Backbone Flexibility Controls the Activity and Specificity of a Protein−Protein Interface: Specificity in Snake Venom Metalloproteases
(2010-07-09)Protein-protein interfaces have crucial functions in many biological processes. The large interaction areas of such interfaces show complex interaction motifs. Even more challenging is the understanding of (multi)specificity ... -
Bacterial communities in residential wastewater treatment plants are physiologically adapted to high concentrations of quaternary ammonium compounds
(2023-08-28)Benzalkonium chloride (BAC) is a quaternary ammonium compound (QAC) widely used as the active ingredient of disinfectants. Its excessive discharge into wastewater is constant and in high concentrations, likely affecting ... -
Bacterial Sphingomyelinases and Phospholipases as Virulence Factors
(2016-06-15)Bacterial sphingomyelinases and phospholipases are a heterogeneous group of esterases which are usually surface associated or secreted by a wide variety of Gram-positive and Gram-negative bacteria. These enzymes hydrolyze ... -
Bacterias multirresistentes a los antibióticos aisladas de niños hospitalizados de "alto riesgo"
(Revista Médica del Hospital Nacioanl de Niños Dr. Carlos Sáenz, 1978)Between January and September, 1977, 43 strains of Klebslella-Enterobac-ter, 17 of Pseudomonas and 6 of Escherlchla coli —all resistant to several drugs—were isolated from 66 children hospitalized in the National Children's ... -
Bactericidal activity of Lys49 and Asp49 myotoxic phospholipases A2 from Bothrops asper snake venom: synthetic Lys49 myotoxin II-(115-129)-peptide identifies its bactericidal region
(1998)Mammalian group-II phospholipases A2 (PLA2) of inflammatory fluids display bactericidal properties, which are dependent on their enzymatic activity. This study shows that myotoxins II (Lys49) and III (Asp49), two group-II ... -
Bactericidal and anti-endotoxic properties of short cationic peptides derived from a snake venom Lys49 phospholipase A2
(2005)The activities of short synthetic, nonhemolytic peptides derived from the C-terminal region of myotoxin II, a catalytically inactive phospholipase A2 homologue present in the venom of the snake Bothrops asper, have been ... -
Bases moleculares del reconocimiento de antígenos
(1999)Aunque todos los organismos pertenecientes al reino animal poseen una serie de mecanismos inmunitarios que persiguen mantener su integridad y rechazar la invasión de material foráneo, solo los vertebrados cuentan con un ... -
Benchmarking AI-based plasmid annotation tools for antibiotic resistance genes mining from metagenome of the Virilla River, Costa Rica
(2023)Bioinformatics and Artificial Intelligence (AI) stand as rapidly evolving tools that have facilitated the annotation of mobile genetic elements (MGEs), enabling the prediction of health risk factors in polluted environments, ... -
Bioaugmentation of Sewage Sludge with Trametes versicolor in Solid Phase Biopiles Produces Degradation of Pharmaceuticals and Affects Microbial Communities
(2012-10-02)The use of sludge (biosolids) in land application may contribute to the spread of organic micro pollutants as wastewater treatments do not completely remove these compounds. Therefore, the development of alternative strategies ... -
Bioavailability of in-feed tetracyclines is influenced to a greater extent by crude protein rather than calcium
(2014-12)Feed is a common vehicle for tetracycline administration in animal farming. However, veterinarians and farmers often overlook that common feed components, such as proteins and calcium, may interact with these drugs and ... -
Biochemical and biological characterization of Ecuadorian pitviper venoms (genera Bothriechis, Bothriopsis, Bothrops and Lachesis)
(1996-06)The lethality and enzymatic activities of venoms from six Ecuadorian pitvipers (Bothriechis schlegelii, Bothriopsis punctata, Bothriopsis taeniata, Bothrops asper, Bothrops atrox and Lachesis muta) are similar to those of ... -
Biochemical and biological characterization of two serine proteinases from Colombian Crotalus durissus cumanensis snake venom
(2013-03-01)Two clotting serine proteinases, named Cdc SI and Cdc SII, were isolated and characterized for the first time from Colombian Crotalus durissus cumanensis snake venom. The enzymes were purified using two chromatographic ... -
Biochemical and pharmacological similarities between the venoms of newborn Crotalus durissus durissus and adult Crotalus durissus terrificus rattlesnakes
(1991)A comparative study was performed with the venoms of newborn Crotalus durissus durissus, adult Crotalus durissus terrificus and adult Crotalus durissus durissus snakes. Venom of newborn specimens of C.d. durissus is very ... -
Biochemical characterization and pharmacological properties of a phospholipase A2 myotoxin inhibitor from the plasma of the snake Bothrops asper
(1997-09-15)A protein that neutralizes the biological activities of basic phospholipase A2 (PLA2) myotoxin isoforms from the venom of the snake Bothrops asper was isolated from its blood by affinity chromatography with Sepharose-immobilized ... -
