From Zhang, et al., (2012).
A recent study reports the coupling of stress signals to a switch that turns off the synthesis of a protein of interest. The authors used biological standard parts to build their genetic circuit.


The Keasling group recently published a study where they introduce the so called “Dynamic Sensor-Regulator System” for metabolic engineering. This sensor is a transcription factor that responds to the presence of a particular intermediate metabolite of a metabolic pathway and regulates the metabolic flow.


A recent study reports the development of polymerizable GFP

A recent study reports the calculation of the evolutionary rate covariation (ERC) from proteomic data of 18 different yeast species. The interpretation of this data may help to assign uncharacterized proteins to functional groups and determine pathway connections.

A genomic-scale model of Pichia stipitis metabolism has been developed and validated, along with an update of the model of P. pastoris.
