Abstract
Methane, along with carbon dioxide and nitrogen oxides, is a key greenhouse gas contributing significantly to the global concern over climate change. This study investigated the anti-methanogenic properties of pyrogallol in Spirulina platensis using molecular docking and dynamics simulation on methyl-coenzyme M reductase (MCR). The Swiss ADME web server was used to identify pyrogallol's absorption, distribution, metabolism, and excretion (ADME) properties. Molecular docking studies were conducted using UCSF Chimera with the Vina script as the executor. The docking results were further analyzed through molecular dynamics simulation using Gromacs-2024. ADME analysis indicated that pyrogallol meets Lipinski’s Rule of Five. Docking studies revealed that pyrogallol has a binding affinity of 4.6 kJ/mol with 2 hydrogen bonds and 1 hydrophobic interaction. Additionally, the MCR-pyrogallol simulation results showed fluctuating root mean square deviation (RMSD) values that stabilized at t = 26,200 until the end of the simulation with an average value of 2.50 nm. Moreover, the hydrogen bonds formed during the simulation fluctuated, with no bonds observed for more than 75% of the simulation time. The energy released during the simulation reached –300.24 kJ/mol with an average of –5.19 kJ/mol. In conclusion, the pyrogallol compound in Spirulina plantensis can potentially inhibit the MCR enzyme, thereby reducing methane production and mitigating the impact of climate change.
