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

algKMay be involved in the polymerization of mannuronate to alginate (475 aa)    
Predicted Functional Partners:
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.
 
   
 0.999
algE
Has non-porin-like, channel-forming properties and probably functions as an alginate permeability pore

alg44
Required for alginate biosynthesis.
 
  
 0.997
algG
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 (PubMed:12581364, PubMed:15968068).

algL
Catalyzes the depolymerization of alginate by cleaving the beta-1,4 glycosidic bond between two adjacent sugar residues via a beta-elimination mechanism (PubMed:8370530, PubMed:8335634, PubMed:23215237). 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 appe [...]

alg8
Processive enzyme that polymerizes GDP-mannuronic acid.
 
 
 0.992
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
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.

 0.965
algD
Catalyzes the oxidation of guanosine diphospho-D-mannose (GDP-D-mannose) to GDP-D-mannuronic acid, a precursor for alginate polymerization. The alginate layer causes a mucoid phenotype and provides a protective barrier against host immune defenses and antibiotics
