Endocrine disrupting compounds (EDCs) have been studied due to their impact on human health and increasing awareness of their impact on wildlife species. Studies concerning the organ-specific molecular effects of EDC in invertebrates are important to understand the mechanisms of action of this class of toxicants but are scarce in the literature. We have used a dose/response approach to unravel the...<br/><br/>Marco F L Lemos, Ana Cristina Esteves, Bart Samyn, Isaak Timperman, Jozef van Beeumen, António Correia, Cornelis A M van Gestel, Amadeu M V M Soares (2010) <i>Chemosphere</i> <i></i> <i></i> 79: 5 570-576<br/>

The growing interest in the application of proteomic technologies to solve toxicology issues and its relevance in ecotoxicology research has resulted in the emergence of 'ecotoxicoproteomics'. There is a general consensus that ecotoxicoproteomics is a powerful tool to spot early molecular events involved in toxicant responses, which are responsible for the adverse effects observed at higher levels...<br/><br/>Marco F L Lemos, A Soares, A C Correia, Ana C Esteves (2010) <i>Proteomics</i> <i></i> <i></i> 10: 4 873-887<br/>

The antioxidant activity of different edible mushrooms was evaluated considering the different contribution of individual and combined extracts. The radical scavenging capacity was evaluated through hydrogen atom transfer and single electron transfer reaction-based assays: DPPH radical scavenging activity and reducing power, respectively. The inhibition of lipid peroxidation was studied in liposso...<br/><br/>Bruno Queiros, Joao C M Barreira, Ana Cristina Sarmento, Isabel C F R Ferreira (2009) <i>Int J Food Sci Nutr</i> <i></i> <i></i> : 1-13<br/>

Aspartic proteinases (AP) play major roles in physiologic and pathologic scenarios in a wide range of organisms from vertebrates to plants or viruses. The present work deals with the purification and characterisation of four new APs from the cardoon Cynara cardunculus L., bringing the number of APs that have been isolated, purified and biochemically characterised from this organism to nine. This i...<br/><br/>Ana Cristina Sarmento, Henrique Lopes, Cláudia S Oliveira, Rui Vitorino, Bart Samyn, Kjell Sergeant, Griet Debyser, Jozef Van Beeumen, Pedro Domingues, Francisco Amado, Euclides Pires, M Rosário M Domingues, Marlene T Barros (2009) <i>Planta</i> <i></i> <i></i> 230: 2 429-439<br/>

In order to increase understanding of the basis of the stability of the native conformational state of porcine pepsin A, a strategy based on induction and monitoring of protein denaturation was developed. Structural perturbation was achieved by adding acetonitrile (MeCN) to the protein-solvent system. MeCN was found to induce non-coincident disruption of the secondary and tertiary structural featu...<br/><br/>T Cardoso, C Oliveira, A C Sarmento, A Pereira, M A Nutley, T Jess, S M Kelly, A Cooper, N C Price, E Pires, M Barros (2009) <i>Int J Biol Macromol</i> <i></i> <i></i> 45: 3 213-220<br/>

The carbapenem-hydrolyzing B-lactamase SFC-1 from Serratia fonticola UTAD54 was overexpressed in Escherichia coli, purified, and characterized. The enzyme exhibited an apparent molecular mass of 30.5 kDa, determined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. SFC-1 hydrolyzes penicillins, cephalosporins, aztreonam, and carbapenems and is inhibited by clavulanic acid, sulbactam...<br/><br/>F Fonseca, A C Sarmento, I Henriques, B Samyn, J van Beeumen, P Domingues, M R Domingues, M J Saavedra, A Correia (2007) <i>Antimicrob.

The kinetics of the structural changes affecting cardosin A, a plant aspartic proteinase (AP) from Cynara cardunculus L., in the presence of a mixture of acetonitrile (AN) in water (W) was studied. Incubation of cardosin A with 10% (v/v) AN resulted in a gradual increase in protein helicity, accompanied by changes in the tertiary structure, seen by changes in the intrinsic fluorescence of tryptoph...<br/><br/>Anna V Shnyrova, Claudia S Oliveira, Ana C Sarmento, Marlene T Barros, Galina G Zhadan, Manuel G Roig, Valery L Shnyrov (2006) <i>Int J Biol Macromol</i> <i></i> <i></i> 39: 4-5 273-279<br/>

Cardosin A, a plant aspartic proteinase, capable of synthesising peptides, was investigated through synthesis of five methyl esters amino acid substrates as amino donors and nine benzyloxycarbonyl amino acid and peptide carboxyl donors. It was found that cardosin A is able to catalyse the synthesis of several peptide bonds, being the preference order for the carboxyl components the following: CBz....<br/><br/>A C Sarmento, C Oliveira, E Pires, F Amado, M Barros (2004) <i>Journal of Molecular Catalysis B: Enzymatic</i> 28: 33-37<br/>

A Bacillus licheniformis strain, 189, isolated from a hot spring environment in the Azores, Portugal, strongly inhibited growth of Gram-positive bacteria. It produced a peptide antibiotic at 50 degrees C. The antibiotic was purified and biochemically characterized. It was highly resistant to several proteolytic enzymes. Additionally, it retained its antimicrobial activity after incubation at pH va...<br/><br/>Sónia Mendo, Nuno André Faustino, Ana Cristina Sarmento, Francisco Amado, Arthur J G Moir (2004) <i>Biotechnol Lett</i> <i></i> <i></i> 26: 2 115-119<br/>

This investigation showed that cardosin A not only is active in media with organic solvents, cleaving the -chain of oxidised insulin at three susceptible peptide bonds, but also maintains its specificity in all media tested. Additionally, the presence of organic solvents in the reaction media led to modifications of enzyme selectivity, which enabled the detection of intermediate products. While so...<br/><br/>A Cristina Sarmento, CS Oliveira, E M Pires, P J Halling, M T Barros (2004) <i>Journal of Molecular Catalysis B: Enzymatic</i> 31: 137-141<br/>
