STRING protein interaction network
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 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
protein homology
Your Input:
Gene Fusion
ahrCTranscriptional regulator of arginine metabolism; Represses the synthesis of biosynthetic enzymes and activates the arginine catabolism. Controls the transcription of the two operons rocABC and rocDEF (149 aa)    
Predicted Functional Partners:
Ornithine carbamoyltransferase; Reversibly catalyzes the transfer of the carbamoyl group from carbamoyl phosphate (CP) to the N(epsilon) atom of ornithine (ORN) to produce L-citrulline
N-acetylglutamate gamma-semialdehyde dehydrogenase; Catalyzes the NADPH-dependent reduction of N-acetyl-5- glutamyl phosphate to yield N-acetyl-L-glutamate 5-semialdehyde
Belongs to the argininosuccinate synthase family. Type 1 subfamily
Bira family transcriptional regulator, biotin operon repressor / biotin---[acetyl-coa-carboxylase] ligase; Acts both as a biotin--[acetyl-CoA-carboxylase] ligase and a repressor
N-acetylglutamate 5-phosphotransferase (acetylglutamate kinase); Catalyzes the ATP-dependent phosphorylation of N-acetyl-L- glutamate
Glutamate n-acetyltransferase / amino-acid n-acetyltransferase; Catalyzes two activities which are involved in the cyclic version of arginine biosynthesis: the synthesis of N-acetylglutamate from glutamate and acetyl-CoA as the acetyl donor, and of ornithine by transacetylation between N(2)-acetylornithine and glutamate
Factor for double strand breaks dna repair and genetic recombination; Involved in recombinational repair of damaged DNA. Seems to be the first protein recruited to repair centers, foci that are the site of double-strand DNA break(s), followed by RecO and then RecF
Negatively regulates transcription of bacterial ribonucleotide reductase nrd genes and operons by binding to NrdR- boxes
Argininosuccinate lyase; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme
Represses dinA, dinB, dinC, recA genes and itself by binding to the 14 bp palindromic sequence 5'-CGAACNNNNGTTCG-3'; some genes have a tandem consensus sequence and their binding is cooperative . In the presence of single-stranded DNA, RecA interacts with LexA causing an autocatalytic cleavage which disrupts the DNA-binding part of LexA, leading to derepression of the SOS regulon and eventually DNA repair; autocleavage is maximal at pH 11 in the absence of RecA and ssDNA
