STRINGSTRING
STRING protein interaction network
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.

Score
disADiadenylate cyclase; Participates in a DNA-damage check-point that is active prior to asymmetric division when DNA is damaged. Forms globular foci that rapidly scan along the chromosomes during sporulation, searching for lesions. Its ability to scan through the chromosome rapidly is due to its non-specific DNA- binding. When a lesion is present, DisA pauses at the lesion site. This triggers a cellular response that culminates in a temporary block in sporulation initiation. It is required, at least partially, to inhibit the activity of the transcription factor spo0A, which controls, amo [...] (360 aa)    
Predicted Functional Partners:
radA
DNA repair protein; DNA-dependent ATPase involved in processing of recombination intermediates, plays a role in repairing DNA breaks. Stimulates the branch migration of RecA-mediated strand transfer reactions, allowing the 3' invading strand to extend heteroduplex DNA faster. Binds ssDNA in the presence of ADP but not other nucleotides, has ATPase activity that is stimulated by ssDNA and various branched DNA structures, but inhibited by SSB. Does not have RecA's homology-searching function.

yacL
Putative membrane protein; An RNase; In the central section; belongs to the PINc/VapC protein family.
  
  
 0.936
mcsA
Activator of protein kinase McsB; Activates the phosphorylation activity of the protein- arginine kinase McsB. Is required for the delocalization of competence proteins from the cell poles.
  
  
 0.887
mcsB
Protein tyrosine kinase; Catalyzes the specific phosphorylation of arginine residues in a large number of proteins. Is part of the bacterial stress response system, where it is involved in regulating the global heat shock repressor CtsR; phosphorylates arginine residues in the winged helix- turn-helix domain of CtsR, thereby preventing its binding to DNA and consequently inducing the expression of repressed genes. The transcriptional repressor HrcA, the chaperone GroEL, the unfoldase ClpC, together with several ribosomal subunits, represent other physiological targets of McsB under str [...]

ispD
2-C-methyl-D-erythritol 4-phosphate cytidylyltransferase, nonmevalonate isoprenoid pathway; Catalyzes the formation of 4-diphosphocytidyl-2-C-methyl-D- erythritol from CTP and 2-C-methyl-D-erythritol 4-phosphate (MEP).
  
    0.864
clpC
Class III stress response-related ATPase, AAA+ superfamily; Competence gene repressor; required for cell growth at high temperature. Negative regulator of comK expression. May interact with MecA to negatively regulate comK; Belongs to the ClpA/ClpB family. ClpC subfamily.
  
  
 0.809
ctsR
Transcriptional regulator; Controls the expression of the cellular protein quality control genes clpC, clpE and clpP, as well as mcsA and mcsB. Acts as a repressor of these class III stress genes by binding to a directly repeated heptanucleotide operator sequence (A/GGTCAAA NAN A/GGTCAAA). After heat shock, CtsR is degraded by the ClpCP and ClpEP proteolytic systems, ensuring the derepression of clpE, clpP and the clpC operon. CtsR negatively autoregulates its own synthesis.

ypbG
Putative phosphoesterase; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme.
   
  
 0.780
ispF
2-C-methyl-D-erythritol-2,4-cyclodiphosphate synthase; Involved in the biosynthesis of isopentenyl diphosphate (IPP) and dimethylallyl diphosphate (DMAPP), two major building blocks of isoprenoid compounds. Catalyzes the conversion of 4-diphosphocytidyl-2- C-methyl-D-erythritol 2-phosphate (CDP-ME2P) to 2-C-methyl-D-erythritol 2,4-cyclodiphosphate (ME-CPP) with a corresponding release of cytidine 5-monophosphate (CMP); Belongs to the IspF family.
  
    0.736
gltX
glutamyl-tRNA synthetase; Catalyzes the attachment of glutamate to tRNA(Glu) in a two- step reaction: glutamate is first activated by ATP to form Glu-AMP and then transferred to the acceptor end of tRNA(Glu).
