Novel enzyme from tiny gribble could prove a boon for biofuels research
Date:6/18/2013

Researchers from the United Kingdom, the Energy Department's National Renewable Energy Laboratory (NREL), and the University of Kentucky have recently published a paper describing a novel cellulose-degrading enzyme from a marine wood borer Limnoria quadripunctata, commonly known as the gribble.

Gribbles are biologically intriguing because they exhibit a relatively unique ability to produce their own enzymes instead of using symbiotic microbes to break down the biomass they eat. New biomass-degrading enzymes from novel sources such as the gribble may prove beneficial to the biofuels industry.

Gribbles are 1-3 millimeters in length, but collectively they bore through wood quickly, and are responsible for significant natural and man-made marine timber damage around the world. Scientists at Universities of Portsmouth and York in the United Kingdom and the University of Kentucky in the United States, with researchers from NREL, are hoping to turn that special talent into a source of novel enzymes for the biofuels industry.

A paper describing the crystal structure of a key enzyme produced by the gribble appears online in Proceedings of the National Academy of Sciences of the United States of America. http://www.pnas.org/content/early/2013/05/31/1301502110.short

Gribbles live in inter-tidal zones and, similar to termites, they burrow into wood. Gribbles, unlike termites or many other animals including people, do not rely on gut bacteria to make enzymes to aid their digestion. Gribbles instead exhibit a sterile gut, and secrete their own enzymes into their guts made in a special organ termed the heptopancreas that runs the entire length of their body.

Interestingly, several of the enzymes produced by gribbles are in the same important enzyme classes that are typically harvested from fungi in the biosphere for industrial
