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

ybbPCyclic di-AMP synthase CdaA; 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 (273 aa)    
Predicted Functional Partners:
ybbR
CdaA regulatory protein CdaR; 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

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
     
 0.990
cdnD
Cyclic-di-AMP phosphodiesterase GdpP; 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, DNA repair [...]

yqfF
Cyclic-di-AMP phosphodiesterase PgpH; 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

ydaO
Uncharacterized amino acid permease YdaO; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pt: putative transporter
      
 0.832
ktrA
Ktr system potassium uptake protein A; 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

yuxH
Uncharacterized protein YuxH; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe : putative enzyme

rsiW
Anti-sigma-W factor RsiW; The anti-sigma factor for extracytoplasmic function (ECF) sigma factor sigma-W (SigW). Holds SigW, its cognate ECF sigma factor, in an inactive form until released by regulated intramembrane proteolysis (RIP). SigW and RsiW mediate cell response to cell wall stress. RIP occurs when an extracytoplasmic signal triggers a concerted proteolytic cascade to transmit information and elicit cellular responses. The membrane-spanning regulatory substrate protein is first cut periplasmically (site-1 protease, S1P, PrsW), then within the membrane itself (site-2 protease, [...]

sigW
ECF RNA polymerase sigma factor SigW; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. Sigma-W controls genes involved in response to cell envelope stress such as antimicrobial peptides, alkaline pH, transport processes and detoxification
     
 0.683
radA
DNA repair protein RadA; 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
