Finding that this enzyme was helping a bacteria to break down, or digest, PET plastic, the researchers chose to "tweak" its structure by adding some amino acids, said John McGeehan, a professor at Portsmouth who co-led the work.
Lead scientist prof John McGeehan, from Portsmouth university, said: 'Serendipity often plays a significant role in fundamental scientific research, and our discovery is no exception.
The discovery is being hailed as potentially being the solution to the global plastic pollution crisis and is the first known protein capable of digesting polyethylene, one of the most commonly used plastics for consumer goods. "It means we won't need to dig up any more oil and, fundamentally, it should reduce the amount of plastic in the environment". But I believe there is a public driver here: "perception is changing so much that companies are starting to look at how they can properly recycle these".
The scientists reportedly used a super-powerful X-ray, about 10 billion times brighter than the Sun, to make an ultra-high-resolution 3D model of the Japanese enzyme called PETase. The newly discovered enzyme promises to recycle plastic bottles back into new clear plastic bottles, which would require much less virgin plastic. "It's great and a real finding".

After the stewards cleared the paper strands, they threw another round they held back in reserve to delay the second half even further.
Not that PETase is a slouch - as PET by itself takes centuries to naturally break down, and the enzyme enables the bacteria to shorten that to just a matter of days.
An worldwide team of researchers may have accidentally engineered an enzyme that could help mitigate the global plastic pollution crisis. During testing, the team unexpectedly improved the enzymes plastic-digesting abilities.
The paper, "Characterization and engineering of a plastic-degrading aromatic polyesterase", will be published this week in the Proceedings of the National Academy of Sciences (PNAS).
When the team tweaked the structure of the enzyme by adding some amino acids, tests showed that it made the molecule even better at breaking down PET plastic.

In 27 minutes, Mills mustered five points on 2-for-5 from the field, well down on his season average of ten points per game. A catalyst for Golden State was the surprise move from Steve Kerr to insert Andre Iguodala into the starting lineup.

Furthermore, efforts to recycle the abundance of these bottles have been limited by the technology available that can only re-use the plastic in a small range of products. But bacteria are far easier to harness for industrial uses. PET sinks in seawater but some scientists have conjectured that plastic-eating bugs might one day be sprayed on the huge plastic garbage patches in the oceans to clean them up. A type of bacteria evolved to live off plastic in the last few decades.
While the invention of highly durable plastics has had positive impacts for humankind's quality of life, it's that very durability that is causing the plastics pollution problem.
Douglas Kell, a professor of bio-analytical science at Manchester University, said further rounds of work "should be expected to improve the enzyme yet further".
