MeSH headings : Carbohydrate Conformation; Galactans / metabolism; Galactose / analogs & derivatives; Hydrogen-Ion Concentration; Hydrolysis; Kinetics; Mannans / chemistry; Mannans / metabolism; Mannose / chemistry; Mannosidases / chemistry; Models, Chemical; Models, Statistical; Plant Gums / metabolism; Polysaccharides / chemistry; Rheology / methods; Time Factors; alpha-Galactosidase / chemistry
topics (OpenAlex): Polysaccharides Composition and Applications; Polysaccharides and Plant Cell Walls; Proteins in Food Systems
TL;DR: A rheology-based kinetic model is developed to estimate the reaction rate constants and interpret synergistic effects of multiple enzyme contributions and reveals that both the native and the debranched guar have the same activation energy for beta-mannanase action, although debranching considerably increases the frequency of enzyme-guar interactions.

2006 article

Kinetics of Enzymatic Depolymerization of Guar Galactomannan

Mahammad, S., Prud'homme, R. K., Roberts, G. W., & Khan, S. A. (2006, August 4). Biomacromolecules, Vol. 7, pp. 2583–2590.

By: S. Mahammad n, R. Prud'homme  n, G. Roberts n & S. Khan n 

MeSH headings : Biocompatible Materials / chemistry; Biotechnology / methods; Carbohydrate Sequence; Chromatography; Cyamopsis / chemistry; Enzymes / pharmacology; Galactose / analogs & derivatives; Kinetics; Mannans / chemistry; Models, Chemical; Models, Statistical; Models, Theoretical; Molecular Sequence Data; Polymers / chemistry; Time Factors
topics (OpenAlex): Polysaccharides Composition and Applications; Biofuel production and bioconversion; Polysaccharides and Plant Cell Walls
TL;DR: A new mathematical model based on Michaelis Menten (MM) kinetics is developed to predict the changes in molecular weight distribution (MWD) during the enzymatic depolymerization of guar galactomannan, and analyses confirm that an increase in PDI during the depolymersization is not necessarily due to nonrandom scission, as previously concluded.
