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.

mspAPorin; The major porin in this organism, forms a water-filled channel which favors the permeation of cations, amino acids, iron Fe(3+) and less efficiently phosphate. Does not transport Fe-ExoMS, the predominant siderophore. Plays a role in transport of beta-lactamase and hydrophilic fluoroquinolone antibiotics such as norfloxacin as well as chloramphenicol. There are about 2400 porins in wild-type, 800 in an mspA deletion and 150 in a double mspA-mspC deletion. Different conductance values with maxima at 2.3 and 4.6 nanosiemens might be caused by a simultaneous reconstitution of MspA [...] (211 aa)    
Predicted Functional Partners:
ABK73124.1
Serine esterase, cutinase family protein; Identified by match to protein family HMM PF01083.
      
 0.507
ABK72746.1
Cutinase; Catalyzes the hydrolysis of cutin, a polyester that forms the structure of plant cuticle.
      
 0.507
lfrA
Proton antiporter efflux pump; Energy-dependent efflux pump that contributes to drug resistance. Catalyzes the efflux of norfloxacin and several related fluoroquinolones (FQ). Contributes significantly to the intrinsic MICs for ethidium bromide and acriflavine. Overexpression confers low-level resistance to hydrophilic FQ such as ciprofloxacin, ofloxacin and levofloxacin, and to ethidium bromide, acridine, acriflavine, rhodamine 123 and some quaternary ammonium compounds. May contribute to resistance to certain beta-lactams. Probably uses the proton motive force.

mscL
Large conductance mechanosensitive channel protein; Channel that opens in response to stretch forces in the membrane lipid bilayer. May participate in the regulation of osmotic pressure changes within the cell.
