yeast-GEM: The consensus genome-scale metabolic model of Saccharomyces cerevisiae

Description

This repository contains the current consensus genome-scale metabolic model of Saccharomyces cerevisiae. It is the continuation of the legacy project yeastnet. For the latest release please click here.

Citation

If you use yeast-GEM please cite the yeast8 paper:

Lu, H. et al. A consensus S. cerevisiae metabolic model Yeast8 and its ecosystem for comprehensively probing cellular metabolism. Nature Communications 10, 3586 (2019). https://doi.org/10.1038/s41467-019-11581-3.
Additionally, all yeast-GEM releases are archived in Zenodo, for you to cite the specific version of yeast-GEM that you used in your study, to ensure reproducibility. You should always cite the original publication + the specific version, for instance:

The yeast consensus genome-scale model [Lu et al. 2019], version 8.3.4 [Sánchez et al. 2019], was used.

Installation

Required software - User:

Matlab user:
- A functional Matlab installation (MATLAB 7.3 or higher).
- The COBRA toolbox for MATLAB.
Python user: Python 3.4, 3.5, 3.6 or 3.7

Required software - Contributor:

Both of the previous Matlab requirements.
The RAVEN toolbox for MATLAB.
A git wrapper added to the search path.

NOTE: You also require git lfs if you wish to run locally any of the following two memote commands:

memote run
memote report history

This is because results.db (the database that stores all memote results) is tracked with git lfs.

Dependencies - Recommended Software:

For Matlab, the libSBML MATLAB API (version 5.17.0 is recommended).
Gurobi Optimizer for any simulations.

Installation instructions

For users: Clone it from main in the Github repo, or just download the latest release. If you work in python, please create an environment with all requirements:

pip install -r requirements/requirements.txt  # installs all dependencies
touch .env                                    # creates a .env file for locating the root

For contributors: Fork it to your Github account, and create a new branch from develop.

Usage

Make sure to load/save the model with the corresponding wrapper functions!

In Matlab:

cd ./code
model = loadYeastModel(); % loading
saveYeastModel(model);    % saving

In Python:

import code.io as io
model = io.read_yeast_model() # loading
io.write_yeast_model(model)   # saving

Online visualization/simulation

You can visualize selected pathways of yeast-GEM and perform online constraint-based simulations using Caffeine, by creating a simulation with the latest yeast-GEM version available, and choosing any S. cerevisiae map (currently only iMM904 maps are available). Learn more about Caffeine.
Additionally, you can interactively navigate model components and visualize 3D representations of all compartments and subsystems of yeast-GEM at Metabolic Atlas. Learn more about Metabolic Atlas.
