Cloning, expression and biochemical characterization of xanthine and adenine phosphoribosyltransferases from thermus thermophilus Hb8
(Biocatalysis And Biotransformation, 2018)
Enhancement of Photophysical and Photosensitizing properties of Flavin Adenine Dinucleotide by Mutagenesis of the C-terminal extension of a bacterial Flavodoxin Reductase
(Wiley Vch Verlag, 2015-03)
The role of the mobile C-terminal extension present in Rhodobacter capsulatus ferredoxin–NADP(H) reductase (RcFPR) was evaluated using steady-state and dynamic spectroscopies for both intrinsic Trp and FAD in a series of ...
Label-free electrochemical aptasensor for the detection of lysozyme
(Elsevier Science, 2009-04)
This work reports the advantages of a label free electrochemical aptasensor for the detection of lysozyme. The biorecognition platform was obtained by the adsorption of the aptamer on the surface of a carbon paste electrode ...
Metabolic shift in the production of corrinoid compounds by Lactobacillus coryniformis in the absence of purines
(Elsevier France-editions Scientifiques Medicales Elsevier, 2020-01)
Lactobacillus coryniformis CRL 1001 and L. reuteri CRL 1098 have the complete genes necessary to synthesize pseudo-cobalamin as final product in a vitamin B12 free commercial medium. Unlike vitaminB12 (the most biologically ...
Trypanocidal properties, structure-activity relationship and computational studies of quinoxaline 1,4-di-N-oxide derivatives
(Elsevier, 2011)
Pyrazole and propenone quinoxaline derivatives were tested against intracellular forms of Leishmania peruviana and Trypanosoma cruzi. Both series were tested for toxicity against proliferative and non-proliferative cells. ...
Intermolecular magnetic interactions in stacked DNA base pairs
(Royal Society of Chemistry, 2017-10)
The influence of pi-stacking on the magnetic properties of atoms that belong to adenine-thymine and guanine-cytosine pairs in sequences of three and five layers of DNA base pairs was analysed. As probes we used NMR ...
Colloidal gold clusters formation and chemometrics for direct SERS determination of bioanalytes in complex media
(Pergamon-Elsevier Science Ltd, 2020-01)
In this work, we report the sensitive and selective sensing of the purine bases adenine and guanine in urine matrix by using surface-enhanced Raman spectroscopy (SERS) and a colloidal SERS substrate. To identify suitable ...
