OxiZymes 2014OxiZymes 2014
The roots of the Oxizymes meetings go back to Cassis, France, where the first meeting, focusing on laccase research, was held in January 2002, gathering a relatively small group of scientists. In the next OxiZymes meetings in Naples and in Oeiras, the scope has been extended from fundamental and applied aspects of laccases to oxidative enzymes in general. Thus OxiZymes has been established as a platform for scientific discussions and exchange for research focusing on oxidoreductases. In Leipzig in 2010 it hosted for the first time the International Symposium of Peroxidases, especially focusing on the most recent scientific progress related to structure, function, production and applications of peroxidases. The main intent was to bring together both meetings that had a lot in common with the ultimate goal to combine research activities on oxidoreductase enzymes and to benefit from expected synergies. The benefit for the research community was evident, therefore also the meeting in Marseille in 2012 continued to host the Peroxidase Symposium. Finally, it was decided to combine both meetings to attract an international scientific community interested in all kinds of research on oxidoreductases.
OxiZymes in Vienna (July 1st-4th, 2014) will therefore cover recent developments on various copper-dependent enzymes, flavoenzymes, heme peroxidases, catalases and related heme-dependent enzymes.

A group of fungi marked the end of the coal age 300 million years agoA group of fungi marked the end of the coal age 300 million years ago
300 million years ago, the Earth suddenly interrupted massive production of coal. This fact determined the end of the Carboniferous, a period of the Paleozoic Era that had started 60 million years before, characterized by the successive formation of large carbon beds arising from accumulation and burial of ancient trees growing up in vast marshy forests.
An international scientific team with participation of the Spanish Research Council (CSIC) has found out that the end of this coal age coincided with the origin of a group of highly specialized fungi. The results, published in the last number of
Science, indicate that these organisms developed a system for the efficient decay of the vast extent of plant biomass that had colonized terrestrial habitats.
“These primitive organisms, basidiomycete type fungi, had developed a mechanism based on enzymes capable of degrading a barrier extremely recalcitrant until that moment: lignin. This polymer, present in wood, provides strength and rigidity to the trees and makes vessels impervious enabling distribution of water and nutrients throughout the plant”, explains one of the authors, CSIC researcher Ángel T. Martínez.
Researchers have made this finding after comparative analysis of 31 fungal genomes. The study has allowed determining the mechanism that was employed by these fungi to degrade lignin. “This process is based in the production of a type of complex proteins named peroxidases, acting in synergy with other oxidative enzymes. We managed to establish the evolutive pathway and chronology of the different types of peroxidases responsible for lignin biodegradation. Moreover, the results have revealed the existence of peroxidases barely known up to date”, says Martínez, working at the Biological Research Centre of CSIC.
Novel biocatalystsThe enzymes found could be used in the future development of new industrial biocatalysts. The new enzymes will be expressed in model microorganisms and further purified, characterized and modified by protein engineering techniques.
“The same biological agents responsible for coal production decrease during the Carboniferous could nowadays allow us developing biotechnology tools aimed to the sustainable production of biofuels and other products from the renewable feedstock provided by plant biomass”, points out CSIC researcher.
These studies will be carried out in the frame of the European Project PEROXICATS (
www.peroxicats.org), coordinated by CSIC with participation of researchers from the Biological Research Centre (CSIC), the Institute of Natural Resources and Agrobiology (CSIC) and the Institute of Catalysis and Petroleochemistry (CSIC), amongst others. The project counts also with collaboration from a German university and two private companies.

Comparative genomics reveals clues about selective lignin biodegradationComparative genomics reveals clues about selective lignin biodegradation
Lignin depolymerization in nature is efficiently carried out by white-rot fungi, a group of basidiomycetes producing wood decay. Genomic (transcriptomic and secretomic) analysis of Ceriporiopsis subvermispora, a fungus producing selective lignin degradation, compared to Phanerochaete chrysosporium, that simultaneously breaks down lignin and cellulose, has revealed important differences among the genes encoding ligninolytic enzymes present in both genomes, sequenced at the Joint Genome Institute (JGI) of the U.S. Department of Energy. CIB researchers Angel T. Martínez, Elena Fernández-Fueyo and Javier Ruiz-Dueñas have participated (the two latter as first authors) in this international study recently published online in the Proceedings of the National Academy of Sciences *. The interest of the U.S. Department of Energy in this type of studies is related to the use of ligninolytic microorganisms and their enzymes in sustainable production of biofuels, chemicals and other products from plant biomass. The research carried out at the CIB is co-funded by the European Union in the frame of the CSIC coordinated PEROXICATS project (www.peroxicats.org) for the development of enzymatic biocatalysts. A press note referring to this study has been released at the JGI website during the Annual Users Meeting, with participation of two of the CIB researchers.

Industrial use of enzymes
Enzymes catalyze a huge amount of chemical reactions in living organisms, which take place under mild conditions compatible with life, and with exquisite substrate specificity, which permits the simultaneous assemblage of the extraordinarily complex catabolic and anabolic routes that characterize life. Nowadays, the availability of
genetic engineering tools permits large-scale production of enzymes and other proteins at low cost by isolating (or synthesizing) the corresponding genes (or cDNA) and introducing them into adequate expression hosts (often filamentous fungi) after their cloning in expression vectors. Simultaneously,
protein engineering using rational and non-rational designs permits to adapt these enzymes to the industrial application conditions, and to increase their expression yields.
This situation represented a real breakthrough for
industrial biotechnology enabling the production of commercial enzymes at very low costs. The enzymatic biocatalysts obtained are often very competitive and more
environmentally-friendly than the corresponding chemical reagents, at the same time that their substrate specificity permits to obtain specific products (including stereo-specific transformations) that are difficult and/or very expensive to obtain by pure chemical synthesis. In addition to their traditional uses, e.g. in the manufacture of some food products and in diverse microbiological transformations (e.g. fermentation processes), the last decades have seen how enzymes entered different
industrial sectors, such as detergents, food and beverages, textiles, pulp and paper, leather and personal care. Moreover, enzymes have recently started to occupy an important position in the fuel markets, and are slowly entering the market of fine chemicals.
