  • Cellulose is a (14)--D-glucan

  • Occurs in the form of microfibrils In primary walls dimensions 3-3.5 nm wide crystallites (~ 25 cellulose molecules 5 x 5, rather than 36)

  • From: Brett & Waldron (1996) Physiol. & biochemistry of plant cell walls, p 78

    Synthesized from an activated donor: UDP-glucose

  • Location of synthesis plasma membraneStudies with the transmission electron microscope (TEM) of the plasma membranes of all land plants after preparation using freeze fracturing showed rosettes of 6 particles

    From: Delmer, D. P. (1999). Annual Review Plant Physiology Plant Molecular Biology, 50, 245-276.

  • Rosettes are often located at the ends of cellulose microfibrilsParticles of rosette contain cellulose synthases (immunogold labelling)

    From: Taiz and Zeiger (2006) Plant Physiology 4 th edition. Sinauer, Sunderland (USA).

  • Direction of cellulose microfibrils follows that of underlyingmicrotubules From: Lloyd, C. (2006). Science, 312, 1482-1483.Heath, I. B. (1974). A unified hypothesis for the role of membrane bound enzyme complexes and microtubules in plant cell wall synthesisJournal of Theoretical Biology 48, 445-449.Paredez et al. (2006).

  • But when plasma membranes or mixed membranes are isolated from developing cotton fibres and incubated with UDP-glucose, labelled (14C or 3H), label is mostly incorporated in another polysaccharide: callose [(13)--glucan]. [Biochemical approach]

  • Delmer (1995) showed that if feed 14C-sucrose to developing cotton fibres 'permeabilized' with digitonin (a detergent):- Up to 60% of product cellulose- Rates of synthesis much higher than usual, approach in vivo rates. (Amor et al. 1995 PNAS USA 92, 9353-9357)At least half of sucrose synthase (SuSy) in cotton fibres tightly associated with plasma membrane.Catalyses:Sucrose + UDP UDP-Glc + FructoseSuggested SuSy forms a complex with cellulose synthase and channels C from sucrose to UDP-Glc to cellulose.

  • Cellulose synthesis in bacteriaSeveral genera of bacteria synthesize cellulose Gluconacetobacter xylinus (formerly Acetobacter xylinus) synthesizes massive amounts of extracellular cellulose as a pellicle.Used as a model organism.Unlike cellulose synthases of seed plants, can solubilize cellulose synthases with digitonin and obtain high rates of in vitro cellulose synthesis.

  • If solublized enzyme is incubated in vitro with UDP-Glc, cellulose fibrils visible in TEM form within 20-30 min.Operon of 4 genes involved in cellulose synthesis in A. xylinu
