered significant at an e-value of ≤ 1 × 10−15 and ≥35% covera […]


Comparative Genomics of Bacteriophage of the Genus Seuratvirus

Genome Biol Evol
PMCID: 5758909
PMID: 29272407
DOI: 10.1093/gbe/evx275
call_split See protocol

[…] 3.6.0 using assembler only options (). The resulting genomes were annotated with Prokka 1.12 using a custom database of proteins extracted from all current viral genomes [April 2017] as well as using pVOGS (; ). Single gene phylogenetic analysis was carried out using TranslatorX to build nucleotide alignments using MAFFT, based on the aligned amino acid sequence (). Phylogenetic trees were constru […]


How to Name and Classify Your Phage: An Informal Guide

PMCID: 5408676
PMID: 28368359
DOI: 10.3390/v9040070

[…] .Comparison of protein groups, predicted proteomes, identification of signature genes: CoreGenes 3.5 [,], Roary (core and accessory genome analysis) [], prokaryotic Virus Orthologous Groups resource (pVOGs) [].Multiple alignment and/or phylogenetic analyses: Clustal Omega [], MUSCLE [], phylogeny.fr [], MEGA6 [], FastTree [].Visualization: progressiveMAUVE [], Easyfig [], BRIG [].
