Fig. 5From: SCMBYK: prediction and characterization of bacterial tyrosine-kinases based on propensity scores of dipeptidesSchematic organization of BY-kinases and their active sites. a Organization of BY-kinases in Proteobacteria and Firmicutes. Walker motifs (A, A’ and B), extracellular hairpin domains, and transmembrane spans are colored yellow, purple, and blue, respectively. In Proteobacteria, the extracellular loop and the intracellular domain are parts of the same protein, whereas in Firmicutes they are linked via specific protein-protein interactions. b Sequence logos of signature amino-acid sites of top-30-scored BY-kinases. “GK” in Walker A, “DXDXR” in Walker A’, and “DXPPX” in Walker B are indicated by larger lettersBack to article page
