“…They share a high level of sequence identity [6]. The monomer crystal structures of Cyt1Aa (PDB ID 3RON), Cyt2Aa (PDB ID 1CBY), and Cyt2Ba (PDB ID 2RCI) have been published (Figure 5) [96,97,98]. Structural similarities are observed among these three toxins.…”

“…The crystal structures of these proteins have been identified (PDB 3RON Cyt1Aa, 2RCI Cyt2Ba, 1CBY Cyt2Aa). These proteins are composed of a single α − β domain, where the two outer layers are α-helix hairpins wrapped around a core of β-strands [23] (Figure 30.4). They show structural homology with Volvatoxin A2, a PFT produced by the fungus Volvariella volvacea [24] (Figure 30.4).…”

“…As toxinas Cyt constituem um grupo menor e distinto de proteínas cristalinas que apresentam atividade citolítica contra algumas larvas de dípteros, particularmente mosquitos e moscas pretas (Simuliidae) (Ben-Dov, E., 2014;Bravo, A., Gill, S.S. & Soberon, M., 2007;Butko, P., 2003;Cohen, S. et al, 2011;Soberon, M., Lopez-Diaz, J.A. & Bravo, A., 2013).…”

“…& Bravo, A., 2013;Yu, X. et al, 2012;Zhang, B. et al, 2006). Até o presente, duas estruturas cristalográficas de toxinas Cyt (Cohen, S. et al, 2011;Cohen, S. et al, 2008) foram depositadas no PDB (www.rcsb.org) e o Comitê para Nomenclatura de Toxinas Bt classificam as toxinas Cyt em três categorias primárias: Cyt1, Cyt2 e Cyt3 (Crickmore, N. et al, 2014). Dois mecanismos de ação foram propostos para essas toxinas, onde um sugere a formação de poros e o outro um mecanismo de ação detergente menos específico (Butko, P., 2003;Soberon, M., Lopez-Diaz, J.A.…”
