zDB
A comparative genomics database
Homology search
Blast an input sequence against the genomes of the database. You can select among blastn, blastp, or the six-frame translation-based approaches, blastx and tblastn.
Orthology
Get a list of Orthogroups, COGs, Kegg Orthologs, Pfam domains shared by selected genomes and absent in others and display the result in a Venn diagram for an easier understanding or visualize their presence or absence in heatmaps. Identify orthogroups presenting more than one homolog in genomes of interest and draw barcharts to visualize the distribution of selected categories among the genomes.
Annotations
Get a list of Orthogroups, COGs, Kegg Orthologs, Pfam domains shared by selected genomes and absent in others and display the result in a Venn diagram for an easier understanding or visualize their presence or absence in heatmaps. Identify orthogroups presenting more than one homolog in genomes of interest and draw barcharts to visualize the distribution of selected categories among the genomes.
Genome alignments
Generate a clickable version of circos plot indicating the presence/absence of homologous proteins in one or multiple genomes, the GC content and navigate to the description of the locus tags of interest.
Align target genomic regions of two or more genomes and plot them.
Metabolism
Discover which metabolic pathways are present in the genomes. KEGG categories can be investigated checking which KEGG entries are present in each KEGG module. Entries can be visualized in lists or used to generate an annotated phylogeny. In addition, you can visualize in the KEGG maps which genes of a specific pathway are carried by a genome of interest.
Your database has been generated including the following features:
- Orthologous proteins identified with OrthoFinder
- Detailed annotation of proteins based on:
- -COG (clusters of orthologous groups)
- -Pfam (protein families)
- - KEGG (Kegg orthologs)
- - SwissProt (manually annotated proteins)
- Precomputed phylogenetic reconstructions of orthologous groups
- Kegg maps visualization
- Genomes alignments can be visualized with Circos and selected regions can be plotted and compared
