enzax 0.1.1

Differentiable models of enzyme-catalysed reaction networks

Enzax

Enzax is a library of automatically differentiable equations and solvers for modelling networks of enzyme-catalysed reactions, written in JAX.

Enzax provides straightforward, fast and interoperable access to the gradients of realistic metabolic network models, allowing you to incorporate these models in your MCMC and machine learning algorithms when you want to, for example, predict the effect of down-regulating an enzyme on the yield of a fermentation experiment.

Installation

pip install enzax

Usage

Find a kinetic model's steady state

from enzax.examples import methionine
from enzax.steady_state import solve_steady_state
from jax import numpy as jnp

guess = jnp.full((5,) 0.01)

steady_state = solve_steady_state(
    methionine.parameters, methionine.unparameterised_model, guess
)

Find a steady state's Jacobian with respect to all parameters

import jax
from enzax.examples import methionine
from enzax.steady_state import solve_steady_state
from jax import numpy as jnp

guess = jnp.full((5,) 0.01)

jacobian = jax.jacrev(solve_steady_state)(
    methionine.parameters, methionine.unparameterised_model, guess
)
