Description
Sanae Hori and Fumiyoshi Okazaki report a 2024 study of an enzyme from a human gut germ that cuts a seaweed sugar. The sugar, beta-1,3-xylan, fills the walls of red and green algae. All cutters known before came from marine germs, so a gut source opens a new front.
The team built the gut enzyme in a lab host germ and purified it in two steps. The enzyme cut only its target sugar and freed short sugar chains, with a two unit chain as the main product. Its best heat sat at 50 degrees, above the marine enzymes. The result hints that gut Bacteroides germs hold an unknown system to use this seaweed sugar.
