STRINGSTRING
STRING protein interaction network
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

azo1653Putative Autotransporter,30% identity to TrEMBL;Q87UU2. Weak homology with hits in the DB. Signal Peptide present. No TMH reported present. Has PF03797;Autotransporter beta-domain;The protein component that mediates secretion through the outer membrane is contained within the secreted protein itself, hence the proteins secreted in this way are called autotransporters. This family corresponds to the presumed integral membrane beta-barrel domain that transports the protein. This domain is found at the C terminus of the proteins it occurs in. The N terminus contains the variable passenger [...] (902 aa)    
Predicted Functional Partners:
fhuF
Putative TonB-dependent receptor; Ferrioxamine B receptor precursor, FhuF. Iron-regulated outer membrane protein that bind and uptake ferrioxamine in association with the TonB protein. Involved in the reduction of ferric iron in cytoplasmic ferrioxamine B. Binds 1 2Fe-2S cluster. In e.coli the fhuF gene reacts very sensitive to minor changes of Fe2+ and Fur(Ferric uptake regulator). SWISSPROT: FOXA_SALTY. Prim. accession #:Q56145 EMBL: AE008712; AAL19318.1; AF060876; AAC15464.1; U62282; AAB04552.1; InterPro:IPR000531; TonB_boxC. Pfam: PF00593; TonB_dep_Rec; 1. PROSITE: PS00430; TONB_DE [...]

fhuA1
In E.coli this receptor binds the ferrichrome-iron ligand. It interacts with the tonB protein, which is responsible for energy coupling of the ferrichrome-promoted iron transport system. Acts as a receptor for bacteriophage T5 as well as T1, phi80 and colicin M. Binding of T5 triggers the opening of a high conductance ion channel. Can also transport the antibiotic albomycin. Signal peptide; Specificity unclear.

azo0378
Putative TonB-dependent receptor. Homology to bpp0186 ao B. parapertussis of 54% (trembl|Q7W206) The TonB protein interacts with outer membrane receptor proteins that carry out high-affinity binding and energy-dependent uptake of specific substrates into the periplasmic space. These substrates are either poorly permeable through the porin channels or are encountered at very low concentrations. In the absence of TonB these receptors bind their substrates but do not carry out active transport.
