Deskripsi

The Mycobacterium tuberculosis kinase PknB regulates essential cell functions via interactions with muropeptides. Here the authors identify interaction sites in the extracytoplasmic PASTA domain and show that abrogation of ligand binding leads to a hyper-activated kinase, causing loss of homeostasis and cell death.
