Inhaltsangabe

Research into plant biopolymers, their structural characteristics and related physicochemical and functional properties is of increasing significance in the modern world. This is particularly true in relation to sustainable agriculture, environmentally friendly processes and new technology requirements and safe products. This unique book reports on the very latest research on plant biopolymer science, from biosynthesis through to applications. It describes specifically developments in the study of the biosynthesis of macromolecules and biopolymer design, going on to model systems such as biopolymer assemblies, interfaces and interphases. Finally, a discussion of multiphasic systems shows how these concepts may be extended to everyday applications. With contributions drawn from the international scientific community, Plant Biopolymer Science: Food and Non-Food Applications provides an overview of the state-of-the-art for a variety of readers, which will include students, researchers and teachers in academia to professionals in industry and government agencies.

CHAPTER 1

Biochemical Mechanisms of Synthesis of (1 -> 3), (1 -> 4) β-D--D-Glucans: Cellulose Synthase with an added Twist?

1 Introduction

Synthases of all polymers containing (1 -> 4) β-linked glucosyl, mannosyl and xylosyl residues have overcome a substrate-orientation problem in catalysis because this particular linkage requires that each of these sugar units be inverted nearly 180° with respect to its neighbors. We and others have proposed that this problem is solved by two modes of glycosyl transfer within a single catalytic subunit to generate disaccharide units, which maintain the proper orientation without rotation or re-orientation of the synthetic machinery in 3-dimensional space. A variant of the strict (1 -> 4) β-D-linkage structure is the mixed-linkage (1 -> 3),(1 -> 4) βD-glucan (β-glucan), a growth specific cell wall polysaccharide found in grasses and cereals and other members of the Poales. β-Glucan is composed primarily of cellotriosyl and cellotetraosyl units linked by single (1 -> 3) β-linkages. In reactions in vitro at high substrate concentration, a polymer composed of almost entirely cellotriosyl and cellopentosyl units is made. These results support a model in which three modes of glycosyl transfer occur within the synthase complex, but the generation of odd numbered units demands that they are connected by (1 -> 3) β-linkages and not (1 -> 4) β. We propose that a central part of the β-glucan synthase complex is derived from an ancestral cellulose synthase, and that an additional glycosyl transferase associates with it to generate these odd numbered cellodextrin units. In contrast to xyloglucan and pectin synthases, which are completely enclosed within the lumen of the Golgi apparatus, we provide evidence from limited proteolysis experiments that the catalytic domain of β-glucan synthase is oriented to the cytosolic side of the Golgi membrane and extrudes β-glucan through a channel into the lumen. Thus, the β-glucan synthase is the topological equivalent of cellulose synthase.


1.1 The Unique Twisted Structure of β-Glucan

Mixed-linkage (1 -> 3),(1 -> 4)β-D-glucan (β-glucan) is a plant cell wall polysaccharide specific to grasses and cereals that appears during cell expansion. In all cereal endosperm walls, the ratio of cellotriosyl and cellotetraosyl units is...
