Novel synthetic proteins rival their natural counterparts in proton transport

March 3, 2020

polymer membranes

Biological membranes, such as the "walls" of most types of living cells, primarily consist of a double layer of lipids, or "lipid bilayer," that forms the structure, and a variety of embedded and attached proteins with highly specialized functions, including proteins that rapidly and selectively transport ions and molecules in and out of the cell. Scientists have long sought to develop synthetic membranes that could match the selectivity and high-speed transport offered by their natural counterparts. Now a team led by University of California Berkeley researchers has designed a novel polymer that is as effective as natural proteins in transporting protons through a membrane. The results of their research were published in Nature.

Frances Arnold turns microbes into living factories

PASADENA, Calif. — The engineer’s mantra, said Frances Arnold, a professor of chemical engineering at the California Institute of Technology, is: “Keep it simple, stupid.” But Dr. Arnold, who last year became just the fifth woman in history to win the Nobel Prize in Chemistry, is the opposite of stupid, and her stories sometimes turn rococo.

Scientists use DNA origami to alter gene expression in plants

DNA origami could change the way we alter plants

new research reported from the lab of Markita Landry, a professor of chemical and biomolecular engineering at UC Berkeley, a team of scientists has taken an original approach of using DNA origami nanotechnology to slip through plant cell walls and graft small interfering RNA (siRNA) directly onto plant cells. Their research shows it is possible to directly silence genes in plants without damaging plant tissues, and without making any alterations to the plant’s genome.

Breakthrough Study of Cell Signaling Holds Promise for Immune Research and Beyond

NanoEP experiment

For the first time ever, scientists have imaged the process by which an individual immune system molecule is switched on in response to a signal from the environment, leading to the critical discovery that the activation process involves hundreds of proteins suddenly coming together to form a linked network through a process known as a phase transition.

Yeast produce low-cost, high-quality cannabinoids

February 27, 2019

Scientists in the lab of Jay Keasling grow marijuana chemicals using yeast UC Berkeley synthetic biologists have engineered brewer’s yeast to produce marijuana’s main ingredients—mind-altering THC and non-psychoactive CBD—as well as novel cannabinoids not found in the plant itself. Medical research on the more than 100 other chemicals in marijuana has been difficult, because the chemicals occur in tiny quantities, making them hard to extract from the plant. Inexpensive, purer sources—like yeast—could make such studies easier.
