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

sbnBOrnithine 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. (336 aa)    
Predicted Functional Partners:
sbnA
Conserved 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.
  
 
 0.997
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.
 
 
 0.995
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.
 
 
 0.959
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.
 
 
 0.959
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.
 
 
 0.952
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.
     
 0.943
sbnD
Conserved hypothetical protein; Involved in staphyloferrin B secretion. Belongs to the major facilitator superfamily.
     
 0.915
ABD30949.1
Conserved hypothetical protein.
  
 
 0.915
proC
Pyrroline-5-carboxylate reductase; Catalyzes the reduction of 1-pyrroline-5-carboxylate (PCA) to L-proline.
   
 
 0.913
ABD31437.1
Arginase; Belongs to the arginase family.
  
 
 0.899
