A Minimal
Cell Computer model of the JCVI-syn3A, the engineered
Mycoplasma single cell synthetic organism. |
|
Researchers at
the Carl Woese Institute for Genomic Biology used the the
JvC Institute synthetic Mycoplasma (JCVI-syn3.0) to
develop a three-dimensional, fully dynamic kinetic computer model of a living minimal cell that
mimics what goes on in the actual cell. THey usied the JCVI-syn3A Mycoplasma cells with its minimum 493 genes. The computer simulation maps out the precise location and chemical characteristics of thousands of cellular components in 3D space at an atomic scale. It tracks how long it takes for these molecules to diffuse through the cell and encounter one another, what kinds of chemical reactions occur when they do, and how much energy is required for each step. |

The model revealed
that the cell used the bulk of its
energy to import essential ions and molecules across its
cell membrane. The model also was used to calculate the natural lifespan of messenger RNAs and to reveal a relationship between the rate at which lipids and membrane proteins were synthesized and changes in membrane surface area and cell volume. The kinetic model opens a window on the inner workings of the cell, showing cell biologists how all of the components interact and change in response to internal and external cues. Toolkit |

The
properties of a cell spring from its genome and Venter
(2010 - JVCI-syn3.0) created a new cell by inserting a
synthetic genome into a bacterium. Now researchers around
the world are making genetically engineered organisms to
posses metabolic pathways capable of making
pharmaceuticals, hydrocarbon-based fuels, even
cyanobacteria that make diesel fuels from light, water and
CO2. Biologist can now turn to studying cells
than may be created through experimental manipulation
rather tahn studying only cell available in nature |
