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.

Predicted Functional Partners:
nadB
L-aspartate oxidase; Catalyzes the oxidation of L-aspartate to iminoaspartate.
 
 0.999
nadC
Similar to Escherichia coli nicotinate-nucleotide pyrophosphorylase [carboxylating] NadC or b0109 SWALL:NADC_ECOLI (SWALL:P30011) (296 aa) fasta scores: E(): 8.2e-73, 68.94% id in 293 aa; Belongs to the NadC/ModD family.
 
 
 0.999
pnuC
Nicotinamide mononucleotide transport protein; Similar to Escherichia coli, and Shigella flexneri protein PnuC or b0751 or sf0553 SWALL:PNUC_ECOLI (SWALL:P31215) (239 aa) fasta scores: E(): 2.9e-72, 73.64% id in 239 aa, and to Salmonella typhimurium protein PnuC or stm0757 SWALL:PNUC_SALTY (SWALL:P24520) (239 aa) fasta scores: E(): 3e-74, 76.05% id in 238 aa.

ribD
Riboflavin biosynthesis protein; Converts 2,5-diamino-6-(ribosylamino)-4(3h)-pyrimidinone 5'- phosphate into 5-amino-6-(ribosylamino)-2,4(1h,3h)-pyrimidinedione 5'- phosphate; In the C-terminal section; belongs to the HTP reductase family.
  
  
 0.725
tatB
Sec-independent protein translocase; Part of the twin-arginine translocation (Tat) system that transports large folded proteins containing a characteristic twin- arginine motif in their signal peptide across membranes. Together with TatC, TatB is part of a receptor directly interacting with Tat signal peptides. TatB may form an oligomeric binding site that transiently accommodates folded Tat precursor proteins before their translocation.

gmk
Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
