Genes that are sometimes fused into single open reading frames.
STRING allows inspection of the interaction evidence for any given network. Choose any of the viewers above (disabled if not applicable in your network).
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.
colored nodes: query proteins and first shell of interactors
white nodes: second shell of interactors
empty nodes: proteins of unknown 3D structure
filled nodes: some 3D structure is known or predicted
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.
from curated databases
NH(3)-dependent NAD(+) synthetase; Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD. Uses ammonia as a nitrogen source (276 aa)
Predicted Functional Partners:
Probable nicotinate-nucleotide adenylyltransferase; Catalyzes the reversible adenylation of nicotinate mononucleotide (NaMN) to nicotinic acid adenine dinucleotide (NaAD) (170 aa)
NAD 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 (269 aa)
Nicotinate phosphoribosyltransferase; Catalyzes the synthesis of beta-nicotinate D- ribonucleotide from nicotinate and 5-phospho-D-ribose 1-phosphate at the expense of ATP (486 aa)
annotation not available (151 aa)
annotation not available (725 aa)
Bifunctional ligase/repressor BirA; Acts both as a biotin--[acetyl-CoA-carboxylase] ligase and a repressor (323 aa)
annotation not available (414 aa)
annotation not available (233 aa)
annotation not available (191 aa)
Nicotinate phosphoribosyltransferase; Catalyzes the synthesis of beta-nicotinate D- ribonucleotide from nicotinate and 5-phospho-D-ribose 1-phosphate at the expense of ATP (475 aa)
