Thermodynamic cost-controllability tradeoff in metabolic currency coupling
Jumpei F. Yamagishi, Tetsuhiro S. Hatakeyama
Cellular metabolism is globally regulated by various currency metabolites such as ATP, GTP, and NAD(P)H. These metabolites cycle between charged (high-energy) and uncharged (low-en…
Global Constraint Principle for Microbial Growth Law
Jumpei F. Yamagishi, Tetsuhiro S. Hatakeyama
Monod's law is a widely accepted phenomenology for bacterial growth. Since it has the same functional form as the Michaelis--Menten equation for enzyme kinetics, cell growth is oft…
Universal Transitions between Growth and Dormancy via Intermediate Complex Formation
Jumpei F. Yamagishi, Kunihiko Kaneko
A simple cell model consisting of a catalytic reaction network with intermediate complex formation is numerically studied. As nutrients are depleted, the transition from the expone…
Linear Response Theory of Evolved Metabolic Systems
Jumpei F. Yamagishi, Tetsuhiro S. Hatakeyama
Predicting cellular metabolic states is a central problem in biophysics. Conventional approaches, however, sensitively depend on the microscopic details of individual metabolic sys…
A geometric speed limit for acceleration by natural selection in evolutionary processes
Masahiro Hoshino, Ryuna Nagayama, Kohei Yoshimura +2
We derived a new speed limit in population dynamics, which is a fundamental limit on the evolutionary rate. By splitting the contributions of selection and mutation to the evolutio…
Chaos on a High-Dimensional Torus
Jumpei F. Yamagishi, Kunihiko Kaneko
Transition from quasiperiodicity with many frequencies (i.e., a high-dimensional torus) to chaos is studied by using -dimensional globally coupled circle maps. First, the existe…
The advantage of leakage of essential metabolites and resultant symbiosis of diverse species
Jumpei F Yamagishi, Nen Saito, Kunihiko Kaneko
Microbial communities display extreme diversity. A variety of strains or species coexist even when limited by a single resource. It has been argued that metabolite secretion create…
Symbiotic Cell Differentiation and Cooperative Growth in Multicellular Aggregates
Jumpei F Yamagishi, Nen Saito, Kunihiko Kaneko
As cells grow and divide under a given environment, they become crowded and resources are limited, as seen in bacterial biofilms and multicellular aggregates. These cells often sho…
