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:
nadAQuinolinate synthetase, A protein; Catalyzes the condensation of iminoaspartate with dihydroxyacetone phosphate to form quinolinate. (347 aa)
pnuCNMN family, nucleoside/purine/pyrimidine transporter; Required for nicotinamide riboside transport across the inner membrane. (239 aa)
pncANicotinamidase/ pyrazinamidase; Similar to E. coli orf, hypothetical protein (AAC74838.1); Blastp hit to AAC74838.1 (219 aa), 80% identity in aa 7 - 219. (218 aa)
nadBQuinolinate synthetase, B protein; Catalyzes the oxidation of L-aspartate to iminoaspartate. (540 aa)
serBSimilar to E. coli 3-phosphoserine phosphatase (AAC77341.1); Blastp hit to AAC77341.1 (322 aa), 93% identity in aa 1 - 322. (322 aa)
nadRTrifunctional protein; This enzyme has three activities: DNA binding, nicotinamide mononucleotide (NMN) adenylyltransferase and ribosylnicotinamide (RN) kinase. The DNA-binding domain binds to the nadB operator sequence in an NAD- and ATP-dependent manner. As NAD levels increase within the cell, the affinity of NadR for the nadB operator regions of nadA, nadB, and pncB increases, repressing the transcription of these genes. The RN kinase activity catalyzes the phosphorylation of RN to form nicotinamide ribonucleotide. The NMN adenylyltransferase activity catalyzes the transfer of the A [...] (410 aa)
trpRTranscriptional repressor for trp operon and aroH; This protein is an aporepressor. When complexed with L- tryptophan it binds the operator region of the trp operon (5'- ACTAGT-'3') and prevents the initiation of transcription. The complex also regulates trp repressor biosynthesis by binding to its regulatory region (By similarity). (108 aa)
