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

sbnAConserved hypothetical protein; Catalyzes the synthesis of N-((2S)-2-amino-2-carboxyethyl)-L- glutamate (ACEGA) from O-phospho-L-serine and L-glutamate. Involved in the biosynthesis of L-2,3-diaminopropionic acid (L-Dap), a precursor of staphyloferrin B and antibiotics. (281 aa)    
Predicted Functional Partners:
sbnB
Ornithine cyclodeaminase, putative; Catalyzes the hydrolysis of N-((2S)-2-amino-2-carboxyethyl)- L-glutamate (ACEGA) to form L-2,3-diaminopropionic acid and 2- oxoglutarate. Involved in the biosynthesis of L-2,3-diaminopropionic acid (L-Dap), a precursor of staphyloferrin B and antibiotics. Belongs to the ornithine cyclodeaminase/mu-crystallin family.
  
 
 0.997
sbnI
Conserved hypothetical protein; Free serine kinase that uses ATP to phosphorylate L-serine to yield O-phospho-L-serine and ADP. O-phospho-L-serine serves as a substrate for SbnA and is a precursor for staphyloferrin B biosynthesis. Is also a DNA-binding regulatory protein that senses heme to control gene expression for siderophore biosynthesis. Binds to DNA within the sbnC coding region and is required for expression of genes in the sbn operon from sbnD onward.
    
 0.996
sbnC
Conserved hypothetical protein; Catalyzes the condensation of L-2,3-diaminopropionyl-citryl- diaminoethane and 2-oxoglutarate to form staphyloferrin B, the fourth and last step in staphyloferrin B biosynthesis.
  
  
 0.932
ABD29659.1
Serine acetyltransferase, putative.
 
 0.932
sbnF
Conserved hypothetical protein; Catalyzes the condensation of L-2,3-diaminopropionic acid (L- Dap) and citryl-diaminoethane to form L-2,3-diaminopropionyl-citryl- diaminoethane, the third step in staphyloferrin B biosynthesis.
  
  
 0.931
sbnE
Conserved hypothetical protein; Catalyzes the synthesis of citryl-L-2,3-diaminopropionic acid from L-2,3-diaminopropionic acid (L-Dap) and citrate, the first step in staphyloferrin B biosynthesis.
  
  
 0.914
sbnH
Conserved hypothetical protein; Catalyzes the decarboxylation of citryl-L-2,3- diaminopropionic acid to citryl-diaminoethane, the second step in staphyloferrin B biosynthesis; Belongs to the Orn/Lys/Arg decarboxylase class-II family.
  
  
 0.914
cysS
cysteinyl-tRNA synthetase; Belongs to the class-I aminoacyl-tRNA synthetase family.
  
 0.909
sbnD
Conserved hypothetical protein; Involved in staphyloferrin B secretion. Belongs to the major facilitator superfamily.
  
 
 0.907
ABD29264.1
Conserved hypothetical protein; Belongs to the HpcH/HpaI aldolase family.
  
  
 0.845
