    Abstract

    The physiologic roles and the substrates of the Mycobacterium tuberculosis (Mtb) serine/threonine kinases are largely unknown. Here, we report six novel interactions of PknB, PknD, PknE, and PknF with the Forkhead-Associated (FHA) domains of Rv0020c and the putative ABC transporter Rv1747. Purified PknB and PknF kinase domains phosphorylated multiple FHA-domain proteins in vitro. Although they remain to be verified in vivo, these reactions suggest a web of interactions between STPKs and FHA domains.
