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
Your Input:
xdhAXanthine dehydrogenase, molybdenum binding subunit; Presumed to be a dehydrogenase, but possibly an oxidase. Participates in limited purine salvage (requires aspartate) but does not support aerobic growth on purines as the sole carbon source (purine catabolism). Deletion results in increased adenine sensitivity, suggesting that this protein contributes to the conversion of adenine to guanine nucleotides during purine salvage. (752 aa)
addAdenosine deaminase; Protein involved in nucleobase, nucleoside and nucleotide interconversion; Belongs to the metallo-dependent hydrolases superfamily. Adenosine and AMP deaminases family. Adenosine deaminase subfamily. (333 aa)
hptHypoxanthine phosphoribosyltransferase; Acts preferentially on hypoxanthine; has very low activity towards guanine. Inactive towards xanthine. Belongs to the purine/pyrimidine phosphoribosyltransferase family. (178 aa)
aptAdenine phosphoribosyltransferase; Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis. (183 aa)
allAUreidoglycolate lyase, releasing urea; Catalyzes the catabolism of the allantoin degradation intermediate (S)-ureidoglycolate, generating urea and glyoxylate. Involved in the anaerobic utilization of allantoin as sole nitrogen source. Reinforces the induction of genes involved in the degradation of allantoin and glyoxylate by producing glyoxylate. (160 aa)
allBAllantoinase; Catalyzes the conversion of allantoin (5-ureidohydantoin) to allantoic acid by hydrolytic cleavage of the five-member hydantoin ring; Belongs to the metallo-dependent hydrolases superfamily. Allantoinase family. (453 aa)
ybbWPutative allantoin transporter; Transport of allantoin. (484 aa)
hiuHHydroxyisourate hydrolase; Catalyzes the hydrolysis of 5-hydroxyisourate (HIU) to 2-oxo- 4-hydroxy-4-carboxy-5-ureidoimidazoline (OHCU). (137 aa)
allCAllantoate amidohydrolase; Involved in the anaerobic nitrogen utilization via the assimilation of allantoin. Catalyzes specifically the hydrolysis of allantoate to yield CO2, NH3 and S- ureidoglycine, which is unstable and readily undergoes a second deamination by S-ureidoglycine aminohydrolase AllE to yield S- ureidoglycolate and NH3. In vivo, the spontaneous release of S-ureidoglycolate and ammonia from S-ureidoglycine appears to be too slow to sustain an efficient flux of nitrogen. (411 aa)
rihCRibonucleoside hydrolase 3; Hydrolyzes both purine and pyrimidine ribonucleosides with a broad-substrate specificity with decreasing activity in the order uridine, xanthosine, inosine, adenosine, cytidine, guanosine. (304 aa)
allES-ureidoglycine aminohydrolase; Involved in the anaerobic nitrogen utilization via the assimilation of allantoin. Catalyzes the second stereospecific hydrolysis reaction (deamination) of the allantoin degradation pathway, producing S-ureidoglycolate and ammonia from S-ureidoglycine. Belongs to the UGHY family. (261 aa)
purFAmidophosphoribosyltransferase; Catalyzes the formation of phosphoribosylamine from phosphoribosylpyrophosphate (PRPP) and glutamine. Can also use NH(3) in place of glutamine. (505 aa)
purMPhosphoribosylaminoimidazole synthetase = AIR synthetase; Protein involved in purine nucleotide biosynthetic process; Belongs to the AIR synthase family. (345 aa)
allDUreidoglycolate dehydrogenase; AllD plays a pivotal role as a metabolic branch-point enzyme in nitrogen utilization via the assimilation of allantoin. It is able to utilize allantoin as a sole source of nitrogen under anaerobic conditions. Catalyzes the oxidation of ureidoglycolate to oxalurate. (349 aa)
purDPhosphoribosylglycinamide synthetase = GAR synthetase; Protein involved in purine nucleotide biosynthetic process; Belongs to the GARS family. (429 aa)
adeDCryptic adenine deaminase; Protein involved in metabolic process; Belongs to the metallo-dependent hydrolases superfamily. Adenine deaminase family. (588 aa)
guaDGuanine deaminase; Catalyzes the hydrolytic deamination of guanine, producing xanthine and ammonia; Belongs to the metallo-dependent hydrolases superfamily. ATZ/TRZ family. (439 aa)
xdhDPutative hypoxanthine oxidase, molybdopterin-binding/Fe-S binding; Probably has no xanthine dehydrogenase activity; however deletion results in increased adenine sensitivity, suggesting that this protein contributes to the conversion of adenine to guanine nucleotides during purine salvage. (956 aa)
xdhCXanthine dehydrogenase, Fe-S binding subunit; Iron-sulfur subunit of the xanthine dehydrogenase complex. (159 aa)
xdhBXanthine dehydrogenase, FAD-binding subunit; Presumed to be a dehydrogenase, but possibly an oxidase. Participates in limited purine salvage (requires aspartate) but does not support aerobic growth on purines as the sole carbon source (purine catabolism). (292 aa)
