| Summary: | Pectin is the focus of scientific interest due to both its physicochemical and biochemical properties, as well as its non-toxic nature. Methylation of pectin is a natural process that exists as part of the cell wall defence system against various pathogens. In this study the docking analysis was conducted to predict if methylation o affects the anticancer and antimicrobial properties of pectin and what extent. Four pectin derivatives with varying degrees of methylation and two sets of biomolecules were used. The first set included enzymes responsible for anticancer activity (HMGR, the AGE receptors, tumour protein p53 and oncogenic phosphatase SHP2), while the second set included those for antimicrobial activity (Salmonella Typhi TtsA, Pseudomonas aeruginosa Earp, Streptococcus mutans MetE and Staphylococcus aureus Cas9). The results indicated that the degree of methylation does not play a decisive role in the mentioned activities. because all bind to the same sites with similar binding energies. Additionally, it was shown that pectin derivatives have a higher binding affinity towards DNA than towards enzymes. Only the fully methylated derivative exhibited different behaviour, binding to a different binding site in the case of Streptococcus mutans MetE. |
