Enzymes within biochemical pathways are often colocalized,
yet the consequences of specific spatial enzyme arrangements
remain poorly understood. We study the impact of enzyme
arrangement on reaction efficiency within a
reaction-diffusion model. The optimal arrangement
transitions from a cluster to a distributed profile as a
single parameter, which controls the probability of...

Recent developments of single molecule detection techniques
have made possible to observe transcription and translation,
one event at a time, in live cells. Here, we report
measurements of time intervals between consecutive
transcription events from several promoters in live
Escherichia coli cells, which were obtained using a
single-RNA detection technique by MS2-GFP tagging....

Evolution by natural selection is a learning algorithm of
remarkable power. We propose a simple, general abstract
model of evolution for which the mutation-selection
equilibrium can be given in closed form for arbitrary
fitness functions. The model is a modification of the Moran
process for evolution with overlapping generations.
Computational models of evolution -- such as...

In different biological processes, cells move in a
coordinated way. Several experiments have quantitatively
investigated this phenomenon. We will describe a simple
model of interacting random walkers that we have developed
to phenomenologically describe these results, based on data
obtained in P Silberzan's lab (Institut Curie, Paris). The
model serves to suggest some biological...
