STRINGSTRING
ppnK protein (Vibrio vulnificus) - STRING interaction network
"ppnK" - NAD kinase in Vibrio vulnificus
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:
some 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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

Score
ppnKNAD kinase; Involved in the regulation of the intracellular balance of NAD and NADP, and is a key enzyme in the biosynthesis of NADP. Catalyzes specifically the phosphorylation on 2’-hydroxyl of the adenosine moiety of NAD to yield NADP (294 aa)    
Predicted Functional Partners:
nadE
NH(3)-dependent NAD(+) synthetase; Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD. Uses ammonia as a nitrogen source (276 aa)

pntB
NAD(P) transhydrogenase subunit beta; The transhydrogenation between NADH and NADP is coupled to respiration and ATP hydrolysis and functions as a proton pump across the membrane (464 aa)
     
 
  0.830
sthA
Soluble pyridine nucleotide transhydrogenase; Conversion of NADPH, generated by peripheral catabolic pathways, to NADH, which can enter the respiratory chain for energy generation; Belongs to the class-I pyridine nucleotide-disulfide oxidoreductase family (466 aa)
       
  0.826
grpE
Protein GrpE; Participates actively in the response to hyperosmotic and heat shock by preventing the aggregation of stress-denatured proteins, in association with DnaK and GrpE. It is the nucleotide exchange factor for DnaK and may function as a thermosensor. Unfolded proteins bind initially to DnaJ; upon interaction with the DnaJ-bound protein, DnaK hydrolyzes its bound ATP, resulting in the formation of a stable complex. GrpE releases ADP from DnaK; ATP binding to DnaK triggers the release of the substrate protein, thus completing the reaction cycle. Several rounds of ATP- dependent [...] (198 aa)

VV0861
Riboflavin biosynthesis protein RibD; 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 (368 aa)
