Snake venom thrombin-like enzymes: from reptilase to now

Abstract: The snake venom thrombin-like enzymes (SVTLEs) comprise a number of serine proteases functionally and structurally related to thrombin. Until recently, only nine complete sequences of this subgroup of the serine protease family were known. Over the past 5 years, the primary structure of several SVTLEs has been characterized, and now this family includes several members. Of particular interest is their possible use in pathologies such as thrombosis. The aim of the present review is to summarize the state of the… Show more

“…Thrombin-like enzymes are medically promising and act as defibrinogenating agents, such as ancrod and batroxobin, that have been extensively used in victims of thrombosis, myocardial infarction, peripheral vascular disease, acute ischemia and renal transplant rejection (15). Additionally, these enzymes are employed in deep corneal ulcer repair and non-pregnant canine uterus (16,17).…”

“…Os sítios de glicosilação podem estar presentes nas SVSPs em posições não homólogas, sendo I n t r o d u ç ã o | 13 que a importância do conteúdo de carboidratos na relação estrutura-função destas moléculas não foi, até o momento, determinada (CASTRO et al, 2004;SAJEVIC et al, 2011 Diversos animais peçonhentos e venenosos produzem toxinas que têm como alvo fatores do sistema hemostático. As peçonhas de serpentes apresentam uma variedade de proteínas e peptídeos, como fosfolipases A 2 , metaloproteases, L-aminoácido oxidases, serinoproteases, lectinas tipo-C, 5'-nucleotidases e desintegrinas, que agem sobre pontos específicos do sistema sanguíneo, resultando em distúrbios hemostáticos que facilitam a captura da presa.…”

“…Adicionalmente, muitas enzimas trombina-simile podem induzir a agregação plaquetária por ativarem os receptores para fator de von Willebrand e fibrinogênio (GPIb e GPIIb-IIIa, respectivamente), ou por clivarem os receptores ativados por proteinase (PAR) 1 e 4 (SERRANO & MAROUN, 2005;SAJEVIC et al, 2011). Assim, essas toxinas podem representar importantes ferramentas no estudo dos mecanismos fisiológicos envolvidos na ativação e agregação de plaquetas (CASTRO et al, 2004;MACKESSY, 2010).…”
