Figure 3From: Diversity in domain architectures of Ser/Thr kinases and their homologues in prokaryotesMultiple sequence alignment of the human guanylate cyclase, rat adenylate cyclase and GC-like domain of PKN2 of Myxococcus xanthus is shown. The residues conferring nucleotide specificity are shaded yellow. Conserved hydrophobic and charged residues are shaded green and grey respectively.Back to article page
