Sucrose phosphate synthase and other sucrose metabolizing enzymes in fruits of various species

Abstract: 1991. Sucrose phosphate synthase and other sucrose metabolizing enzymes in fruits of various species Recent reports have suggested that sucrose phosphate synthase (EC 2.4.1.14), a key enzyme in sucrose biosynthesis in photosynthetic "source" tissues, may also be important in some sucrose accumulating "sink" tissues. These experiments were conducted to determine if sucrose phosphate synthase is involved in sucrose accumulation in fruits of several species. Peach (Prunus persica NCT 516) and strawberry (Fragari… Show more

“…The reduction in fruit water content and conversion of cell wall components such as starch, protein, pectin and hemicelluloses into simple soluble sugars during storage are responsible for the increase in TSS content. Furthermore, increase in soluble solids and soluble sugar during the period of fruit ripening may be due to the activity of sucrose-phosphate synthase enzyme (SPS), which is an important enzyme in the biosynthesis of sugars (Hubbard et al, 1991).…”

“…A frutose foi a hexose predominante na manga madura, variando de 2,3 a 3,1%, enquanto a glicose variou de 0,05 a 0,6% (Tabela 1). A razão frutose/glicose (Tabela 1) variou de 4,7 a 48 vezes, confirmando os resultados da literatura [2, 8,10]. Esta relação costuma ser equimolar em frutos como a banana [14], a uva [5] e o mamão [7], como conseqüência, provavelmente, da hidrólise da sacarose pelas invertases.…”

“…Durante o amadurecimento da manga, o conteú-do de ácidos orgânicos diminui e o de açúcares solú-veis aumenta, resultando num predomínio do sabor doce na fruta madura [12]. Parte da escassa literatura disponível, descreve o amido como sendo a principal reserva de carbono utilizada na síntese pós-colheita da sacarose, açúcar predominante na manga madura [6,11,17,18] [8, 9]. Em resumo, existem evidên-cias de que o amadurecimento e o acúmulo dos açúca-res solúveis na manga é iniciado antes da colheita e, embora os teores de amido a esta época possam ser considerados insuficientes, uma parte substancial dos açúcares que concorrem para o adoçamento do fruto maduro é acumulada após a colheita.…”
