Complex Fluids in Biological Systemss that are highly hydrated. This article describes the physical basis of pectin hydration, setting it in the context of the hydration behaviour of polymers in general and polyelectrolytes in particular. The interplay between network expansion (driven by water uptake) and elastic resistance to deform

Rheology and Mechanics of the Cytoskeleton fractions extracted with 4M NaOH were characterised by HPSEC, uronic acid determination and methylation analysis. Substantial amounts of galacturonic acid could be detected indicating the presence of pectic substances. An enrichment of the pectic substances was achieved by degradation of the xylogl

Rheology and Mechanics of the Cytoskeletontructurally complex macromolecules that exist in nature. The biological basis for the diversity of pectic polymer structure is far from clear and understanding their complexity in the context of cell wall architecture and cell wall properties remains a major challenge. This chapter reviews recent wo

Hamed Hatami-Marbini,Mohammad R. K. Mofrad. So far, little is known about regulatory factors involved in pectin degradation. It appears that the pectinolytic regulatory system is more complex than the xylanolytic regulatory system, in which a general activating factor (XlnR) plays a central role. Some pectinolytic genes are expressed in res

In this chapter we give an overview of the results of these studies for a pectate and pectine lyase and a polygalacturonase..Detailed kinetic studies on pectate lyase have revealed that the substrate binds to the enzyme a
