Conserved protein kinase domains and their presence in chloroplast-localized protein kinases. (A) Illustration of the 11 highly conserved protein kinase domains according to Hanks et al. (1988), highlighting the ATP-binding motifs in subdomain I and II and essential catalytic residues in subdomains II, VI, and VII. (B) Alignment of the ‘classical’ protein kinases STN7 and cpCK2 with the unusual kinases PPK and the ABC1 kinases. The ATP-binding sites are highlighted in subdomain I and the essential catalytic residues are indicated in subdomains II, VI, and VII, respectively. A consensus sequence for homologous regions is displayed below.
