Serine/threonine kinases (STKs) regulate the synthesis of capsular polysaccharide in bacteria through unclear mechanisms. Here, Tang et al. identify a protein that is phosphorylated by an STK and modulates the activity of a phosphoregulatory system in Streptococcus suis, thus linking STKs to capsular polysaccharide synthesis.
