Starch synthases and starch branching enzymes from Pisum sativum

Phytochemistry, 1981
Abstract Concentrations of ADPglucose:α-1,4-glucan-4-glucosyltransferase (starch synthase) and α-1,4 glucan: α-1,4-glucan-6-glycosyltransferase (branching enzyme) from developing seeds of Pisum sativum were measured. Primed starch synthase activity increased from 8 to 14 days after anthesis and decreased by 50 % at 26 days.

Specificity of starch synthase isoforms from potato

European Journal of Biochemistry, 1999
In higher plants several isoforms of starch synthase contribute to the extension of glucan chains in the synthesis of starch. Different isoforms are responsible for the synthesis of essentially linear amylose chains and branched, amylopectin chains.

In vitro studies of enzymatic properties of starch synthases and interactions between starch synthase I and starch branching enzymes from rice

Plant Science, 2014
The present study was conducted to characterize the functions of the major starch synthase (SS) isozymes SSI, SSIIa, and SSIIIa in rice endosperm and their functional interaction with starch branching enzyme (BE), by using their purified recombinant proteins.

Maize leaf and kernel starch synthases and starch branching enzymes

Phytochemistry, 1988
Abstract Soluble starch synthases and branching enzymes were partially purified from developing leaves and kernels of maize using DEAE-cellulose chromatography. One form of starch synthase and two forms of branching enzyme were detected in leaves as compared to two forms of starch synthase and three forms of branching enzyme isolated from the kernels.

Molecular Structure of Starches from Maize Mutants Deficient in Starch Synthase III

Journal of Agricultural and Food Chemistry, 2013
Molecular structures of starches from dull1 maize mutants deficient in starch synthase III (SSIII) with a common genetic background (W64A) were characterized and compared with the wild type. Amylose content with altered structure was higher in the nonwaxy mutants (25.4-30.2%) compared to the wild type maize (21.5%) as revealed by gel permeation ...

Improved Cassava Starch by Antisense Inhibition of Granule-bound Starch Synthase I

Molecular Breeding, 2005
Cassava is a poor man's crop which is mainly grown as a subsistence crop in many developing countries. Its commercial use was first as animal feed (also known as tapioca), but has shifted since the late sixties to a source of native starch. The availability of native starches, which on the one hand do not require substantial chemical derivatisation and

Starch‐synthase III family encodes a tandem of three starch‐binding domains

Proteins: Structure, Function, and Bioinformatics, 2006
AbstractThe starch‐synthase III (SSIII), with a total of 1025 residues, is one of the enzymes involved in plants starch synthesis. SSIII from Arabidopsis thaliana contains a putative N‐terminal transit peptide followed by a 557‐amino acid SSIII‐specific domain (SSIII‐SD) with three internal repeats and a C‐terminal catalytic domain of 450 amino acids ...

Natural variation in rice starch synthase IIa affects enzyme and starch properties

Functional Plant Biology, 2004
The natural variation in starch synthase IIa (SSIIa) of rice (Oryza sativa L.) was characterised using near-isogenic lines (NILs). SSIIa is a candidate for the alk gene regulating the alkali disintegration of rice grains, since both genes are genetically mapped at the same position on chromosome 6 and related to starch properties.

Effects of Homoeologous Wheat Starch Synthase IIa Genes on Starch Properties

Journal of Agricultural and Food Chemistry, 2012
Near-isogenic lines (NILs) of the eight haplotypes of starch synthase IIa (SSIIa) were used to analyze the effects of SSIIa gene dosage on branch chain length, gelatinization, pasting, retrogradation, and enzymatic hydrolysis of starches. Compared to wild-type, the amylopectin of lines missing one or more active SSIIa enzymes had increases in the ...

Contribution of sucrose synthase, ADP‐glucose pyrophosphorylase and starch synthase to starch synthesis in developing pea seeds

Plant, Cell & Environment, 1997
ABSTRACTUsing genetic variability existing amongst nine pea genotypes (Pisum sativum L.), the biochemical basis of sink strength in developing pea seeds was investigated. Sink strength was considered to be reflected by the rate of starch synthesis (RSS) in the embryo, and sink activity in the seed was reflected by the relative rate of starch synthesis (
