1MRU - PubMed Abstract: 
A family of eukaryotic-like Ser/Thr protein kinases occurs in bacteria, but little is known about the structures and functions of these proteins. Here we characterize PknB, a transmembrane signaling kinase from Mycobacterium tuberculosis. The intracellular PknB kinase domain is active autonomously, and the active enzyme is phosphorylated on residues homologous to regulatory phospho-acceptors in eukaryotic Ser/Thr kinases ...
