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:
a 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
argJProbable glutamate N-acetyltransferase ArgJ; 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. (404 aa)    
Predicted Functional Partners:
Probable N-acetyl-gamma-glutamyl-phoshate reductase ArgC; Catalyzes the NADPH-dependent reduction of N-acetyl-5- glutamyl phosphate to yield N-acetyl-L-glutamate 5-semialdehyde.
Probable acetylglutamate kinase ArgB; Catalyzes the ATP-dependent phosphorylation of N-acetyl-L- glutamate.
Rv1655, (MTCY06H11.20), len: 400 aa. Probable argD,Acetylornithine aminotransferase, similar to ARGD_ECOLI|P18335 (406 aa), FASTA scores: opt: 958, E(): 0,(38.6% identity in 404 aa overlap), contains PS00600 Aminotransferases class-III pyridoxal-phosphate attachment site. Belongs to class-III of pyridoxal-phosphate-dependent aminotransferases.
Probable ornithine carbamoyltransferase, anabolic ArgF; Reversibly catalyzes the transfer of the carbamoyl group from carbamoyl phosphate (CP) to the N(epsilon) atom of ornithine (ORN) to produce L-citrulline, which is a substrate for argininosuccinate synthetase, the enzyme involved in the final step in arginine biosynthesis; Belongs to the aspartate/ornithine carbamoyltransferase superfamily. OTCase family.
Probable arginine repressor ArgR (AHRC); Regulates arginine biosynthesis genes.
Rv1658, (MTCY06H11.23), len: 398 aa. Probable argG,Argininosuccinate synthase, similar to ASSY_STRCL|P50986 argininosuccinate synthase from Streptomyces clavuligerus (397 aa), FASTA scores: opt: 1873, E(): 0, (67.8% identity in 397 aa overlap); contains PS00564 Argininosuccinate synthase signature 1, PS00565 Argininosuccinate synthase signature 2. Belongs to the argininosuccinate synthase family.
Rv1659, (MTCY06H11.24), len: 470 aa. Probable argH,Argininosuccinate lyase, similar to ARLY_ECOLI|P11447 argininosuccinate lyase from Escherichia coli (457 aa),FASTA scores: opt: 1091, E(): 0, (42.5% identity in 461 aa overlap); contains PS00017 ATP/GTP-binding site motif A,PS00163 Fumarate lyases signature. Belongs to the lyase 1 family. Argininosuccinate lyase subfamily.
Probable L-glutamate alpha-N-acetyltranferase ArgA (alpha-N-acetylglutamate synthase); Catalyzes the conversion of L-glutamate to alpha-N-acetyl-L- glutamate. L-glutamine is a significantly better substrate compared to L-glutamate; Belongs to the acetyltransferase family.
GCN5-related N-acetyltransferase; Rv0428c, (MTCY22G10.25c), len: 302 aa. Probable acetyltransferase. Contains GNAT (Gcn5-related N-acetyltransferase) domain in C-terminal part. See Vetting et al. 2005.
Rv0337c, (MTCY279.04c), len: 429 aa. Probable aspC,aspartate aminotransferase (transaminase A), equivalent to CAC32019.1|AL583925 probable aspartate aminotransferase from Mycobacterium leprae (437 aa). Also highly similar to many e.g. Q48143|U32823 aspartate aminotransferase (404 aa), FASTA scores: opt: 1646, E(): 0, (57.2% identity in 404 aa overlap).
