    Streptococcus pneumoniae carries a single Ser/Thr protein kinase gene stkP in its genome. Biochemical studies performed with recombinant StkP have revealed that this protein is a functional membrane-linked eukaryotic-type Ser/Thr protein kinase. Here, we demonstrate that the deletion of its extracellular domain negatively affects the stability of a core kinase domain. In contrast, the membrane anchored kinase domain and the full-length form of StkP were stable and capable of autophosphorylation. Furthermore, evidence is presented that StkP forms dimers through its transmembrane and extracellular domains

    Streptococcus pneumoniae má ve svém genomu jediný gen kódujícíc serin-threoninovou proteinkinasu StkP. Biochemické studie provedené s rekombinantní StkP prokázaly, že tento protein je funkční membránovou serin-threoninovou proteinkinasou eukaryotického typu. Prokázali jsme, že delece její extracelulární domény negativně ovlivňuje stabilitu domény kinázové. Naopak, kinázová doména zakotvená v membráně a celá StkP jsou stabilní a schopné autofosforylace. Dále, StkP vytváří dimery skrze transmembránovou a extracelulární domény
