Starch synthase and starch branching enzyme from germinating castor bean endosperm

Phytochemistry, 1989
Abstract Sucrose, but not starch, accumulates to high levels during fat utilization in young castor bean seedlings. High activities of starch synthase, starch branching enzyme and starch phosphorylase were present in the tissue but the very low ADPG pyrophosphorylase activity probably accounts for the low level of starch accumulation.

Wheat genome specific granule-bound starch synthase I differentially influence grain starch synthesis

Carbohydrate Polymers, 2014
Wheat grain development is a complex process and is characterized by changes in physicochemical and structural properties of starch. The present study deals with endosperm starch physicochemical properties and structure during development in different granule-bound starch synthase I (GBSSI) null also known as waxy (Wx) genotypes.

Branching patterns in leaf starches from Arabidopsis mutants deficient in diverse starch synthases

Carbohydrate Research, 2015
This is the first report on the cluster structure of transitory starch from Arabidopsis leaves. In addition to wild type, the molecular structures of leaf starch from mutants deficient in starch synthases (SS) including single enzyme mutants ss1-, ss2-, or ss3-, and also double mutants ss1-ss2- and ss1-ss3- were characterized. The mutations resulted in

Granule‐bound starch synthase I

European Journal of Biochemistry, 2002
Starch defines a semicrystalline polymer made of two different polysaccharide fractions. The A‐ and B‐type crystalline lattices define the distinct structures reported in cereal and tuber starches, respectively. Amylopectin, the major fraction of starch, is thought to be chiefly responsible for this semicrystalline organization while amylose is ...

Single-nucleotide polymorphisms in rice starch synthase IIa that alter starch gelatinisation and starch association of the enzyme

Functional Plant Biology, 2005
The starch synthase IIa (SSIIa) gene of rice (Oryza sativa L.) has been shown to be the alk gene that controls alkali disintegration of rice grains, although the effects of naturally occurring alk mutant alleles on enzyme function have yet to be determined.

Distribution of Branches in Whole Starches from Maize Mutants Deficient in Starch Synthase III

Journal of Agricultural and Food Chemistry, 2014
An earlier study explored the possibility of analyzing the distribution of branches directly in native, whole starch without isolating the amylopectin component. The aim of this study was to explore if this approach can be extended to include starch mutants.

Resistant starch and starch pasting properties of a starch synthase IIa-deficient wheat with apparent high amylose

Australian Journal of Agricultural Research, 2006
The bread wheat (Triticum aestivum L.) analysed in this study has been produced by genetically eliminating the starch synthase IIa and shows apparent high amylose (HA) in the flour starch. Some starch properties of the HA wheat were analysed. The HA wheat contained 2.8–3.6% resistant starch (RS), much more than the normal (control) wheat, which ...

Starch Breakdown during Banana Ripening: Sucrose Synthase and Sucrose Phosphate Synthase

Journal of Agricultural and Food Chemistry, 1995
Starch contents, respiration rates, sucrose synthase (SS) activity, and sucrose phosphate synthase (SPS) activity in crude extract or in partially purified preparations were comparatively studied during fruit development and ripening in either attached or detached bananas.

Soluble starch synthases and starch branching enzymes from developing seeds of sorghum

Phytochemistry, 1985
Abstract Soluble starch synthases and branching enzymes have been partially purified from developing sorghum seeds. Two major fractions and one minor fraction of starch synthase were eluted on DEAE-cellulose chromatography. The minor enzyme eluted first and was similar to the early eluting major synthase in citrate-stimulated activity, faster ...
