The unusual high molecular mass of Bothrops protease A, a trypsin-like serine peptidase from the venom of Bothrops jararaca, is due to its high carbohydrate content

“…The glycosylation of the heavy chain probably endows EfP-b with great stability and a high level of resistance to proteolysis [41]. A similar effect has also been demonstrated in Bothrops protease A, glycosylation of which has a stabilizing effect on the protein conformation [38]. (2) The oligosaccharides affect the regulation of protease function, for instance the Agkistrodon actus serine proteinases-I and -II whose N-linked oligosaccharides collide spatially with some inhibitors and hinder their inhibitory binding [37].…”

“…Recently, several glycosylated serine proteases have been isolated from different species, such as lobster [36], Agkistrodon acutus [37], Bothrops jararaca [38] and gila [39]. The bound carbohydrates have some important effects on the structure and function of proteases: (1) Glycosylation stabilizes the spatial structure of a protease.…”

“…The inspection of the sequences of identified peptides (a total of 331 peptides of which 213 were unique peptides; supplemental Table 3), revealed that some of the peptides were likely cleaved off from proteins at cleavage sites that are compatible with SVMP and SVSP proteolytic specificities (supplemental Table 4) (14,45,(73)(74)(75)(76)(77)(78)(79)(80)(81)(82)(83)(84)(85)(86)(87). Based on the results of 662 cleavage sites, there is observed preference across the P4-P4Ј sites for Tyr, Ser, Pro, and Arg at P1 and for Ala, Gln, Gly, and Val at P1Ј, in decreasing order of frequencies (Fig.…”

“…Considerando a existência de diversos componentes N-glicosilados no veneno de serpentes do gênero Bothrops (Lochnit e Geyer, 1995;Murayama et al, 2003;Silva-Junior et al, 2007;Serrano et al, 1998;Silva et al, 2004;Yamashiro et al, 2014) jararaca mostrou a presença de alguns unigenes associados a vias de glicosilação, e a análise de enriquecimento de genes indicou a importância de genes associados à glicosilação para a biossíntese de veneno (Junqueira-de-Azevedo et al, 2015).…”

“…A N-glicosilação é uma modificação pós-traducional descrita em muitas proteínas de venenos de serpentes (Lochnit e Geyer, 1995;Murayama et al, 2003;Silva-Junior et al, 2007;Serrano et al, 1998;Silva et al, 2004;Yamashiro et al, 2014), e dessa forma a mudança no perfil eletroforético das proteínas do veneno submetidas à N-desglicosilação era esperada. Já a análise da O-desglicosilação dos venenos foi afetada pelo tratamento com a neuraminidase, necessário para propiciar o acesso das enzimas para remoção dos O-glicanos.…”
