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

nasFuroporphyrin-III C-methyltransferase; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme; Belongs to the precorrin methyltransferase family. (483 aa)    
Predicted Functional Partners:
hemC
Porphobilinogen deaminase (hydroxymethylbilane synthase); Tetrapolymerization of the monopyrrole PBG into the hydroxymethylbilane pre-uroporphyrinogen in several discrete steps. Belongs to the HMBS family.
 0.999
sirC
Precorrin-2 dehydrogenase; Catalyzes the dehydrogenation of precorrin-2 to form sirohydrochlorin which is used as a precursor in both siroheme biosynthesis and in the anaerobic branch of adenosylcobalamin biosynthesis; Belongs to the precorrin-2 dehydrogenase / sirohydrochlorin ferrochelatase family.
 
 0.993
hemD
Uroporphyrinogen III cosynthase; Catalyzes cyclization of the linear tetrapyrrole, hydroxymethylbilane, to the macrocyclic uroporphyrinogen III. Belongs to the uroporphyrinogen-III synthase family.
 
 
 0.986
hemB
Delta-aminolevulinic acid dehydratase (porphobilinogen synthase); Catalyzes an early step in the biosynthesis of tetrapyrroles. Binds two molecules of 5-aminolevulinate per subunit, each at a distinct site, and catalyzes their condensation to form porphobilinogen (By similarity).
 
 
 0.981
nasD
Assimilatory nitrite reductase subunit; Required for nitrite assimilation.
 
  
 0.975
yjjA
Putative enzyme; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme.
 
 
 0.954
nasE
Assimilatory nitrite reductase subunit; Required for nitrite assimilation. Required for activity of the reductase (By similarity).
 
  
 0.951
hemE
Uroporphyrinogen III decarboxylase; Catalyzes the decarboxylation of four acetate groups of uroporphyrinogen-III to yield coproporphyrinogen-III.
  
 
 0.943
sumT
Uroporphyrinogen III and precorrin-1 C-methyltransferase; Catalyzes both methylations at C-2 and C-7 of uroporphyrinogen III leading to precorrin-1 and precorrin-2; their oxidative esterification gives respectively factor I octamethyl ester and sirohydrochlorin.
 
 
0.920
hemA
glutamyl-tRNA reductase; Catalyzes the NADPH-dependent reduction of glutamyl-tRNA(Glu) to glutamate 1-semialdehyde (GSA).
 
  
 0.903
