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

ECA3631Ham1 protein homolog; Pyrophosphatase that catalyzes the hydrolysis of nucleoside triphosphates to their monophosphate derivatives, with a high preference for the non-canonical purine nucleotides XTP (xanthosine triphosphate), dITP (deoxyinosine triphosphate) and ITP. Seems to function as a house-cleaning enzyme that removes non-canonical purine nucleotides from the nucleotide pool, thus preventing their incorporation into DNA/RNA and avoiding chromosomal lesions. Belongs to the HAM1 NTPase family. (197 aa)    
Predicted Functional Partners:
guaA
GMP synthase [glutamine-hydrolyzing]; Catalyzes the synthesis of GMP from XMP.
 
 
 0.972
rph
Ribonuclease PH; Phosphorolytic 3'-5' exoribonuclease that plays an important role in tRNA 3'-end maturation. Removes nucleotide residues following the 3'-CCA terminus of tRNAs; can also add nucleotides to the ends of RNA molecules by using nucleoside diphosphates as substrates, but this may not be physiologically important. Probably plays a role in initiation of 16S rRNA degradation (leading to ribosome degradation) during starvation.
 
    0.960
guaB
Inosine-5'-monophosphate dehydrogenase; Catalyzes the conversion of inosine 5'-phosphate (IMP) to xanthosine 5'-phosphate (XMP), the first committed and rate-limiting step in the de novo synthesis of guanine nucleotides, and therefore plays an important role in the regulation of cell growth. Belongs to the IMPDH/GMPR family.
 
 0.935
ndk
Nucleoside diphosphate kinase; Major role in the synthesis of nucleoside triphosphates other than ATP. The ATP gamma phosphate is transferred to the NDP beta phosphate via a ping-pong mechanism, using a phosphorylated active-site intermediate; Belongs to the NDK family.
  
 0.934
gpt
Xanthine-guanine phosphoribosyltransferase; Acts on guanine, xanthine and to a lesser extent hypoxanthine; Belongs to the purine/pyrimidine phosphoribosyltransferase family. XGPT subfamily.

ECA3005
Similar to Ralstonia solanacearum putative glutamine amidotransferase protein rsc0213 or rs00645 SWALL:Q8Y2W9 (EMBL:AL646058) (238 aa) fasta scores: E(): 9e-37, 45.37% id in 238 aa, and to Xylella fastidiosa GMP synthase xf0560 SWALL:Q9PFU7 (EMBL:AE003903) (240 aa) fasta scores: E(): 1.1e-28, 43.8% id in 242 aa.
  
 
 0.910
ECA3632
Putative oxygen-independent coproporphyrinogen III oxidase; Probably acts as a heme chaperone, transferring heme to an unknown acceptor. Binds one molecule of heme per monomer, possibly covalently. Binds 1 [4Fe-4S] cluster. The cluster is coordinated with 3 cysteines and an exchangeable S-adenosyl-L-methionine. Belongs to the anaerobic coproporphyrinogen-III oxidase family.
    0.910
hpt
Similar to Salmonella typhimurium hypoxanthine phosphoribosyltransferase Hpt or stm0170 SWALL:HPRT_SALTY (SWALL:O33799) (178 aa) fasta scores: E(): 1.2e-54, 86.2% id in 174 aa, and to Escherichia coli, Escherichia coli O6, and Shigella flexneri hypoxanthine phosphoribosyltransferase Hpt or b0125 or c0154 or sf0122 SWALL:HPRT_ECOLI (SWALL:P36766) (178 aa) fasta scores: E(): 2.4e-54, 84.48% id in 174 aa; Belongs to the purine/pyrimidine phosphoribosyltransferase family.
  
 
 0.909
murI
Glutamate racemase; Provides the (R)-glutamate required for cell wall biosynthesis.
 
    0.905
ushA
Similar to Escherichia coli protein UshA precursor [includes: UDP-sugar hydrolase and 5'-nucleotidase] UshA or b0480 SWALL:USHA_ECOLI (SWALL:P07024) (550 aa) fasta scores: E(): 1.6e-157, 71.5% id in 551 aa; Belongs to the 5'-nucleotidase family.
