PURIFICACIÓN Y ALGUNAS PROPIEDADES BIOQUÍMICAS Y MOLECULARES DE UNA NUEVA FOSFOLIPASA A2 NO MIOTÓXICA DEL VENENO DE LA SERPIENTE Bothrops atrox

Abstract: Las fosfolipasas A2 (PLA2 ) del veneno de las serpientes, son enzimas con una variedad de efectos biológicos, debido a sus diferentes isoformas y algunas pudiendo ser miotoxinas. El objetivo de la investigación fue purificar, caracterizar y evaluar la actividad miotóxica de una isoforma de PLA2 ácida (BaPer-PLA2a). Se purificó por DEAE Sephadex-A50, Sephadex-G75 y un sistema automatizado de presión media-NGC. La BaPer-PLA2a tuvo una actividad específica de 34,1 U/mg y un peso molecular de ~14,5 kDa por PAGE-SD… Show more

“…We amplified cDNA transcripts encoding K49-PLA2s, D49-PLA2s, TLEs, P-I and P-III SVMPs, and DIS. Other works have also amplified cDNA from venoms of the snakes included in this study, which has allowed the molecular characterization of the BaMtx [ 14 ], Barnettobin [ 27 ], Pictobin [ 29 ], Atroxlysin-III [ 25 ], Hyal-Ba [ 30 ], Bpic-LAAO [ 20 ], Pictolysin-III [ 17 ], and BaPer-PLA2 [ 26 ].…”

“…Considering all available data as reference, our laboratory has been successfully characterizing several proteins from Peruvian B. pictus , B. barnetti , and B. atrox venoms at the molecular level, using venom-derived RNA [ 14 , 24 , 25 , 26 , 27 ]. Now, we believe that, in addition to molecular identification, venom-derived RNA has a potential for RNA-based technologies such as cDNA library construction, transcriptomics, gene expression analysis, and recombinant protein synthesis.…”

“…We determined PLA2 activity by measuring the clotting time of a 45% egg yolk emulsion with 10 mM Tris HCl buffer and 10 mM calcium chloride pH 7.4, after incubation with 0.125 mg/mL of L. muta muta venom for 10 min at 37 °C 6 .…”

“…The venom of the snake Lachesis muta muta , which inhabits the Peruvian jungle and is known as “shushupe”, has high PLA2 activity. For this reason, the search for inhibitors of this enzyme is proposed as an alternative to understand the mechanism of the anti-inflammatory process 6 .…”
