H2020 Projects - Industrial Enzymes

Since our very first trip into the realm of EU projects with the KINOMED project, by now we have engaged in 7 different EU projects. The KINOMED project (2010-2013, funded by the Eurostars program) was focused on cloning, expression, purification and fragment-based screening of two kinases, PIM1 and CK2, followed by co-crystallization of the proteins with best fragments found during the screening. The second project was TAKTIC (Translational Kinase Tumour Inhibitor discovery Consortium). The project was focused on the NF-κB signalling pathway, which is activated by cellular responses to stimuli such as stress, cytokines, free radicals, ultraviolet irradiation, etc. The focus of the project was the design of novel inhibitors of NIK, a MAP3K- kinase responsible for the phosphorylation of IKKα homodimers within the so-called non-canonical NF-κB pathway (see for example the NF-κB inhibitors site).

Our current EU project involvements includes: Virus-X, BIOCASCADES, SAFER and PhD4GlycoDrug. All these projects are currently making considerable contribution to expanding our research and business networks, introducing us to new fields and opening up new opportunities.

The Virus-X project targets selected microbial ecosystems to find and analyse new virus genomes and identify new gene products useful for biotechnological applications. A large number of academic and industrial partners (Matis, Bio-Prodict BV, ArcticZymes, SARomics Biostructures, A&A Biotechnology, Pasteur Institute, University of Bergen, Bielefeld University, Blaise-Pascal University, Max Plank Institute, University of Gdansk, Durham University, University of Stuttgart, Lund University) are involved in various aspects of the project. These include environmental sampling and metagenome sequencing; annotation & Structure-Function characterization using bioinformatics tools; cloning, expression & purification of chosen proteins; activity screening; crystallization and X-ray structure determination. By contributing to the structural characterization of the identified proteins, SARomics Biostructures contributes to several of the project’s main scientific objectives, among which are:

• Elucidating the function of hypothetical genes and orphan gene products

• Discovering novel genes and viral enzymes for specific applications

• In-depth studies on the structure-function relationships of the viral enzymes

The virosphere represents the largest reservoir of unknown genetic diversity, while the viral gene pool has enormous potential as a source of new innovative tools for biotechnological applications. Due to their unusual biology and lifecycle, viruses have evolved specialized replication machinery and carry enzymes with unique properties, often very different from cellular host enzymes. Many major milestones of modern biotechnology and molecular biology were achieved using phage gene products, among which is a large number of nucleic acid processing enzymes. Further progress in molecular biotechnology will lead to increasing demands for the discovery and development of new enzymes with new superior properties, most probably from novel organisms. The goal of the Virus-X project is to analyze and exploit the viromes-specific extreme natural environments, in particular geothermal habitats, with the ultimate goal of developing new gene products of high innovation value for applications in biotechnology, pharmaceutical, medicinal and other life science sectors. For this objective, enzyme discovery and other developments in the Virus-X project will focus on specific non-structural viral proteins such as proteins participating in anti-host defense (polynucleotide kinases and RNA ligases), DNA replication/transcription enzymes, DNA ligases, exo- and endonucleases. A distinctive theme in the project is promotion of the discovery of gene products with new functions (Virus-X). Functional screening and X-ray structure determination is used to gain insight into possible activity and functional role of orphan gene products.

The second project with a focus on industrial enzymes is the BIOCASCADES project (Sustainable and Scalable Biocatalytic Cascade Reactions). The project is focused on the development of sustainable (chemo)enzymatic cascade reactions for the synthesis of optically pure chiral amines and aminoalcohols as pharmaceutical ingredients. It is estimated that currently 40% of all pharmaceuticals contain a chiral amine component in their structure. The consortium is formed by eight academic laboratories with complementary expertise – biocatalysis (TU Delft, KTH Stockholm), enzyme discovery (University Greifswald, University Amsterdam), protein engineering (TU Graz, Ruhr-University Bochum) and chemoenzymatic synthesis (University Bielefeld, University Oviedo). They work together with DSM (currently INNOSYN, a spin off from DSM), and four other enterprises with expertise in bioinformatics and structural biology (SARomics Biostructures), enzyme immobilization (Viazym), enzyme production (Enzymicals) and technical-scale biocatalysis (EntreChem).

Cascades reactions (presence of all reagents and catalysts from the beginning) and one-pot reactions (reaction in one compartment with successive addition of catalysts/reagents) from a Green Chemistry point of view represent a very promising approach to performing multi-step syntheses, particularly due to the avoidance of intermediate downstream purification steps. This also significantly contributes to cutting production costs on industrial scale by allowing the utilization of a side product as co-substrate for subsequent reaction steps. Multi-step cascades that use targeted design of cascade reactions, can allow the assembly of enzymatic and chemical steps in a completely novel way, mimicking biological reaction pathways. Among the specific aims of the BIOCASCADES project is to

- combine different well established enzymes and chemical catalysts in an innovative way to design novel cascades

- broaden the catalytic scope by combining enzymatic transformations with transition-metal organic catalysts

- use compartmentalization techniques and enzyme engineering to improve catalyst compatibility and suppress cross reactivity

- optimize space-time yield and atom economy, by establishing novel methods for the shift of equilibrium, in situ (co)-product removal, and by protein engineering

- to develop strategies for the scale-up of viable (chemo)enzymatic cascade reactions

SARomics Biostructures will contribute to the design and production of new stable enzyme variants suitable for cascade reactions in organic or biphasic media by protein engineering, bioinformatic analyses, predictive enzyme design, all assisted by 3D X-ray structure determination. Several exciting publications are on the way from this project and we will do our best to spread a word when they are out!
