Computational Analysis of Binding Energy and Interactions between Molybdenum Insertase: Geph-G and Geph-E Domain with Molybdopterin (MPT) in the Biosynthesis of Molybdenum Cofactor

Abstract

Gephyrin, a postsynaptic protein self-amasses to shape a scaffold that anchor glycine and γ-aminobutyric acid Type A receptors (GABAAR) to the cytoskeleton, guaranteeing the accurate accumulation of postsynaptic receptors at the opportune spot. In vertebrates gephyrin is basically composed into an N-terminal G-domain and a C-terminal E-domain associated by a central linker region or C-domain. All three domains of gephyrin work in a synergic manner and neuronal and non-neuronal functions are performed by this protein. One of the numerous jobs of gephyrin is the biosynthesis of molybdenum cofactor (MOCO). The exact mechanism and binding actions of molybdenum Insertase (consisting of gephyrin G (Geph-G) and E (Geph-E) domains) are currently obscure and require further research; so as to have a superior comprehension of the metal exchange reaction between Copper (Cu) particle (ion) and molybdate (MoO4-2). Docking studies and molecular dynamic simulations were completed to determine the binding energies and interaction patterns as part of a function prediction for gephyrin, as the relative orientation of a ligand with a protein may influence the kind of signal created and anticipate both the quality and type of signal produced. Due of this computational investigation, it has been presumed that the metal containing pterin (MPT) is precarious with or without the copper particle subsequently outlining the job of copper particle only as a decoy utilized for substitution. Once adenylated the metal containing pterin (MPTAMP) stabilizes and copper particle is now able to be discharged and the ligand is passed along to the second protein domain Geph-E, where inclusion of molybdenum (Mo) as molydate (MoO4-2) happens.
