What is an Investigation?Filters
Objectives: Empowering smooth implementation and fruitful completion of all WPs and tasks. Implementation of a data management plan for efficient dissemination under F.A.I.R. principles.
Description of Work: The PI of the project with the heads of the collaborating groups will closely monitor the progress of the technical and administrative tasks and it will implement actions to correct any deviation from the established work-plan. The whole group will meet regularly every six months or more ...
Objectives: Establishment of the chemoenzymatic process with the best GO-ATA hybrid catalysts. Highlighting of the potential of the process in semi-preparative scale.
Description of Work: The best hybrid catalysts identified in WP3 will be investigated in coupled one-pot reactions selected in WP1, in batch and continuous flow reactors. The productivity of the system will be optimized with response surface methodology (RSM), for parameters such as temperature, duration, substrate concentration ...
Objectives: Development of efficient ATA immobilization approach. Production of a hybrid catalyst of high catalytic efficiency.
Description of Work: Τhe ATAs selected in WP2 will be expressed, purified and covalently and/or non-covalently immobilized on the GO selected in WP1. The catalytic behavior (in terms of catalytic activity, stability and reusability) and the structural implications of the immobilization will be investigated. For comparison purposes, the non-optimized ATAs (prior to the ...
Objectives: Identification of amine transaminases (ATAs) able to catalyze efficiently the amination of a desired set of ketones and aldehydes (expected products of GO oxidation). Optimization of the most potent biocatalysts, in terms of catalytic efficiency, stability, availability of functional groups for covalent immobilization.
Description of Work: ATAs from our construct selection (>30 wild-type and variants of both (R)- and (S)-enantioselectivity) with different substrate selectivity will ...
Objectives: Protocol identification and establishment for the synthesis of high-performing catalytic GO in the desired oxidation reactions under mild conditions. Characterization of the most prominent materials synthesized and comparison to commercially available material.
Description of Work: Several established chemical methods will be used for the synthesis of GO. Each batch will be characterized, for instance for its C/O ratio, surface area and conductivity. The catalytic profile of the ...
