Building arks for tRNA: Structure and function of the Arc1p family of non-catalytic tRNA-binding proteins
Karanasios, E.; Simos, G. (2010)Following the intricate architecture of the eukaryotic cell, protein synthesis involves formation of many macromolecular assemblies, some of which are composed by tRNA-aminoacylation enzymes. Protein-protein and protein-tRNA ... -
Degradation and Adsorption of Pesticides in Compost-Based Biomixtures as Potential Substrates for Biobeds in Southern Europe
Karanasios, E.; Tsiropoulos, N. G.; Karpouzas, D. G.; Ehaliotis, C. (2010)Biobeds have been used in northern Europe for minimizing point source contamination of water resources by pesticides. However, little is known regarding their use in southern Europe where edaphoclimatic conditions and ... -
Incorporation of the Arc1p tRNA-binding domain to the catalytic core of MetRS can functionally replace the yeast Arc1p-MetRS complex
Karanasios, E.; Boleti, H.; Simos, G. (2008)The catalytic core of methionyl-tRNA synthetase (MetRS) is conserved among all life kingdoms but, depending on species origin, is often linked to noncatalytic domains appended to its N- or C-terminus. These domains usually ... -
Isolation of soil bacteria able to hydrolyze both organophosphate and carbamate pesticides
Chanika, E.; Georgiadou, D.; Soueref, E.; Karas, P.; Karanasios, E.; Tsiropoulos, N. G.; Tzortzakakis, E. A.; Karpouzas, D. G. (2011)Two bacteria identified as Pseudomonas putida and Acinetobacter rhizosphaerae able to rapidly degrade the organophosphate (OP) fenamiphos (FEN) were isolated. Denaturating gradient gel electrophoresis analysis revealed ... -
Key parameters and practices controlling pesticide degradation efficiency of biobed substrates
Karanasios, E.; Karpouzas, D. G.; Tsiropoulos, N. G. (2012)We studied the contribution of each of the components of a compost-based biomixture (BX), commonly used in Europe, on pesticide degradation. The impact of other key parameters including pesticide dose, temperature and ... -
Molecular determinants of the yeast Arc1p - Aminoacyl-tRNA synthetase complex assembly
Karanasios, E.; Simader, H.; Panayotou, G.; Suck, D.; Simos, G. (2007)Eukaryotic aminoacyl-tRNA synthetases are usually organized into high-molecular-weight complexes, the structure and function of which are poorly understood. We have previously described a yeast complex containing two ... -
Novel biomixtures based on local Mediterranean lignocellulosic materials: Evaluation for use in biobed systems
Karanasios, E.; Tsiropoulos, N. G.; Karpouzas, D. G.; Menkissoglu-Spiroudi, U. (2010)The composition of biomixtures strongly affect the efficacy of biobeds. Typically, biomixture consists of peat (or compost), straw (SIR) and topsoil (1:2:1 by volume). Straw guarantees a continuous supply of nutrients and ... -
On-farm biopurification systems for the depuration of pesticide wastewaters: recent biotechnological advances and future perspectives
Karanasios, E.; Tsiropoulos, N. G.; Karpouzas, D. G. (2012)Point source contamination of natural water resources by pesticides constitutes a serious problem and on-farm biopurification systems (BPS) were introduced to resolve it. This paper reviews the processes and parameters ... -
Optimization of Biomixture Composition and Water Management for Maximum Pesticide Dissipation in Peat-Free Biobeds
Karanasios, E.; Papadi-Psyllou, A.; Karpouzas, D. G.; Tsiropoulos, N. G. (2012)Biomixture composition and water management are key factors controlling biobeds performance. Although compost-biomixtures (BXs) possess high degradation efficiency, their low water-holding capacity compared with peat-biomixtures ...
