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:
nadRTrifunctional NAD biosynthesis/regulator protein NadR; 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 [...] (410 aa)
lldDL-lactate dehydrogenase, FMN-linked; Catalyzes the conversion of L-lactate to pyruvate. Seems to be a primary dehydrogenase in the respiratory chain. To a lesser extent, can also oxidize DL-alpha-hydroxybutyrate, but not D-lactate. (396 aa)
lldRDual role activator/repressor for lldPRD operon; May be a regulatory protein for the LCT genes. (258 aa)
lldPL-lactate permease; Transports L-lactate across the membrane. Can also transport D-lactate and glycolate. Seems to be driven by a proton motive force. (551 aa)
rpoARNA polymerase, alpha subunit; DNA-dependent RNA polymerase (RNAP) catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. This subunit plays an important role in subunit assembly since its dimerization is the first step in the sequential assembly of subunits to form the holoenzyme. (329 aa)
arcBAerobic respiration control sensor protein ArcB; Member of the two-component regulatory system ArcB/ArcA. Sensor-regulator protein for anaerobic repression of the arc modulon. Activates ArcA via a four-step phosphorelay. ArcB can also dephosphorylate ArcA by a reverse phosphorelay involving His-717 and Asp-576. (778 aa)
glcAGlycolate transporter; Transports glycolate across the membrane. Can also transport L-lactate and D-lactate. Seems to be driven by a proton motive force. (560 aa)
sxyCRP-S-dependent promoter expression factor; Induces low levels of natural DNA uptake by inducing transcription of the competence genes (the CRP-S regulon) required for DNA transformation. Induction of the CRP-S regulon also requires Sxy- activated promoter (CRP-S), cAMP receptor protein (CRP) and cAMP. Induces CRP-S site-containing genes which are involved in genome maintenance and transcription or encoding transposases and toxin-antitoxin pairs. (209 aa)
pnuCNicotinamide riboside transporter; Required for nicotinamide riboside transport across the inner membrane. (239 aa)
