Critical roles of soluble starch synthase SSIIIa and granule-bound starch synthase Waxy in synthesizing resistant starch in rice.
Changes in human lifestyle and food consumption have resulted in a large increase in the incidence of type-2 diabetes, obesity, and colon disease, especially in Asia. These conditions are a growing threat to human health, but consumption of foods high in resistant starch (RS) can potentially reduce their incidence. Strategies to increase RS in rice are limited by a lack of knowledge of its mole...
متن کاملSolubilization of the starch-granule-bound starch synthase of normal maize kernels.
The starch-granule-bound starch synthase from Zea mays has been solubilized with a recovery of between 50 and 84%. Chromatography of the solubilized enzyme on DEAE-Sepharose resolves two fractions of activity which may be distinguished by their response to citrate. Neither solubilized isoenzyme displays any significant activity with UDPglucose.
متن کاملBlue maize: morphology and starch synthase characterization of starch granule.
The use of pigmented maize varieties has increased due to their high anthocyanins content, but very few studies are reported about the starch properties of these grains. The aim of this work was to isolate the starch granules from pigmented blue maize and carry out the morphological, physicochemical, and biochemical characterization studies. The proximate composition of starch granules showed h...
متن کاملGranule-bound starch synthase: structure, function, and phylogenetic utility.
Interest in the use of low-copy nuclear genes for phylogenetic analyses of plants has grown rapidly, because highly repetitive genes such as those commonly used are limited in number. Furthermore, because low-copy genes are subject to different evolutionary processes than are plastid genes or highly repetitive nuclear markers, they provide a valuable source of independent phylogenetic evidence....
متن کاملInteraction with amylopectin influences the ability of granule-bound starch synthase I to elongate malto-oligosaccharides.
This paper examines the properties in soluble form of two isoforms of starch synthase. One of these, granule-bound starch synthase I (GBSSI), is responsible for the synthesis of amylose inside the amylopectin matrix of the starch granule in vivo. The other, starch synthase II (SSII), is involved in amylopectin synthesis. Both isoforms can use amylopectin and malto-oligosaccharide as substrates ...
