Predicting and testing determinants of histidine-kinase functions by leveraging protein sequence information by Orr Ashenberg Submitted to the Program of Computational and Systems Biology on September 06, 2012 in partial fulfillment of the requirements for the degree of NME1/2 protein histidine kinase functions are in yellow, pHis enzyme intermediates are in green, phosphohistidine phosphatases are in white and pHis substrates are in bold. This type of histidine kinase is called a hybrid histidine kinase in which the phosphotransfer occours from the conserved histidine to the conserved aspartate residue, present within the same protein (Fig. The kinase domain of the osmosensing histidine kinase EnvZ of Escherichia coli consists of two domains: domain A (67 residues) responsible for histidine phosphotrans-fer and dimerization, and domain B (161 residues) responsible for the catalytic and ATP-binding func-tion. The phosphotransfer to the response regulator is mediated by an additional protein, the histidine-containing . Membrane-bound histidine kinase Cytokinin-independet 1 (CKI1) is a member of the Multistep phosphorelay (MSP) signalling pathway in Arabidopsis. Memorial Union 3505. The canonical two-component system (TCS) utilizes two distinctive signaling proteins, a membrane-bound sensor histidine kinase (HK) and a cytoplasmic response regulator (RR) protein. Histidine kinases are found in most bacteria, archaea, and lower eukaryotic species such as slime molds, fungi, and plants where they function in two-component signal transduction pathways. 2.2.

Yeasts were incubated for 24 h under constant agitation of 180 rpm at . Most species encode numerous paralogous histidine kinases that exhibit significant structural similarity. served aspartate residue. This system is activated at low temperature and maintains membrane lipid fluidity upon temperature variations. Histidine Kinase Inhibitor Susceptibility. To assess the function of the five MdCHKs as cytokinin receptors, we exploited the S. cerevisiae sln1Δ deletion mutant strain which carries a lethal mutation in the SLN1 gene encoding its unique osmosensing histidine kinase (Inoue et al., 2001). Depending on the signal, HK interconverts between the kinase and phosphatase states. Its structure reveals that the light-oxygen-voltage (LOV) sensor domain both controls kinase activity and prevents dimerization by binding one side of a dimerization/histidine phosphotransfer-like (DHpL) do-main. Functions as a histidine kinase and transmits the stress signal to a downstream MAPK cascade. In orthodox two-component signaling, a histidine kinase protein autophosphorylates on a histidine residue in response to an extracellular signal, and the phosphoryl group is subsequently transferred to an aspartate residue on the receiver domain of a response regulator.In phosphorelays, the "hybrid" histidine kinase contains an internal aspartate-containing receiver domain to which . Rogers, Anna. Interestingly, these mutants retained 50-70% of their activity upon treatment with fludioxonil indicating that fludioxonil-induced poly-HAMP-mediated conformational changes were .

These RHKs respond to secreted signaling peptides, which bind to the sensor domain to initiate the transmembrane signal that activates the intracellular histidine kinase (HK). Histidine kinase EnvZ, a transmembrane osmotic sensor for Escherichia coli, is a bifunctional enzyme having OmpR (its cognate response regulator) kinase and phosphorylated OmpR (OmpR-P) phosphatase activities.

Possible functions of the histidine kinase in osmosensing in plants are discussed. We examine signaling through the HAMP domain of an E. coli histidine kinase, CpxA, by constructing a small library of structurally diverse inputs into the HAMP domain and evaluate the resulting autokinase activity as a function of several S-helix point mutations. MHZ1/OsHK1 encodes a histidine kinase of 936 amino acids, with a histidine kinase domain (amino acids 365 to 655) and a receiver domain (amino acids 817 to 961) (Fig. When genomes of higher eukaryotes began to be sequenced, it did not appear that they contained two-component histidine kinase system homologues, apart from a couple of related . Huebner and Matthews (1985) found phosphorylation of histidine residues, both in histones and in cytoplasmic proteins, that does not correspond to the characteristics of the histidine kinases found in bacterial systems.

Another domain common to histidine kinases is the HAMP [22] , type P [23] , or Duf5 (Sanger Center nomenclature) domain that is located just cytoplasmic to transmembrane domains. The vast majority of HKs are homodimers that exhibit autokinase, phosphotransfer, and phosphatase activity.HKs can act as cellular receptors for signaling molecules in a way analogous . Histidine kinase domain profile. Notably, there is at least one RHK in Escherichia coli, UhpB, which contains 6-8 transmembrane helices and which is also thought to function as a homodimeric complex Previously, we identified hybrid histidine kinase BinK as a 44 strong negative regulator of V. fischeri biofilm regulation, and here we further explore the 45 function of BinK. Temperature‐dependent coronatine biosynthesis is regulated by a modified two‐component system, consisting of the response regulator, CorR, the histidine protein kinase CorS, and a third component, CorP. To elucidate the mechanism by which CorRSP functions, genetic, transcriptional, and biochemical analyses were applied, including in vitro . Histidine kinases allow bacteria, plants, and fungi to sense and respond to their environment. Kinase enzymes are a key component in various biochemical processes. Regulation of RR activity is usually achieved via its phosphorylation or dephosphorylation by a cognate histidine kinase (HK) [23,24]. Flavin-containing domains function as light-sensory modules in plant and algal phototropins and in fungal blue-light receptors. In the kinase state, HK transfers the phosphate from ATP to its own histidine amino acid and then to the RR's aspartate. RESULTS ATHK1 Is an Aradidopsis Hybrid-Type Histidine KinaseTo isolate histidine kinases, we used a polymerase chain reaction (PCR) strategy with degenerate oligonucleotide primers and cDNAs prepared from dehydrated Arabidopsis rosette plants. Bacteria sense and respond to their environment through a highly conserved assembly of transmembrane chemoreceptors (MCPs), the histidine kinase CheA, and the coupling protein CheW, hereafter termed "the chemosensory array".

Recently, Two-component signal transduction pathways consisting of a histidine kinase and a response regulator are used by prokaryotes to respond to diverse environmental and intracellular stimuli. histidine kinase functions in concert with a tran-scription factor, termed the response regulator.1 When a histidine kinase recognizes its cognate signal, usually a small effector molecule, it autopho-sphorylates by transferring the terminal phosphate of ATP to a conserved histidine residue to form a phosphoimidazoleadduct.Thisphosphatemoietyis J Mol Biol 386 , 163-177, doi: 10.1016/j.jmb.2008.12.006 (2009). The mechanisms and functions of these kinases, their cognate response regulators and associated phosphorelay proteins are becoming increasingly well understood. The Bacillus subtilis KinA protein is a histidine protein kinase that controls the commitment of this organism to sporulate in response to nutrient deprivation and several other conditions. The histidine-kinase sensors are known to function as a dimer, whereas Tar, a chemosensor for aspartate, may, be able to transduce a signal within a single cytoplasmic domain (6, 7).
