San Diego’s Molecular Assemblies has raised $12.2 million to commercialize a new way of producing DNA, in what could turbocharge work across life sciences.

Scientists for decades have crafted DNA sequences chemically for everything from drug development to agriculture. But chemical synthesis has limitations. It’s toxic. And it can be slow.

Molecular Assemblies wants to take DNA writing to the next level through what’s called “enzymatic DNA synthesis.” It generates long and accurate DNA sequences, which could aid an array of scientists.

“It will open doors into areas that the chemical method can’t touch,” Molecular Assemblies CEO Michael Kamdar told the San Diego Business Journal.

Kamdar said he has been approached by companies seeking lengthier DNA sequences for new vaccines and hardier crops, as two examples. Molecular’s first commercial product is 18 to 24 months away, according to Kamdar.

Data Storage

Longer term, its DNA technology could even store data — an alternative to hard drives or the cloud. Deploying DNA as a natural storage system has gained traction with an explosion of data threatening to overwhelm infrastructure that can’t hold all of it.

A first step in validating the idea, scientists at Molecular last year converted a text message into binary data, encoded the message as DNA data, and then wrote the sequence as DNA using Molecular’s enzymatic synthesis. Eventually, the end result was a readable text message, albeit stored as DNA.

Molecular said it marked the first time data was stored and retrieved as DNA, something academics up until that point considered mere possibility.

The Competition

Enzymatic DNA synthesis was a blip on the scientific consciousness three years ago, but now the landscape includes Molecular Assemblies and a half-dozen other companies, including DNA Script.

Recently, Kamdar participated on a panel with some of those companies.

“There’s a spirit of comradery because we’re all interested in seeing enzymatic DNA synthesis get ahead,” Kamdar said. “But then there’s obviously the competitive side.”

Broadening Its Prospects

What differentiates Molecular? The company’s website highlights its patent portfolio. And Kamdar said some companies are chasing one submarket while Molecular envisions serving varying industries.

“For us we’d like to be able to provide DNA for all those areas, as opposed to just specifically focus on one,” he said.

The market for traditional chemical synthesis, he said, is about $1 billion annually. But Kamdar envisions the industry mushrooming in size with the advent of enzymatic DNA synthesis.

Christopher Voigt, a synthetic biologist at the Massachusetts Institute of Technology in Cambridge, earlier this year affirmed the industry’s potential in the journal Nature.

“Any technology that can make that faster is going to be very valuable,” Voigt said. He did not return a request for comment on which company might be leading the race in enzymatic synthesis.

Molecular has 18 employees, more than double its workforce a year ago. After the $12.2 million fundraise — which came as a Series A round — the company is slated to add a couple more workers by year’s end.

In addition, the company will relocate to Alexandria GradLabs, where growing biotechs with early-stage funding can share resources.

Molecular wants to clear up a bottleneck in DNA synthesis.

The rise of DNA sequencing accelerated the rate at which scientists read DNA, but the underlying process of writing DNA has been essentially the same for decades.

The Founders

Knowing this well are William Efcavitch and Curt Becker, who together founded Molecular Assemblies in 2013. The pair commercialized chemical DNA synthesis some 30 years ago, fueling what was a nascent biotech industry.

But the drawbacks of chemical synthesis — including high volumes of toxic waste — steered them toward the enzymatic approach.

Chemical synthesis can only generate about 100 nucleotide bases, which means DNA sequences have to be stitched together to assemble a gene. This produces errors, demanding heaps of extra processing time.

Kamdar took the helm in 2016. Having spent his career in the pharmaceutical industry, he was enticed by a relatively short timeline to market and a wide reach.

“When you’re doing therapeutics, you’re focused on one market and one drug and it’s a long time horizon to get to market. This is a shorter cycle and it has the ability to play into synthetic biology, into life sciences, into data, into agriculture.”

Saying something similar was Mike Kime, managing director of iSelect Fund, which led the recent funding round.

He said in a statement the company’s platform “has the potential to fundamentally transform how we create DNA on demand to enable breakthroughs in life sciences, information storage, synthetic biology, and electronics.”
