Conformational features of galacturonans. II. Configurational statistics of pectic polymers.

Abstract:

:The unperturbed dimensions of poly-alpha-D-galacturonic acid (PGA) as a function of the degree of polymerization (n) and degree of ionization (%GalA-) have been determined by molecular mechanics and Monte Carlo methods. Chain extensions appear to depend substantially on contributions arising from local redistributions of charge on charged and uncharged galacturonic acid residues. Inclusion of methyl-esterified galacturonic acid units results in increased chain extensions. Incorporation of alpha-(1-->2)-L-rhamnose units causes abrupt changes in chain propagation and a reduction in calculated chain extension.

  • Distortions in protein helices.

    abstract::alpha-helices are the most common secondary structures in observed proteins. However, they are not always found in ideal helical conformation and they often exhibit structural distortions. Quantification of these irregularities become essential in understanding the packing of helices and therefore, their role in the f...
