Selection for Replicases in Protocells [PDF]

open access: yesPLoS Computational Biology, 2013
We consider a world of nucleotide sequences and protocells. The sequences have the property of spontaneous self-replication. Some sequences - so-called replicases - have enzymatic activity in the sense of enhancing the replication rate of all (or almost all) sequences.

SYNCHRONIZATION PHENOMENA IN PROTOCELL MODELS [PDF]

open access: yesBIOMAT 2007, 2008
This work aims to consider simplified models of protocells in order to describe their general behaviors. The advantage of the modelling approach is that the early protocells of life-forms on Earth are not reproduced in the present time. However, the problem is considered as a right track to understand the origin of life as well as to work with more ...

Colony-like Protocell Superstructures [PDF]

open access: yesBiophysical Journal, 2021
Abstract We report the formation, growth, and dynamics of model protocell superstructures on solid surfaces, resembling single cell colonies. These structures, consisting of several layers of lipidic compartments enveloped in a dome-shaped outer lipid bilayer, emerged as a result of spontaneous shape transformation of lipid agglomerates

On Protocell "Computation" [PDF]

open access: yes, 2006
The EU FP6 Integrated Project PACE ('Programmable Artificial Cell Evolution') is investigating the creation, de novo, of chemical 'protocells'. These will be minimal 'wetware' chemical systems integrating molecular information carriers, primitive energy ...

Spatially Encoded Protocell Network for Non-Cascaded Parallel Biocomputation. [PDF]

open access: yesAdv Sci (Weinh)
A non‐cascaded, hydrogel‐based proteinosome computational platform is developed, in which redox‐responsive proteinosomes serve as local computing units within a shared reaction–diffusion field. Reductant inputs, countered by an auxiliary glucose gradient, regulate spatially patterned proteinosome disruption, and generate population‐level boundaries ...

Knitting a protocell

open access: yes, 2010
A protocell is defined as the earliest form of chemical system that can replicate itself. Although cells inevitably contain some form of metabolism to achieve this goal, the cell was originally thought of and thus named by its enclosing structure. We now know that the structure is built by a cellular metabolism which is regulated and produced by an ...

Photoactivated Signaling Networks using DNA-Based Synthetic Organelles as Biomimetic Protocells. [PDF]

open access: yesAngew Chem Int Ed Engl
Light‐triggered intercommunication between two types of organelle‐loaded liposomes lead to DNAzyme‐mediated on transcription‐guided structural reconfiguration of the organelles. ABSTRACT Membraneless organelles formed by phase‐separated nucleic acid or protein condensates play vital roles in regulating cellular functions.

Evolution of Proliferative Model Protocells Highly Responsive to the Environment

open access: yesLife, 2022
In this review, we discuss various methods of reproducing life dynamics using a constructive approach. An increase in the structural complexity of a model protocell is accompanied by an increase in the stage of reproduction of a compartment (giant ...
