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:
some 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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

rutFFMN reductase (NADH) RutF; Catalyzes the reduction of FMN to FMNH2 which is used to reduce pyrimidine by RutA via the Rut pathway. In vitro, the flavin reductase Fre can substitute for the function of RutF, however, RutF is required for uracil utilization in vivo (164 aa)    
Predicted Functional Partners:
rutB
Peroxyureidoacrylate/ureidoacrylate amidohydrolase RutB; In vivo, quickly hydrolyzes the ureidoacrylate peracid to avoid toxicity, but can also hydrolyzes ureidoacrylate that is formed spontaneously from ureidoacrylate peracid. One of the products of hydrolysis, carbamate, hydrolyzes spontaneously, thereby releasing one of the pyrimidine rings nitrogen atoms as ammonia and one of its carbons as CO2
 
 
 0.998
rutA
Pyrimidine monooxygenase RutA; Catalyzes the pyrimidine ring opening between N-3 and C- 4 by an unusual flavin hydroperoxide-catalyzed mechanism to yield ureidoacrylate peracid. It cleaves pyrmidine rings directly by adding oxygen atoms, making a toxic ureidoacrylate peracid product which can be spontaneously reduced to ureidoacrylate. Requires the flavin reductase RutF to regenerate FMN in vivo. RutF can be substituted by Fre in vitro; Belongs to the NtaA/SnaA/SoxA(DszA) monooxygenase family. RutA subfamily
 
 
 0.998
rutD
Putative aminoacrylate hydrolase RutD; May increase the rate of spontaneous hydrolysis of aminoacrylate to malonic semialdehyde. Required to remove a toxic intermediate produce in vivo, but not in vitro in the pyrimidine nitrogen degradation
 
  
 0.990
rutC
Putative aminoacrylate peracid reductase RutC; May reduce aminoacrylate peracid to aminoacrylate. Required to remove a toxic intermediate produce in vivo, but not in vitro in the pyrimidine nitrogen degradation
 
  
 0.987
rutE
Probable malonic semialdehyde reductase RutE; May reduce toxic product malonic semialdehyde to 3- hydroxypropionic acid, which is excreted. RutE is apparently supplemented by YdfG. Required in vivo, but not in vitro in pyrimidine nitrogen degradation; Belongs to the nitroreductase family. HadB/RutE subfamily
 
  
 0.969
rutG
Putative pyrimidine permease RutG; May function as a proton-driven pyrimidine uptake system
 
  
 0.942
preA
NAD-dependent dihydropyrimidine dehydrogenase subunit PreA; Involved in pyrimidine base degradation. Catalyzes physiologically the reduction of uracil to 5,6-dihydrouracil (DHU) by using NADH as a specific cosubstrate. It also catalyzes the reverse reaction and the reduction of thymine to 5,6- dihydrothymine (DHT)
    
  0.920
codA
Cytosine deaminase; Catalyzes the hydrolytic deamination of cytosine to uracil. Is involved in the pyrimidine salvage pathway, which allows the cell to utilize cytosine for pyrimidine nucleotide synthesis. Is also able to catalyze deamination of isoguanine, a mutagenic oxidation product of adenine in DNA, and of isocytosine. To a lesser extent, also catalyzes the conversion of 5- fluorocytosine (5FC) to 5-fluorouracil (5FU); this activity allows the formation of a cytotoxic chemotherapeutic agent from a non- cytotoxic precursor; Belongs to the metallo-dependent hydrolases superfamily.

yaiE
Pyrimidine/purine nucleoside phosphorylase; Catalyzes the phosphorolysis of diverse nucleosides, yielding D-ribose 1-phosphate and the respective free bases. Can use uridine, adenosine, guanosine, cytidine, thymidine, inosine and xanthosine as substrates. Also catalyzes the reverse reactions. Is not able to produce D-ribose 1-phosphate from D- ribose and phosphate; Belongs to the nucleoside phosphorylase PpnP family

preT
NAD-dependent dihydropyrimidine dehydrogenase subunit PreT; Involved in pyrimidine base degradation. Catalyzes physiologically the reduction of uracil to 5,6-dihydrouracil (DHU) by using NADH as a specific cosubstrate. It also catalyzes the reverse reaction and the reduction of thymine to 5,6- dihydrothymine (DHT)
