1. A Boophilus microplus vitellin-degrading cysteine endopeptidase
Here we describe the purification and characterization of a vitellin (VT) degrading cysteine endopeptidase (VTDCE) from eggs of the hard tick Boophilus microplus. A homogeneous enzyme preparation was obtained by chromatographic fractionation on ion-exchange and gel filtration columns and an autolysis step. This step consisted of incubation of a semipurified

2. Endocrinologia e controle da vitelogênese em carrapatos = Endocrinology and control of tick vitellogenesis / Endocrinology and control of tick vitellogenesis
Background: Ticks are distributed worldwide, with impacts on human and animal health. The cattle tick Rhipicephalus (Boophilus) microplus is the main parasite that affects livestock in tropical and subtropical regions of the world, causing large economical losses. Tick control methods are based on the application of chemical acaricides, which has resulted in

4. Structural and functional analysis of VT1 and YP170B vitellins from the Rhabditid nematodes Oscheius tipulae and Caenorhabditis elegans. / Estudo das vitelinas VT1 e YP170B dos nematoides rabditídeos Oscheius tipulae e Caenorhabditis elegans: aspectos estruturais e funcionais.
The N-terminal region of OTI-VIT-1 was expressed and the recombinant polypeptides were purified. OTI-VIT-1 may be homologous to the vitellin YP170B from C. elegans. We identified an intron in the 5 region and two in 3region from Oti-vit-1. Monospecific antisera to PVIT1HisC confirmed that the gene Oti-vit-1 encodes VT1. The recombinant polypeptide P40-H, cor

5. Caracterização da Tick Heme-binding Aspartic Protease (THAP) na embriogênese do carrapato Rhipicephalus (Boophilus) microplus : análise da expressão e da atividade de degradação de vitelina
O carrapato Rhipicephalus (Boophilus) microplus é responsável por perdas econômicas substanciais na bovinocultura, acarretando o uso intensivo de acaricidas. Problemas com os resíduos químicos presentes na carne e no leite, o custo dos acaricidas e a seleção de populações de carrapato resistentes, têm estimulado o desenvolvimento de métodos de con
