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

hysAHyaluronate lyase; Belongs to the polysaccharide lyase 8 family. (807 aa)    
Predicted Functional Partners:
ABD31482.1
Hypothetical protein.

spa
Protein A; Plays a role in the inhibition of the host innate and adaptive immune responses. Possesses five immunoglobulin-binding domains that capture both the fragment crystallizable region (Fc region) and the Fab region (part of Ig that identifies antigen) of immunoglobulins. In turn, Staphylococcus aureus is protected from phagocytic killing via inhibition of Ig Fc region. In addition, the host elicited B-cell response is prevented due to a decrease of antibody-secreting cell proliferation that enter the bone marrow, thereby decreasing long-term antibody production. Inhibits osteoge [...]

sdrC
sdrC protein, putative; Cell surface-associated calcium-binding protein which plays an important role in adhesion and pathogenesis. Mediates interactions with components of the extracellular matrix such as host NRXN1 to promote bacterial adhesion.
   
  
 0.570
icaA
Intercellular adhesion protein A, putative; N-acetylglucosaminyltransferase that catalyzes the polymerization of single monomer units of UDP-N-acetylglucosamine to produce the linear homopolymer poly-beta-1,6-N-acetyl-D-glucosamine (PNAG, also referred to as PIA), a biofilm adhesin polysaccharide. Requires IcaD for full activity (By similarity).
  
 
 0.506
icaB
icaB protein, putative; Catalyzes the N-deacetylation of poly-beta-1,6-N-acetyl-D- glucosamine (PNAG, also referred to as PIA), a biofilm adhesin polysaccharide. N-deacetylation is crucial for attachment of the polysaccharide to the bacterial cell surface; it leads to the introduction of positive charges in the otherwise neutral PIA polymer, allowing electrostatic interactions (By similarity).

Transcriptional regulator, merR family, putative.

hlb
Truncated beta-hemolysin; Bacterial hemolysins are exotoxins that attack blood cell membranes and cause cell rupture. Beta-hemolysin is a phospholipase C with specific activity toward sphingomyelins. Has a high specificity for sphingomyelin, hydrolyzes lysophosphatidylcholine at a much lower rate, but has no activity towards phosphatidylcholine, phosphatidylethanolamine, or phosphatidylserine; Belongs to the neutral sphingomyelinase family.

sspA
Glutamyl endopeptidase precursor, putative; Preferentially cleaves peptide bonds on the carboxyl-terminal side of aspartate and glutamate. Along with other extracellular proteases it is involved in colonization and infection of human tissues. Required for proteolytic maturation of thiol protease SspB and inactivation of SspC, an inhibitor of SspB. It is the most important protease for degradation of fibronectin-binding protein (FnBP) and surface protein A, which are involved in adherence to host cells. May also protect bacteria against host defense mechanism by cleaving the immunoglobu [...]

sdrD
sdrD protein, putative; Cell surface-associated calcium-binding protein which plays an important role in adhesion and pathogenesis. Mediates interactions with components of the extracellular matrix such as host DSG1 to promote bacterial adhesion to host cells. Contributes to the resistance to killing by innate immune components such as neutrophils present in blood and thus attenuates bacterial clearance.
     
 0.444
icaC
Intercellular adhesion protein C, putative; Presumably involved in the export of the biofilm adhesin polysaccharide poly-beta-1,6-N-acetyl-D-glucosamine (PNAG, also referred to as PIA) across the cell membrane.
