Abstract:
Protein logic gates are made from autoregulated fusion proteins comprising an output domain and a plurality of input domains, wherein at least one of the input domains is heterologous to the output domain, and the input domains interact with each other to allosterically and external, ligand-dependently regulate the output domain. The output domain may be constitutively active, and in the absence of the ligand, the input domains interact to inhibit the output domain. The activity of the output domain is user discretionary, and may include activities that are catalytic, label-generative, metabolic-regulative, apototic, specific-binding, etc. Multiple input domains can cooperatively regulate the fusion protein in a wide variety of functionalities, including as an OR-gate, an AND-gate, and an AND-NOT-gate. The gates may be incorporated into cells and therein used to modulate cell function.

International Classification:
C12N 15/01 C12N 15/70 C12N 1/21 C12N 15/11
US Classification:
435441, 536 231, 4353201, 43525233
Abstract:
The present invention provides for a recombinant nucleic acid comprising a nucleotide sequence comprising a plurality of constructs, wherein each construct independently comprises a nucleotide sequence of interest flanked by a pair of recombinase recognition sequences. Each pair of recombinase recognition sequences is recognized by a distinct recombinase. Optionally, each construct can, independently, further comprise one or more genes encoding a recombinase capable of recognizing the pair of recombinase recognition sequences of the construct. The recombinase can be an orthogonal (non-cross reacting), site-selective recombinase (OSSR).

In the meantime, there's plenty of work to be done before yeast is synthesising morphine at any kind of scale, said University of California, Berkeley, bioengineer John Dueber, lead author of the study in Nature Chemical Biology, who praised the new study as a "solid addition to the scientific liter

Could Genetic Engineering Make Non-Addictive Heroin?
John Dueber, a bioengineering professor at the University of California, Berkeley and one of the authors of the Nature Chemical Biology study, explains that synthetic molecules can be engineered to target certain cell receptors and not others. For example, in the case of morphine, this molecule can
What you really want to do from a fermentation perspective is to be able to feed the yeast glucose, which is a cheap sugar source, and have the yeast do all the chemical steps required downstream to make your target therapeutic drug, says John Dueber, the studys principal investigator and an assi

Home-Brewed Opiates Made Possible By Genetically Engineered Yeast
We need a common regulatory effort from governments, law officials and the scientific community to prevent misuse and allow the research to continue, John Dueber from UC Berkeley, who led one of the research teams, said, in the statement. The field is moving surprisingly fast, and we need to be o

Homebrewed morphine? It's now possible, say researchers
UC Berkeley bioengineer John Dueber worked with microbiologist Vincent Martin at Concordia University in Montreal to pick up on previous work involved in decoding a 15-step chemical pathway in the poppy plant. The goal of such work has been to figure out a way to feed sugar to microbes -- like yeast
University of California, Berkeley bioengineer John Dueber teamed up with microbiologist Vincent Martin at Concordia University in Montreal, to overcome that hurdle by replicating the early steps in the pathway in an engineered strain of yeast.

Heroin could be as easy to make as beer in the future
Its easy to point to heroin; thats a concrete problem, says bioengineer John Dueber of the University of California, Berkeley, who led the latest research. The benefits are less visible. They are going to greatly outweigh the negative, but its hard to describe them.
Now the pieces just need to get connected up and inserted into one yeast strain, says John Dueber, who led the study. "It's not going to be easy to do that," he says. "But if a talented lab focused on the goal, we're looking at about two to three years."
