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

MCA2288Putative cobalamin biosynthetic protein CobC; Identified by similarity to SP:P21633. (328 aa)    
Predicted Functional Partners:
cobQ
Cobyric acid synthase CobQ; Catalyzes amidations at positions B, D, E, and G on adenosylcobyrinic A,C-diamide. NH(2) groups are provided by glutamine, and one molecule of ATP is hydrogenolyzed for each amidation. Belongs to the CobB/CobQ family. CobQ subfamily.
 
 0.997
cobD
Cobalamin biosynthesis protein CobD; Converts cobyric acid to cobinamide by the addition of aminopropanol on the F carboxylic group.
 
  
 0.996
cobU
Bifunctional cobalamin biosynthesis protein CobU; Catalyzes ATP-dependent phosphorylation of adenosylcobinamide and addition of GMP to adenosylcobinamide phosphate.
 
 
 0.977
cobA
cob(I)alamin adenosyltransferase; Required for both de novo synthesis of the corrin ring for the assimilation of exogenous corrinoids. Participates in the adenosylation of a variety of incomplete and complete corrinoids.
 
  
 0.955
MCA1814
Putative ATP:cob(I)alamin adenosyltransferase; Identified by similarity to GP:17429685; match to protein family HMM PF01923; match to protein family HMM TIGR00636; Belongs to the Cob(I)alamin adenosyltransferase family.
    
 0.912
hisB
Imidazoleglycerol-phosphate dehydratase; Identified by match to protein family HMM PF00475.
 
  
 0.772
hisI
phosphoribosyl-AMP cyclohydrolase; Catalyzes the hydrolysis of the adenine ring of phosphoribosyl-AMP.
 
  
 0.770
hisD
Histidinol dehydrogenase; Catalyzes the sequential NAD-dependent oxidations of L- histidinol to L-histidinaldehyde and then to L-histidine.
 
  
 0.763
cobB
Cobyrinic acid a,c-diamide synthase; Catalyzes the ATP-dependent amidation of the two carboxylate groups at positions a and c of cobyrinate, using either L-glutamine or ammonia as the nitrogen source; Belongs to the CobB/CbiA family.
 
  
 0.757
hisG
ATP phosphoribosyltransferase; Catalyzes the condensation of ATP and 5-phosphoribose 1- diphosphate to form N'-(5'-phosphoribosyl)-ATP (PR-ATP). Has a crucial role in the pathway because the rate of histidine biosynthesis seems to be controlled primarily by regulation of HisG enzymatic activity. Belongs to the ATP phosphoribosyltransferase family. Short subfamily.
