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:
araCAra regulon transcriptional activator; Transcription factor that regulates the expression of several genes involved in the transport and metabolism of L-arabinose. Functions both as a positive and a negative regulator. In the presence of arabinose, activates the expression of the araBAD, araE, araFGH and araJ promoters. In the absence of arabinose, negatively regulates the araBAD operon. Represses its own transcription. Acts by binding directly to DNA. (292 aa)
btuFVitamin B12 ABC transporter periplasmic binding protein; Part of the ABC transporter complex BtuCDF involved in vitamin B12 import. Binds vitamin B12 and delivers it to the periplasmic surface of BtuC. (266 aa)
lacILactose-inducible lac operon transcriptional repressor; Repressor of the lactose operon. Binds allolactose as an inducer. (360 aa)
btuDVitamin B12 ABC transporter ATPase; Part of the ABC transporter complex BtuCDF involved in vitamin B12 import. Responsible for energy coupling to the transport system. (249 aa)
btuEGlutathione peroxidase; Non-specific peroxidase that can use thioredoxin or glutathione as a reducing agent. In vitro, utilizes preferentially thioredoxin A to decompose hydrogen peroxide as well as cumene-, tert- butyl-, and linoleic acid hydroperoxides, suggesting that it may have one or more organic hydroperoxide as its physiological substrate. Belongs to the glutathione peroxidase family. BtuE subfamily. (183 aa)
btuCVitamin B12 ABC transporter permease; Part of the ABC transporter complex BtuCDF involved in vitamin B12 import. Involved in the translocation of the substrate across the membrane; Belongs to the binding-protein-dependent transport system permease family. FecCD subfamily. (326 aa)
eutREut operon transcriptional activator, AraC family; Activates the transcription of the eut operon. Also positively regulates its own transcription. Probably binds ethanolamine and vitamin B12 as effectors (By similarity). (350 aa)
eutSPutative ethanol utilization carboxysome structural protein; May be involved in the formation of a specific microcompartment in the cell in which the metabolism of potentially toxic by-products takes place; Belongs to the EutS/PduU family. (111 aa)
exbDMembrane spanning protein in TonB-ExbB-ExbD complex; Involved in the TonB-dependent energy-dependent transport of various receptor-bound substrates. (141 aa)
exbBMembrane spanning protein in TonB-ExbB-ExbD complex; Involved in the TonB-dependent energy-dependent transport of various receptor-bound substrates. Protects ExbD from proteolytic degradation and functionally stabilizes TonB. (244 aa)
btuBVitamin B12/cobalamin outer membrane transporter; Involved in the active translocation of vitamin B12 (cyanocobalamin) across the outer membrane to the periplasmic space. It derives its energy for transport by interacting with the trans- periplasmic membrane protein TonB. Is also a receptor for bacteriophages BF23 and C1, and for A and E colicins. (614 aa)
