Srinivas V, Kreft J, Gopal S., In silico horizontal gene transfer and functional motif in GshF protein of Listeria monocytogenes, Online J Bioinform, 13(1):14-26, 2012. Glutathione synthesis, a two step process in Listeria monocytogenes, is performed by a single Glutathione fusion protein (GshF). GshF comprises 776 amino acids with N terminal gammaglutamylcysteine ligase (GshA) and C terminal ATP grasp dependent domains. Amino acids 338 to 580 were horizontally gene transferred through a symbiotic relationship within the host and other bacteria. Flipping of unstructured proteins in eukaryotes during host pathogen interaction may have triggered fusion. In this study, a novel motif KPKX|S/T|TN in L. monocytogenes EGDe was identified in GshF/GshAB (Glutathione biosynthesis bifunctional protein) conserved in proteobacteria, bacteriodetes and firmicutes. The motif was present in the B-loop and residues were exposed. L. monocytogenes EGD-e motif consisted of phosphorylation residues which could regulate ligase activity.
