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

ribKConserved 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. (136 aa)    
Predicted Functional Partners:
ribL
Glycerol-3-phosphate cytidyltransferase (taqD); Catalyzes the transfer of the AMP portion of ATP to flavin mononucleotide (FMN) to produce flavin adenine dinucleotide (FAD) coenzyme. To a lesser extent, is also able to utilize other nucleotides such as CTP and GTP as substrates, producing the modified coenzymes, flavin cytosine dinucleotide (FCD) and flavin guanine dinucleotide (FGD), respectively. Does not catalyze the reverse reaction to produce FMN and ATP from FAD and PPi. Does not function as a glycerol-3- phosphate cytidylyltransferase, as previously annotated in the complete gen [...]
