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

macAMacrolide transporter membrane fusion protein (MFP) component; Part of the tripartite efflux system MacAB-TolC. MacA stimulates the ATPase activity of MacB by promoting the closed ATP- bound state of MacB, increases the capacity of MacB to bind macrolides such as erythromycin, and provides a physical link between MacB and TolC. When overexpressed, the system confers resistance against macrolides composed of 14- and 15-membered lactones but no or weak resistance against 16-membered ones. In addition, MacA binds tightly rough-core lipopolysaccharide (R-LPS), suggesting that the system co [...] (371 aa)    
Predicted Functional Partners:
macB
Macrolide ABC transporter peremase/ATPase; Part of the tripartite efflux system MacAB-TolC. MacB is a non-canonical ABC transporter that contains transmembrane domains (TMD), which form a pore in the inner membrane, and an ATP-binding domain (NBD), which is responsible for energy generation. When overexpressed, the system confers resistance against macrolides composed of 14- and 15-membered lactones but no or weak resistance against 16-membered ones. In addition, the system could also transport R-LPS or a similar glycolipid. Belongs to the ABC transporter superfamily. Macrolide exporte [...]

tolC
Transport channel; Outer membrane channel, which is required for the function of several efflux systems such as AcrAB-TolC, AcrEF-TolC, EmrAB-TolC and MacAB-TolC. These systems are involved in export of antibiotics and other toxic compounds from the cell. TolC is also involved in import of colicin E1 into the cells.
  
 0.999
emrA
Multidrug efflux system; Part of the tripartite efflux system EmrAB-TolC, which confers resistance to antibiotics such as CCCP, FCCP, 2,4-dinitrophenol and nalidixic acid. EmrA is a drug-binding protein that provides a physical link between EmrB and TolC; Belongs to the membrane fusion protein (MFP) (TC 8.A.1) family.
 
 
 0.957
acrD
Aminoglycoside/multidrug efflux system; Participates in the efflux of aminoglycosides. Confers resistance to a variety of these substances. Belongs to the resistance-nodulation-cell division (RND) (TC 2.A.6) family.
 0.950
acrF
Multidrug efflux system protein; Part of the tripartite efflux system AcrEF-TolC. Involved in the efflux of indole and organic solvents. Belongs to the resistance-nodulation-cell division (RND) (TC 2.A.6) family.
 0.949
acrB
Multidrug efflux system protein; AcrA-AcrB-AcrZ-TolC is a drug efflux protein complex with broad substrate specificity that uses the proton motive force to export substrates.
 0.910
emrB
Multidrug efflux system protein; Part of the tripartite efflux system EmrAB-TolC, which confers resistance to antibiotics such as CCCP, FCCP, 2,4-dinitrophenol and nalidixic acid.

emrK
Multidrug resistance efflux pump membrane fusion protein; Part of the tripartite efflux system EmrYK-TolC, which confers resistance to various drugs.
 
 
 0.837
mdtB
Multidrug efflux system, subunit B; The MdtABC tripartite complex confers resistance against novobiocin and deoxycholate. MdtABC requires TolC for its function.
 
 0.830
mdtC
Multidrug efflux system, subunit C; The MdtABC tripartite complex confers resistance against novobiocin and deoxycholate. MdtABC requires TolC for its function.
