The research involved approximately 18 collaborators from the LNBR (Brazilian Biorenewables National Laboratory) and the LNLS (Brazilian Synchrotron Light Laboratory), both part of CNPEM, in addition to external researchers from Unicamp and universities in Spain and Canada.<\/p>\n<div id=\"attachment_64717\" style=\"width: 510px\" class=\"wp-caption aligncenter\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-64717\" class=\"size-medium wp-image-64717\" src=\"https:\/\/i0.wp.com\/cnpem.br\/wp-content\/uploads\/2026\/04\/untitled6.jpg?resize=500%2C281&#038;ssl=1\" alt=\"\" width=\"500\" height=\"281\" srcset=\"https:\/\/i0.wp.com\/cnpem.br\/wp-content\/uploads\/2026\/04\/untitled6.jpg?resize=500%2C281&amp;ssl=1 500w, https:\/\/i0.wp.com\/cnpem.br\/wp-content\/uploads\/2026\/04\/untitled6.jpg?resize=768%2C432&amp;ssl=1 768w, https:\/\/i0.wp.com\/cnpem.br\/wp-content\/uploads\/2026\/04\/untitled6.jpg?w=800&amp;ssl=1 800w\" sizes=\"auto, (max-width: 500px) 100vw, 500px\" \/><p id=\"caption-attachment-64717\" class=\"wp-caption-text\">Representation of the enzyme forming a catalytic tunnel that enables interaction with the beta-glucan chain and its continuous processing.<\/p><\/div>\n<p style=\"text-align: justify;\"><a href=\"https:\/\/www.nature.com\/articles\/s41467-026-71224-2\">Published in the scientific journal <em>Nature Communications<\/em>,<\/a> the work describes, for the first time, a process called processive catalysis applied to the breakdown of these compounds. In this mechanism, the enzyme acts continuously on the same molecular chain, without detaching itself after each stage of the reaction, which makes the process more efficient.<\/p>\n<p style=\"text-align: justify;\">According to researcher Mariana Morais, one of the study coordinators, the work utilized various techniques and equipment at CNPEM, including directed mutagenesis techniques and kinetic analyses. The research also included high-resolution X-ray crystallography experiments conducted at Sirius, CNPEM&#8217;s particle accelerator, as well as computer simulations carried out on the Santos Dumont supercomputer, at the National Laboratory for Scientific Computing (LNCC).<\/p>\n<p style=\"text-align: justify;\">\u201cThis integration allowed for the observation, at the atomic level, of all stages of the enzymatic process, from substrate recognition to product release and the restart of the catalytic cycle\u201d, says Morais.<\/p>\n<h3 style=\"text-align: justify;\">\u00a0<strong>Frontiers of bioenergy<\/strong><\/h3>\n<p style=\"text-align: justify;\">According to the researchers, a detailed understanding of this mechanism can guide the development of more efficient processes for utilizing biomass, contributing to a more sustainable economy based on renewable resources.<\/p>\n<p style=\"text-align: justify;\">Beta-(1,3)-glucans are important components of biomass and have the potential to be converted into biofuels and high-value chemicals. Understanding how these molecules are degraded is essential for developing more efficient and sustainable technologies.<\/p>\n<p style=\"text-align: justify;\">The research revealed that the studied enzyme forms a kind of &#8220;molecular tunnel&#8221; when it binds to the substrate, allowing the reaction to occur in a continuous and organized manner. This behavior differs from the mechanisms traditionally known for this type of carbohydrate, which involve discontinuous processes.<\/p>\n<p style=\"text-align: justify;\">According to the authors, this discovery establishes a new paradigm: processive catalysis may be a more common strategy than previously thought among enzymes that act on different types of carbohydrates (or biomolecules).<\/p>\n<p style=\"text-align: justify;\">These compounds also have relevant immunological properties, which expands the potential application of the discovery to the pharmaceutical and nutritional fields.<\/p>\n<div style=\"text-align:justify; margin-top:20px;\"><h2>About CNPEM<\/h2><p>The Brazilian Center for Research in Energy and Materials (CNPEM) is home to a state-of-the-art, multi-user and multidisciplinary scientific environment and works on different fronts within the Brazilian National System for Science, Technology and Innovation. A social organization overseen by the Ministry of Science, Technology and Innovation (MCTI), with the involvement of the Ministry of Education and the Ministry of Health, CNPEM is driven by research that impacts the areas of health, energy, renewable materials, and sustainability. It is responsible for Sirius, the largest assembly of scientific equipment constructed in the country, and is currently constructing Project Orion, a laboratory complex for advanced pathogen research. Highly specialized science and engineering teams, sophisticated infrastructure open to the scientific community, strategic lines of investigation, innovative projects involving the productive sector, and training for researchers and students are the pillars of this institution that is unique in Brazil and able to serve as a bridge between knowledge and innovation.
