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 ...
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, ...
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 ...
PE and PS lipids synergistically enhance membrane poration by a peptide with anticancer properties
(Biophysical Journal, 2015-09-01) [Artigo]
Polybia-MP1 (MP1) is a bioactive host-defense peptide with known anticancer properties. Its activity is attributed to excess serine (phosphatidylserine (PS)) on the outer leaflet of cancer cells. Recently, higher quantities ...
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) ...
Effect of the aspartic acid D2 on the affinity of Polybia-MP1 to anionic lipid vesicles
(European Biophysics Journal With Biophysics Letters, 2014-05-01) [Artigo]
Polybia-MP1 (IDWKKLLDAAKQIL-NH2), a helical peptide extracted from the venom of a Brazilian wasp, has broad-spectrum antimicrobial activities without being hemolytic or cytotoxic. This peptide has also displayed anticancer ...
