title: In silico analysis of sequence-structure-function relationship of the Escherichia coli methionine synthase.
abstract: The molecular evolution of various metabolic pathways in the organisms can be employed for scrutinizing the molecular aspects behind origin of life. In the present study, we chiefly concerned about the sequence-structure-function relationship between the E. coli methionine synthase and their respective animal homologs by In-silico approach. Using homology prediction technique, it was observed that only 79 animal species showed similarity with the E. coli methionine synthase. Also, multiple sequence alignment depicted only 25 conserved patterns between the E. coli methionine synthase and their respective animal homologs. Based on that, Pfam analysis identified the protein families of 22 conserved patterns amongst the attained 25 conserved patterns. Furthermore, the 3D structure was generated by HHpred and evaluated by corresponding Ramachandran plot specifies 93% of the ϕ and □ residues angles in the most ideal regions. Hence, the designed structure was established as good quality model for the full length of E. coli methionine synthase.
