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.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

yqfFPutative membrane associate hydrolase; Probably has phosphodiesterase (PDE) activity against cyclic- di-AMP (c-di-AMP); may be the major c-di-AMP PDE in the cell. In B.subtilis c-di-AMP is a second messenger that mediates growth, DNA repair and cell wall homeostasis; it is toxic when present in excess. (711 aa)    
Predicted Functional Partners:
cdnD
Phosphodiesterase acting on cyclic dinucleotides; Has phosphodiesterase (PDE) activity against cyclic-di-AMP (c-di-AMP) and to a much lesser extent against cyclic-di-GMP (c-di-GMP) in the DHH/DHHA1 domains. Also has ATPase activity, probably via the GGDEF domain. Overexpression leads to increased sensitivity to methyl methanesulfonate (MMS) and H(2)O(2). Overexpression leads to extreme sensitivity to the beta-lactam antibiotic cefuroxime (CEF), probably dependent on PDE activity. May monitor cellular heme or NO levels. In B.subtilis c-di-AMP is a second messenger that mediates growth, [...]

ybbP
Putative enzyme with DAC domain protein; One of 3 paralogous diadenylate cyclases (DAC) in this bacteria, catalyzing the condensation of 2 ATP molecules into cyclic di-AMP (c-di-AMP) (Probable). Upon expression in E.coli leads to c-di- AMP synthesis. Probably the main producer of c-di-AMP for the cell; is probably implicated in control of peptidogylcan synthesis. In B.subtilis c-di-AMP is a second messenger that mediates growth, DNA repair and cell wall homeostasis; it is toxic when present in excess.

yojJ
Putative enzyme with DAC domain; One of 3 paralogous diadenylate cyclases (DAC) in this bacteria, catalyzing the condensation of 2 ATP molecules into cyclic di-AMP (c-di-AMP) (Probable). Upon expression in E.coli leads to c-di- AMP synthesis. Overexpression of the hyperactive mutant (L44F) in the absence of c-di-AMP phosphodiesterase GdpP leads to growth defects in log phase (long curly cell filaments) that disappear upon sporulation; spore formation is normal, showing sporulation is insensitive to the excess c-di-AMP. In B.subtilis c-di-AMP is a second messenger that mediates growth, [...]

yqfG
Putative metal-dependent hydrolase; Single strand-specific metallo-endoribonuclease involved in late-stage 70S ribosome quality control and in maturation of the 3' terminus of the 16S rRNA.
  
  
 0.893
dgkA
Undecaprenol kinase; Catalyzes the phosphorylation of undecaprenol in vitro, which is probably the physiological substrate. Exhibits no detectable activity against other substrates such as monoacylglycerol, ceramide, or diacylglycerol (DAG). Appears indispensable for the maintenance of spore stability and viability in B.subtilis.
 
  
 0.886
ybbR
Conserved hypothetical protein; Upon coexpression in E.coli stimulates the diadenylate cyclase activity of CdaA about 20-fold. In B.subtilis c-di-AMP is a second messenger that mediates growth, DNA repair and cell wall homeostasis; it is toxic when present in excess.
   
  
 0.853
glmM
Phosphoglucosamine mutase; Catalyzes the conversion of glucosamine-6-phosphate to glucosamine-1-phosphate (By similarity). Glucosamine-1-phosphate is used for cell wall biosynthesis (Probable); Belongs to the phosphohexose mutase family.

ktrA
Potassium uptake protein; Catalytic subunit of the KtrAB potassium uptake transporter. The 2 major potassium transporter complexes KtrAB and KtrCD confer resistance to both suddenly imposed and prolonged osmotic stress.

ydaO
Putative metabolite transporter; High-affinity potassium transporter.
      
 0.729
ktrC
Potassium uptake protein; Catalytic subunit of the KtrCD potassium uptake transporter. The 2 major potassium transporter complexes KtrAB and KtrCD confer resistance to both suddenly imposed and prolonged osmotic stress.
