Isolation and partial characterization of a lectin from Bauhinia pentandra (bong) vog. Ex. Steua.

Abstract: Bauhinia pentandra (Bong) Vog. ex. Steua seeds were investigated with respect to phenologic aspects (size, mass, hilum and length) and with respect to their chemical composition. The total nitrogen content of the seed flour was determined, and the flour was extracted in different pH values. A lectin was isolated from the seeds by Sepharose-4B affinity chromatography. The homogeneity of the lectin was demonstrated by SDS-PAGE in the presence of beta-mercaptoethanol. Only one protein band with an apparent molecu… Show more

“…Here, we report the fi rst primary structure determination of a Caesalpinoideae lectin isolated from crude extracts of B. variegata seeds, obtained at different pH values (2.6, 7.6 and 9.0). The crude extracts strongly agglutinated native rabbit and human red blood cells ( The more specifi c haemagglutinating activity observed with extracts obtained at pH 2.6 was similar to the activity observed with extracts from B. pentandra (Silva et al 2001).…”

“…Based on these studies new lectins from different species of the Bauhinia genus have been recently identifi ed. These include the lectin from B. monandra (BmoLL) which has insecticidal activity (Macedo et al 2007) and the lectins from B. pentandra (Silva et al 2001) and B. variegata var. candida (Silva et al 2007).…”

“…Em experimentos de caracterização da AHE é comum ocorrer diferenças de hemaglutinação em eritrócitos distintos, como demonstra Silva et al (2001a), ao estudar a especificidade de hemaglutinação, de frações purificadas de Bauhinia pentandra sobre eritrócitos de coelho, frango, pombo e de grupos sanguíneos humanos pertencentes ao sistema ABO, onde constatou forte hemaglutinação em eritrócitos de coelho e fracamente em eritrócitos do grupo sanguíneo humano tipo A. As frações purificadas de sementes de Canavalia ensiformis e Dioclea grandiflora apresentaram especificidade somente por glóbulos vermelhos humanos (Melgarejo et al, 2005).…”

“…Adicionalmente, estudos têm comprovado que as lectinas isoladas de sementes de leguminosas como Bauhinia pentandra, Crotalaria pallida, Talisia esculenta, Canavalia ensiformis e Dioclea grandiflora, apresentam a prevalência de bandas protéicas com massas moleculares variando de 20-40 kDa (Silva et al, 2001a;Rego et al, 2002;Freire et al, 2002;Melgarejo et al, 2005).…”

“…Observa-se que a maior concentração de proteína foi obtida no pH 8, ao passo que a maior atividade hemaglutinante ocorreu no pH 6. Silva et al (2001) sugerem que se deve escolher o pH em que for detectada a maior atividade hemaglutinante. Optou-se então, por trabalhar em pH 6, priorizando a maior atividade hemaglutinante.…”
