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:
btuBOuter membrane receptor for transport of vitamin B12, E colicins, and bacteriophage BF23; 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; Belongs to the TonB-dependent receptor family. BtuB (TC 1.B.14.3.1) subfamily. (614 aa)
btuDVitamin B12 transport protein; Part of the ABC transporter complex BtuCDF involved in vitamin B12 import. Responsible for energy coupling to the transport system. (249 aa)
hemAGlutamyl tRNA reductase; Catalyzes the NADPH-dependent reduction of glutamyl-tRNA(Glu) to glutamate 1-semialdehyde (GSA). (418 aa)
cbiKSynthesis of vitamin B12 adenosyl cobalamide precursor; Catalyzes the insertion of Co(2+) into sirohydrochlorin as part of the anaerobic pathway to cobalamin biosynthesis; Belongs to the CbiK family. (264 aa)
idiIsopentenyldiphosphate isomerase; Catalyzes the 1,3-allylic rearrangement of the homoallylic substrate isopentenyl (IPP) to its highly electrophilic allylic isomer, dimethylallyl diphosphate (DMAPP). (181 aa)
cysGSiroheme synthase; Multifunctional enzyme that catalyzes the SAM-dependent methylations of uroporphyrinogen III at position C-2 and C-7 to form precorrin-2 via precorrin-1. Then it catalyzes the NAD-dependent ring dehydrogenation of precorrin-2 to yield sirohydrochlorin. Finally, it catalyzes the ferrochelation of sirohydrochlorin to yield siroheme. In the N-terminal section; belongs to the precorrin-2 dehydrogenase / sirohydrochlorin ferrochelatase family. (457 aa)
hemDUroporphyrinogen III synthase; Catalyzes cyclization of the linear tetrapyrrole, hydroxymethylbilane, to the macrocyclic uroporphyrinogen III. Belongs to the uroporphyrinogen-III synthase family. (246 aa)
pocRPropanediol utilization protein; Positive regulatory protein of pdu and cob operons. (303 aa)
yjeBPutative negative regulator; Nitric oxide-sensitive repressor of genes involved in protecting the cell against nitrosative stress. May require iron for activity. Represses hmp expression under conditions of elevated intracellular iron concentrations, in the absence of nitric oxide. (141 aa)
hemCPorphobilinogen deaminase; Tetrapolymerization of the monopyrrole PBG into the hydroxymethylbilane pre-uroporphyrinogen in several discrete steps. Belongs to the HMBS family. (318 aa)
crpCatabolite activator protein (CAP); A global transcription regulator. Complexes with cyclic AMP (cAMP) which allosterically activates DNA binding to regulate transcription. It can act as an activator, repressor, coactivator or corepressor. Induces a severe bend in DNA. Acts as a negative regulator of its own synthesis as well as for adenylate cyclase (cyaA), which generates cAMP. Plays a major role in carbon catabolite repression (CCR) (By similarity). (210 aa)
hemHFerrochelatase; Catalyzes the ferrous insertion into protoporphyrin IX. (320 aa)
hemBSimilar to E. coli 5-aminolevulinate dehydratase = porphobilinogen synthase (AAC73472.1); Blastp hit to AAC73472.1 (335 aa), 93% identity in aa 12 - 335; Belongs to the ALAD family. (324 aa)
hemLGlutamate-1-semialdehyde 2,1-aminomutase. (SW:GSA_SALTY). (426 aa)
