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

cobYConserved hypothetical protein; Guanylyltransferase that catalyzes the synthesis of adenosylcobinamide-GDP (AdoCbi-GDP) from adenosylcobinamide-phosphate (AdoCbi-P) and GTP. Is involved in adenosylcobalamin biosynthesis. Binds one GTP per dimer. Cannot use other NTPs or GDP. Does not display AdoCbi kinase activity. Is also able to catalyze the condensation of 2- phospho-L-lactate (LP) with GTP in vitro to form PPi and (2S)-lactyl-2- diphospho-5'-guanosine (LPPG), but is much less efficient than CofC, the presumed enzyme catalyzing this reaction in vivo. (196 aa)    
Predicted Functional Partners:
cobS
Cobalamin (5'-phosphate) synthase (cobS); Joins adenosylcobinamide-GDP and alpha-ribazole to generate adenosylcobalamin (Ado-cobalamin). Also synthesizes adenosylcobalamin 5'-phosphate from adenosylcobinamide-GDP and alpha-ribazole 5'- phosphate; Belongs to the CobS family.

MJ_1118
Conserved hypothetical protein; Similar to GB:AE000782 percent identity: 32.88; identified by sequence similarity; putative.
  
    0.964
cobD
Cobalamin biosynthesis protein B (cbiB); Converts cobyric acid to cobinamide by the addition of aminopropanol on the F carboxylic group.
 
  
  0.952
glmU
Glucose-1-phosphate thymidylyltransferase (strD); Catalyzes the last two sequential reactions in the de novo biosynthetic pathway for UDP-N-acetyl-glucosamine (UDP-GlcNAc). Responsible for the acetylation of GlcN-1-P to GlcNAc-1-P, and for the uridyl transfer from UTP to GlcNAc-1-P, to produce UDP-GlcNAc and pyrophosphate. Also catalyzes the reverse reaction, i.e. the cleavage of UDP-GlcNAc with pyrophosphate to form UTP and GlcNAc-1-P. To a lesser extent, is also able to use dUTP or dTTP as the nucleotide substrate, but not CTP, ATP or GTP; In the N-terminal section; belongs to the N- [...]
 
   
 0.896
dapF
Diaminopimelate epimerase (dapF); Catalyzes the stereoinversion of LL-2,6-diaminoheptanedioate (L,L-DAP) to meso-diaminoheptanedioate (meso-DAP), a precursor of L- lysine.
       0.827
MJ_1120
Conserved hypothetical protein; Similar to GB:AE000666 percent identity: 30.16; identified by sequence similarity; putative; Belongs to the LysR transcriptional regulatory family.
       0.827
MJ_1598
Conserved hypothetical protein; Similar to GP:1652098 percent identity: 35.67; identified by sequence similarity; putative; Belongs to the UPF0284 family.
 
     0.754
cbiA
Cobyrinic acid a,c-diamide synthase (cbiA); 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. Involved in the biosynthesis of the unique nickel-containing tetrapyrrole coenzyme F430, the prosthetic group of methyl-coenzyme M reductase (MCR), which plays a key role in methanogenesis and anaerobic methane oxidation. Catalyzes the ATP- dependent amidation of the two carboxylate groups at positions a and c of Ni-sirohydrochlorin, using L-glutamine or ammonia as the nitrogen source.
     
 0.714
cbiF
Cobalamin biosynthesis precorrin-3 methylase (cbiF); Catalyzes the methylation of C-11 in cobalt-precorrin-4 to form cobalt-precorrin-5A.
      
 0.706
metE
5-methyltetrahydropteroyltriglutamate- homocysteine methyltransferase (metE); Catalyzes the transfer of a methyl group to L-homocysteine resulting in methionine formation. Can use methylcobalamin and methylcobinamide as methyl donors, but methylcobalamin is not considered to be the physiological substrate (By similarity).
