Chalmers SysBio GEM in the form of gene-metabolite interactions

Description

Processing GEMs from Wang et al., 2021 (https://github.com/SysBioChalmers) to generate PKN for COSMOS

Usage

chalmers_gem_network(
  organism_or_gem = "Human",
  metab_max_degree = 400L,
  protein_ids = c("uniprot", "genesymbol"),
  metabolite_ids = c("hmdb", "kegg")
)

Arguments

`organism_or_gem`	Character or integer or list or data frame: either an organism (taxon) identifier or a list containing the “reactions“ data frame as it is provided by `chalmers_gem`, or the reactions data frame itself. Supported taxons are 9606 (Homo sapiens), 10090 (Mus musculus), 10116 (Rattus norvegicus), 7955 (Danio rerio), 7227 (Drosophila melanogaster) and 6239 (Caenorhabditis elegans).
`metab_max_degree`	Degree cutoff used to prune metabolites with high degree assuming they are cofactors (400 by default).
`protein_ids`	Character: translate the protein identifiers to these ID types. Each ID type results two extra columns in the output, for the "a" and "b" sides of the interaction, respectively. The default ID type for proteins is Esembl Gene ID, and by default UniProt IDs and Gene Symbols are included.
`metabolite_ids`	Character: translate the protein identifiers to these ID types. Each ID type results two extra columns in the output, for the "a" and "b" sides of the interaction, respectively. The default ID type for metabolites is Metabolic Atlas ID, and HMDB IDs and KEGG IDs are included.

Value

Data frame (tibble) of gene-metabolite interactions.
