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.

cddCytidine deaminase (cdd); This enzyme scavenges exogenous and endogenous cytidine and 2'-deoxycytidine for UMP synthesis. (292 aa)    
Predicted Functional Partners:
udp
Uridine phosphorylase (udp); Catalyzes the reversible phosphorylytic cleavage of uridine and deoxyuridine to uracil and ribose- or deoxyribose-1-phosphate. The produced molecules are then utilized as carbon and energy sources or in the rescue of pyrimidine bases for nucleotide synthesis (By similarity).
  
 
 0.989
tdk
Thymidine kinase (tdk); Similar to SP:P23331 GB:X51523 GB:X53733 GB:X67326 PID:43047 percent identity: 68.62; identified by sequence similarity; putative.
 
  
 0.973
udk
Uridine kinase (udk); Similar to SP:P31218 GB:X71492 PID:296947 GB:U00096 PID:1736770 percent identity: 67.82; identified by sequence similarity; putative.
    
 0.972
HI_0206
5'-nucleotidase, putative; Degrades NAD into adenosine and nicotinamide riboside, the latter being subsequently internalized by a specific permease. Also endowed with NAD(P) pyrophosphatase activity. Exhibits a broad substrate specificity, recognizing either mono- or dinucleotide nicotinamides and different adenosine phosphates with a maximal activity on 5'-adenosine monophosphate; Belongs to the 5'-nucleotidase family.
    
  0.934
surE
Stationary-phase survival protein (surE); Nucleotidase that shows phosphatase activity on nucleoside 5'-monophosphates; Belongs to the SurE nucleotidase family.
  
  
  0.933
cpdB
2',3'-cyclic-nucleotide 2'-phosphodiesterase (cpdB); This bifunctional enzyme catalyzes two consecutive reactions during ribonucleic acid degradation. Converts a 2',3'-cyclic nucleotide to a 3'-nucleotide and then the 3'-nucleotide to the corresponding nucleoside and phosphate (By similarity).
 
  
  0.931
deoC
Deoxyribose-phosphate aldolase (deoC); Catalyzes a reversible aldol reaction between acetaldehyde and D-glyceraldehyde 3-phosphate to generate 2-deoxy-D-ribose 5- phosphate; Belongs to the DeoC/FbaB aldolase family. DeoC type 1 subfamily.
  
 
 0.723
HI_1582
Conserved hypothetical protein; Similar to PID:1204257 SP:P52008 GB:U00096 PID:1788183 percent identity: 40.56; identified by sequence similarity; putative; To E.coli YecM.
  
     0.566
seqA
seqA protein (seqA); Negative regulator of replication initiation, which contributes to regulation of DNA replication and ensures that replication initiation occurs exactly once per chromosome per cell cycle. Binds to pairs of hemimethylated GATC sequences in the oriC region, thus preventing assembly of replication proteins and re- initiation at newly replicated origins. Repression is relieved when the region becomes fully methylated.
  
   
 0.532
gapA
Glyceraldehyde-3-phosphate dehydrogenase (gapdH); Catalyzes the oxidative phosphorylation of glyceraldehyde 3- phosphate (G3P) to 1,3-bisphosphoglycerate (BPG) using the cofactor NAD. The first reaction step involves the formation of a hemiacetal intermediate between G3P and a cysteine residue, and this hemiacetal intermediate is then oxidized to a thioester, with concomitant reduction of NAD to NADH. The reduced NADH is then exchanged with the second NAD, and the thioester is attacked by a nucleophilic inorganic phosphate to produce BPG.
