Parameter

get_specie_reference_from_sbml(specie_id)[source]

Get the compound/enzyme associated with an SBML species by its ID

Parameters:specie_id (str) – ID of an SBML species
Returns:
Return type:tuple
Raises:ValueError – if the species is not a compound or enzyme, no species with id = specie_id exists, or no compartment with name = compartment_name exists
infer_compound_structures_from_names(compounds)[source]

Try to use PubChem to infer the structure of compounds from their names

Notes: we don’t try look up structures from their cross references because SABIO has already gathered all structures from their cross references to ChEBI, KEGG, and PubChem

Parameters:compounds (list of Compound) – list of compounds
load_compounds(compounds=None)[source]

Download information from SABIO-RK about all of the compounds stored in the local sqlite copy of SABIO-RK

Parameters:compounds (list of Compound) – list of compounds to download
Raises:Error – if an HTTP request fails
load_content()[source]

Download the content of SABIO-RK and store it to a local sqlite database.

load_kinetic_law_ids()[source]

Download the IDs of all of the kinetic laws stored in SABIO-RK

Returns:list of kinetic law IDs
Return type:list of int
Raises:Error – if an HTTP request fails or the expected number of kinetic laws is not returned
load_kinetic_laws(ids)[source]

Download kinetic laws from SABIO-RK

Parameters:ids (list of int) – list of IDs of kinetic laws to download
Raises:Error – if an HTTP request fails
load_missing_enzyme_information_from_html(ids)[source]

Loading enzyme subunit information from html

Parameters:ids (list of int) – list of IDs of kinetic laws to download
load_missing_kinetic_law_information_from_tsv(ids)[source]

Update the properties of kinetic laws in the local sqlite database based on content downloaded from SABIO in TSV format.

Parameters:ids (list of int) – list of IDs of kinetic laws to download
load_missing_kinetic_law_information_from_tsv_helper(tsv)[source]

Update the properties of kinetic laws in the local sqlite database based on content downloaded from SABIO in TSV format.

Note: this method is necessary because neither of SABIO’s SBML and Excel export methods provide all of the SABIO’s content.

Parameters:tsv (str) – TSV-formatted table
Raises:ValueError – if a kinetic law or compartment is not contained in the local sqlite database
normalize_kinetic_laws(ids)[source]

Normalize parameter values

Parameters:ids (list of int) – list of IDs of kinetic laws to download
normalize_parameter_value(name, type, value, error, units, enzyme_molecular_weight)[source]
Parameters:
  • name (str) – parameter name
  • type (int) parameter type (SBO term id) –
  • value (float) – observed value
  • error (float) – observed error
  • units (str) – observed units
  • enzyme_molecular_weight (float) – enzyme molecular weight
Returns:

normalized name and

its type (SBO term), value, error, and units

Return type:

tuple of str, int, float, float, str

Raises:

ValueError – if units is not a supported unit of type

parse_complex_subunit_structure(text)[source]

Parse the subunit structure of complex into a dictionary of subunit coefficients

Parameters:text (str) – subunit structure described with nested parentheses
Returns:dictionary of subunit coefficients
Return type:dict of str, int

  • bool: if True, the enzyme is wild type
  • str: variant
Return type:tuple
Raises:ValueError – if the enzyme name is formatted in an unsupport format
