Resumo: The enzyme b-glucosidase hydrolyses the isoflavone glucosides developing aglycones, which are compounds with anticancer effects, that are also related with the astringency observed in soybean flavor. Due to the importance of this enzyme, a study was carried out to determine b-glucosidase activity in soybean (Glycine max (L.) Merrill) cultivars with different contents of isoflavone glucosides (enzyme substrate). The enzyme activity was determined in 51 soybean cultivars sowed in Londrina (latitude 23ºS), in Paraná State, Brazil, and in the cultivar IAS 5 from soybean production regions of different Brazilian states. Among the cultivars, a range of variability of 176.1 to 96.3 units of enzyme activity (cultivars IAC-2 and Embrapa 2, respectively) was observed. A significant variability among cultivars could suggest genetic differences. In the states of Rio Grande do Sul, Paraná and Mato Grosso do Sul, the cultivar IAS 5 presented similar average of b-glucosidase activity: 132.1, 131.9 and 132.5 units, respectively. Among locations in the states, the cultivar IAS 5 presented a variability for enzyme activity from 138.8 to 124.8 units, which were statistically different. In spite of statistics, the numerical values were not too different to assume that environmental conditions affected enzyme activity. A non-significative correlation for isoflavone glucoside concentrations and enzyme activity was observed among cultivars.

Pela importância dessa enzima, conduziu-se um estudo para determinar a atividade da b-glicosidase em cultivares de soja (Glycine max (L.) Merrill) com teores diferenciados de isoflavonóides glicosídeos (substratos da enzima). A atividade enzimática foi determinada em 51 cultivares de soja semeadas em Londrina, latitude 23ºS, no Estado do Paraná, e na cultivar IAS 5, proveniente de regiões produtoras de soja de diferentes estados do Brasil. Entre as cultivares observou-se uma amplitude na variabilidade de 176,1 a 96,3 unidades de atividade enzimática nas cultivares IAC-2 e Embrapa 2, respectivamente. Entretanto, a variabilidade significativa observada entre as cultivares pode estar indicando diferenças genéticas. Nos estados do Rio Grande do Sul, Paraná e Mato Grosso do Sul, a cultivar IAS 5 apresentou atividades similares com valores médios de b-glicosidase iguais a 132,1, 131,9 e 132,5 unidades, respectivamente. Entre os locais nos estados, a cultivar IAS 5 apresentou variabilidade na atividade da enzima de 138,8 a 124,8 unidades, as quais foram estatisticamente diferentes. No entanto, apesar da estatística, os valores numéricos não foram tão diferentes para assumir que houve influência do ambiente sobre a atividade da enzima. Entre as cultivares, não houve correlação significativa entre o teor de isoflavonóides glicosídeos e a atividade da enzima.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCarrão-Panizzi, Mercedes ConcórdiaBordingnon, José Renato2000-05-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5871Pesquisa Agropecuaria Brasileira; v.35, n.5, maio 2000; 873-878Pesquisa Agropecuária Brasileira; v.35, n.5, maio 2000; 873-8781678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/5871/2975info:eu-repo/semantics/openAccess2014-08-18T20:06:03Zoai:ojs.seer.sct.embrapa.br:article/5871Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-08-18T20:06:03Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
