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

TM_1873Ornithine decarboxylase; Similar to GB:AE000657 percent identity: 64.19; identified by sequence similarity; putative; Belongs to the Orn/Lys/Arg decarboxylase class-II family. (388 aa)    
Predicted Functional Partners:
speE
Spermidine synthase; Catalyzes the irreversible transfer of a propylamine group from the amino donor S-adenosylmethioninamine (decarboxy-AdoMet) to putrescine (1,4-diaminobutane) to yield spermidine. It has lower affinity and lower activity towards 1,3-diaminopropane, cadaverine (1,5-diaminopentane), agmatine, norspermidine and spermidine (in vitro).
  
 0.993
TM_0547
Aspartokinase II; Similar to PID:928811 SP:P53553 percent identity: 67.00; identified by sequence similarity; putative.
 
 0.770
speH
Conserved hypothetical protein; Catalyzes the decarboxylation of S-adenosylmethionine to S- adenosylmethioninamine (dcAdoMet), the propylamine donor required for the synthesis of the polyamines spermine and spermidine from the diamine putrescine; Belongs to the prokaryotic AdoMetDC family. Type 1 subfamily.
    
 0.636
TM_1518
Aspartokinase II; Similar to PID:928811 SP:P53553 percent identity: 64.96; identified by sequence similarity; putative; Belongs to the aspartokinase family.
  
 0.628
TM_0571
Heat shock serine protease, periplasmic; Similar to GB:U07352 GB:L09274 PID:497157 percent identity: 61.12; identified by sequence similarity; putative.
  
  
  0.563
hisI
phosphoribosyl-AMP cyclohydrolase / phosphoribosyl-ATP pyrophosphohydrolase; Similar to GB:AE000657 percent identity: 70.41; identified by sequence similarity; putative; In the C-terminal section; belongs to the PRA-PH family.
  
  
 0.514
guaA
GMP synthase; Catalyzes the synthesis of GMP from XMP.
  
  
 0.506
dapB
Dihydrodipicolinate reductase; Catalyzes the conversion of 4-hydroxy-tetrahydrodipicolinate (HTPA) to tetrahydrodipicolinate (Probable). Uses NADPH as a reductant with much more efficiency than NADH; Belongs to the DapB family.
 
 
 0.496
pgk/tpi
Phosphoglycerate kinase/triose-phosphate isomerase; Similar to PIR:S54289 percent identity: 99.69; identified by sequence similarity; putative; In the N-terminal section; belongs to the phosphoglycerate kinase family.
  
 
 0.494
TM_1523
Aspartate-semialdehyde dehydrogenase; Similar to GB:AE000657 percent identity: 69.47; identified by sequence similarity; putative; Belongs to the aspartate-semialdehyde dehydrogenase family.
