Canatoxin, a toxic protein from jack beans (Canavalia ensiformis), is a variant form of urease (EC 3.5.1.5): biological effects of urease independent of its ureolytic activity

Autor: C, Follmer, G B, Barcellos, R B, Zingali, O L, Machado, E W, Alves, C, Barja-Fidalgo, J A, Guimarães, C R, Carlini

Publikováno v: The Biochemical journal. 360(Pt 1)

Canatoxin is a toxic protein from Canavalia ensiformis seeds, lethal to mice (LD(50)=2 mg/kg) and insects. Further characterization of canatoxin showed that its main native form (184 kDa) is a non-covalently linked dimer of a 95 kDa polypeptide conta

Mechanism of inhibitory action on platelet activation of a phospholipase A2 isolated from Lachesis muta (Bushmaster) snake venom

Autor: A L, Fuly, O L, Machado, E W, Alves, C R, Carlini

Publikováno v: Thrombosis and haemostasis. 78(5)

Crude venom from Lachesis muta exhibited procoagulant, proteolytic and phospholipase A2 activities. A phospholipase A2, denoted LM-PLA2 was purified from L. muta venom to homogeneity, through a combination of chromatographic steps involving gel-filtr

Purification, physicochemical characterization and N-terminal-amino acid sequence of a phospholipase A2 from Bothrops jararaca venom

Autor: O L, Machado, A L, Oliveira-Carvalho, R B, Zingali, C R, Carlini

Publikováno v: Brazilian journal of medical and biological research = Revista brasileira de pesquisas medicas e biologicas. 26(2)

Snake venoms usually contain multiple molecular forms of phospholipase A2 enzymes (phosphatide acyl hydrolase, E.C. 3.1.1.4; PLA2). Phospholipases A2 induce a wide range of pharmacological effects which may depend or not on the hydrolysis of phosphol

An allergenic 2S storage protein from Ricinus communis seeds which is a part of the 2S albumin precursor predicted by c-DNA data

Autor: O L, Machado, J G, Silva Júnior

Publikováno v: Brazilian journal of medical and biological research = Revista brasileira de pesquisas medicas e biologicas. 25(6)

1. A 1.9S albumin having allergenic activity and denoted Ric c III was isolated from an alcohol extract of defatted Ricinus communis seeds, CB-1A, as a homogeneous protein by ion-exchange chromatography on SP-Sephadex, gel filtration on Sephadex G-75

Isolation and partial characterization of antigen 5.1 from the seeds of Ricinus communis, L. (Var. Amarelo de Irece)

Autor: M C, Costa-e-Silva, O L, Machado, J G, Silva-Júnior

Publikováno v: Brazilian journal of medical and biological research = Revista brasileira de pesquisas medicas e biologicas. 24(2)

Antigen 5.1 was isolated from the most acidic fraction of castor bean allergens (CB-1A) by gel filtration on Sephadex G-75 followed by polyacrylamide gel electrophoresis (PAGE) (yield: 6.2 mg antigen 5.1/g CB-1A). This antigen was homogeneous by the

Structural studies on allergen RC-13 from Ricinus communis L.: isolation and characterization of a major glycopeptide

Autor: J G, Silva Júnior, M A, Garcia, O L, Machado, D M, Grassiano, G B, Domont

Publikováno v: Anais da Academia Brasileira de Ciencias. 62(1)

A glycoprotein, RC-13, isolated from Ricinus communis seeds was reduced, S-alkylated and cleaved by trypsin. The tryptic digest was fractionated by ion-exchange chromatography and a glycopeptide was isolated and purified by high-voltage paper electro

Partial characterization of RC-13, a homogeneous fraction isolated from castor bean allergens (CB-1A)

Autor: J G, Silva Júnior, M A, Garcia, O L, Machado, G B, Domont

Publikováno v: Anais da Academia Brasileira de Ciencias. 59(3)

Allergen RC-13's amino acid composition was determined-Lys3, His1, Arg7, Asp6, Thr2, Ser11, Glu29, Pro2, Gly7, Ala4, Cys6, Val5, Met1, Ile3, Leu3, Tyr1; 91 residues. Partial specific volume and minimum molecular weight evaluated from this composition
