Journal ArticleDOI
From glycogen to amylopectin: a model for the biogenesis of the plant starch granule.
Steven G. Ball,Hanping Guan,Martha G. James,Alan M. Myers,Peter L. Keeling,Grégory Mouille,Alain Buléon,Paul Colonna,Jack Preiss +8 more
TL;DR: The induced fit hypothesis for starch growth only requires the understanding of amylopectin cluster synthesis as proposed in the two dimensional model.
Journal ArticleDOI
Branching of amylose by the branching isoenzymes of maize endosperm
TL;DR: In this article, the Park-Johnson method was used to determine the reducing power of branching enzymes with reduced amylose as the substrate, and the results showed that the specific activities were highest for BE I and lowest for BE IIa and IIb.
Journal ArticleDOI
Differentiation of the Properties of the Branching Isozymes from Maize (Zea mays).
Hanping Guan,Jack Preiss +1 more
TL;DR: This study presents the first evidence that the BE isoforms differ in their action on amylopectin, and the implication of these findings to the mechanism of amylipectin synthesis in vivo is discussed.
Journal ArticleDOI
Identification of the Soluble Starch Synthase Activities of Maize Endosperm
Heping Cao,Jennifer Imparl-Radosevich,Hanping Guan,Peter L. Keeling,Martha G. James,Alan M. Myers +5 more
TL;DR: DU1 and zSSI accounted for the great majority of soluble SS activity present in developing endosperm, and the relative activity of the two isozymes did not change significantly during the starch biosynthetic period.
Journal ArticleDOI
Comparing the properties of Escherichia coli branching enzyme and maize branching enzyme.
TL;DR: The significance of minimum chain-length requirement by SBE is discussed in setting the invariant size of amylopectin cluster size (9 nm) and the differences between SBEI and SBEII in the size of chains transferred are defined.
