In-silico analysis of Salmonella typhimurium and E.coli Methionyl tRNA synthetase at primary, secondary, tertiary level with protein disorder and functional association of differences
The identification changes in amino acid for same protein in closely related species are necessary in order to identify its effect at various structural and functional levels. Salmonella typhimurium and E.coli Methionyl tRNA synthetase taken in current study as these bacteria are closely related to each other and have fewer differences in amino acid sequences for MetG. This study helps to identify various structural and functional differences at primary, secondary and tertiary levels, with functional differences by Docking study with Methionine. Study involves analysis of differences based on observation of differences in modeled 3D protein for sequences available at NCBI and its comparison with Known 3D structure. As sequences difference are in functional protein from non-mutant species, the differences are analysed in context of Primary, secondary, tertiary structure differences, Disorder differences, and docking differences.
