Researchers cloned, expressed, and studied an enzyme called α-glucuronidase from a heat-loving microorganism. This enzyme helps convert plant material into sugars needed for biofuels. The α-glucuronidase works best at high temperatures and slightly basic pH levels. It showed good activity on certain types of sugars found in plants. When combined with other enzymes, it improved the conversion of plant material into sugars, which is crucial for biofuels production. This enzyme could be a valuable addition to enzyme mixtures used in biofuels production.
