The effects of the C-terminal amidation of mastoparans on their biological actions and interactions with membrane-mimetic systems
(Biochimica Et Biophysica Acta-biomembranes, 2014-10-01) [Artigo]
Polycationic peptides may present their C-termini in either amidated or acidic form; however, the effects of these conformations on the mechanisms of interaction with the membranes in general were not properly investigated ...
Influence of the environmental heterogeneity of breeding ponds on anuran assemblages from southeastern Brazil
(Canadian Journal of Zoology-revue Canadienne de Zoologie, 2009-08-01) [Artigo]
We hypothesized that the environmental heterogeneity of breeding ponds influences the species composition and species richness of anuran assemblages from southeastern Brazil, because it provides humidity, shelter, and ...
Protonectin (1-6): A novel chemotactic peptide from the venom of the social wasp Agelaia pallipes pallipes
(Toxicon, 2010-11-01) [Artigo]
Peptides constitute the largest group of Hymenoptera venom toxins; some of them interact with GPCR, being involved with the activation of different types of leukocytes, smooth muscle contraction and neurotoxicity. Most of ...
Cardiorespiratory responses to hypoxia in the African catfish, Clarias gariepinus (Burchell 1822), an air-breathing fish
(Journal of Comparative Physiology B: Biochemical Systemic and Environmental Physiology, 2011-10-01) [Artigo]
The African catfish, Clarias gariepinus, possesses a pair of suprabranchial chambers located in the dorsal-posterior part of the branchial cavity having extensions from the upper parts of the second and fourth gill arches, ...
Penicillium expansum versus antagonist yeasts and patulin degradation in vitro
(Brazilian Archives of Biology and Technology, 2007-07-01) [Artigo]
Considerando o antagonismo e degradação de patulina detectados em Pichia membranifaciens e Sporobolomyces roseus no estudo preliminar, este trabalho avaliou o efeito antagônico de Pichia ohmeri 158 no desenvolvimento de ...
Three exopolysaccharides of the beta-(1 -> 6)-D-glucan type and a beta-(1 -> 3;1 -> 6)-D-glucan produced by strains of Botryosphaeria rhodina isolated from rotting tropical fruit
(Carbohydrate Research, 2008-09-22) [Artigo]
Four exopolysaccharides (EPS) obtained from Botryosphaeria rhodina strains isolated from rotting tropical fruit (graviola, mango, pinha, and orange) grown on sucrose were purified on Sepharose CL-4B. Total acid hydrolysis ...
Autonomic control of post-air-breathing tachycardia in Clarias gariepinus (Teleostei: Clariidae)
(Journal of Comparative Physiology. B, Biochemical, Systemic, and Environmental Physiology, 2015) [Artigo]
The African catfish (Clarias gariepinus) is a teleost with bimodal respiration that utilizes a paired suprabranchial chamber located in the gill cavity as an air-breathing organ. Like all air-breathing fishes studied to ...
Formation of a ternary complex for selenocysteine biosynthesis in bacteria
(The Journal Of Biological Chemistry, 2015-09-16) [Artigo]
The synthesis of selenocysteine-containing proteins (selenoproteins) involves the interaction of Selenocysteine Synthase (SelA), tRNA (tRNASec), Selenophosphate Synthetase (SelD, SPS), a specific elongation factor (SelB) ...
