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:
some 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

algIMboat, membrane-bound o-acyltransferase family protein; Together with AlgJ and AlgF, forms an inner membrane complex which probably interacts with the alginate polymerization-transport complex and adds acetyl groups at the O-2 and O-3 positions of mannuronate residues. Acetylation of alginate is important for the architecture of biofilms and increases resistance to opsonic killing in the host (520 aa)    
Predicted Functional Partners:
algJ
Alginate o-acetyltransferase complex protein algj; Together with AlgI and AlgF, forms an inner membrane complex which probably interacts with the alginate polymerization-transport complex and adds acetyl groups at the O-2 and O-3 positions of mannuronate residues. Acetylation of alginate is important for the architecture of biofilms and increases resistance to opsonic killing in the host

algF
Alginate o-acetyl transferase algf family protein; Together with AlgI and AlgJ, forms an inner membrane complex which probably interacts with the alginate polymerization-transport complex and adds acetyl groups at the O-2 and O-3 positions of mannuronate residues. Acetylation of alginate is important for the architecture of biofilms and increases resistance to opsonic killing in the host
 
   
 0.991
algX
Putative alginate biosynthesis protein algx; Plays two roles in the biosynthesis of the exopolysaccharide alginate: protects alginate from degradation as the polymer traverses the periplasm, and also plays a role in its O-acetylation. Acetylation of alginate causes the cells in the biofilm to adhere better to lung epithelium, form microcolonies, and resist the effects of the host immune system and/or antibiotics. Displays a low acetylesterase activity in vitro using a pseudosubstrate, 3-carboxyumbelliferyl acetate. Probably has acetyltransferase activity in vivo

alg8
Glycosyltransferase like 2 family protein; Processive enzyme that polymerizes GDP-mannuronic acid
 
 
 0.968
algG
Poly(beta-d-mannuronate) c5 epimerase; Catalyzes the epimerization of beta-D-mannuronate to alpha-L- guluronate during the synthesis of the linear polysaccharide alginate . In addition, is part of a periplasmic protein complex that protects alginate from degradation by AlgL by channeling the newly formed alginate polymer through a scaffold that transfers the alginate polymer through the periplasmic space to the outer membrane secretin AlgE
 
  
 0.966
algK
Alginate biosynthesis protein algk; May be involved in the polymerization of mannuronate to alginate
 
 
 0.965
alg44
Alginate biosynthesis protein alg44; Required for alginate biosynthesis
 
  
 0.965
algE
Alginate production outer membrane protein; Has non-porin-like, channel-forming properties and probably functions as an alginate permeability pore
 
  
 0.963
algL
Poly(beta-d-mannuronate) lyase; Catalyzes the depolymerization of alginate by cleaving the beta-1,4 glycosidic bond between two adjacent sugar residues via a beta-elimination mechanism May serve to degrade mislocalized alginate that is trapped in the periplasmic space. Acts preferentially on non-acetylated alginate or its precursor mannuronan. Is able to catalyze cleavage adjacent to either mannuronate or guluronate residues in alginate. Exhaustive digestion of alginate by AlgL generates dimeric and trimeric products . In addition to its enzymatic function, AlgL appears to be required [...]
 
   
 0.960
algA
Mannose-1-phosphate guanylyltransferase / mannose-6-phosphate isomerase; Produces a precursor for alginate polymerization. The alginate layer provides a protective barrier against host immune defenses and antibiotics
