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

MJ_0058Ammonium transporter (amtB); Similar to SP:P37905 PID:1103924 GB:U00096 PID:1773135 PID:1786656 percent identity: 34.19; identified by sequence similarity; putative. (391 aa)    
Predicted Functional Partners:
MJ_0059
Nitrogen regulatory protein P-II (glnB); Similar to GP:1279429 percent identity: 61.61; identified by sequence similarity; putative.
 
 
 0.996
MJ_1344
Nitrogen regulatory protein P-II (glnB); Similar to GP:1279429 percent identity: 59.82; identified by sequence similarity; putative; Belongs to the P(II) protein family.
 
 
 0.994
nifH
Nitrogenase iron protein (nifH); The key enzymatic reactions in nitrogen fixation are catalyzed by the nitrogenase complex, which has 2 components: the iron protein and the molybdenum-iron protein.
  
  
 0.589
MJ_0057
Na+/H+ antiporter; This is a Na(+)/H(+) antiporter. Can also transport lithium. Belongs to the monovalent cation:proton antiporter 1 (CPA1) transporter (TC 2.A.36) family.
  
  
 0.582
glnA
Glutamine synthetase (glnA); Probably involved in nitrogen metabolism via ammonium assimilation. Catalyzes the ATP-dependent biosynthesis of glutamine from glutamate and ammonia. Beta-glutamate is a much poorer substrate than alpha-glutamate.
  
  
 0.514
ribB
GTP cyclohydrolase II (ribA); Catalyzes the conversion of D-ribulose 5-phosphate to formate and 3,4-dihydroxy-2-butanone 4-phosphate.
       0.497
ribK
Conserved hypothetical protein; Catalyzes the CTP-dependent phosphorylation of riboflavin (vitamin B2) to form flavin mononucleotide (FMN). Can also utilize UTP as the phosphate donor, although less efficiently, and it is unclear if ATP and GTP can also serve as substrates or not.
       0.492
wtpA
Conserved hypothetical protein; Part of the ABC transporter complex WtpABC involved in molybdate/tungstate import. Binds tungstate and molybdate (By similarity).
  
  
 0.437
MJ_1351
Glutamate synthase (gltB); Similar to GB:M18747 SP:P09831 GB:L20253 GB:M33743 GB:M68876 percent identity: 40.46; identified by sequence similarity; putative; Belongs to the glutamate synthase family.
