STRING protein interaction 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.
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 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
protein homology

dadXIsomerizes L-alanine to D-alanine which is then oxidized to pyruvate by DadA (356 aa)    
Predicted Functional Partners:
Catalyzes the oxidative deamination of D-amino acids. Has broad substrate specificity; is mostly active on D-alanine, and to a lesser extent, on several other D-amino acids such as D-methionine, D- serine and D-proline, but not on L-alanine. Participates in the utilization of L-alanine and D-alanine as the sole source of carbon, nitrogen and energy for growth. Is also able to oxidize D-amino acid analogs such as 3,4-dehydro-D-proline, D-2-aminobutyrate, D-norvaline, D-norleucine, cis-4-hydroxy-D-proline, and DL-ethionine.

Involved in the biosynthesis of alanine.
Master enzyme that delivers sulfur to a number of partners involved in Fe-S cluster assembly, tRNA modification or cofactor biosynthesis. Catalyzes the removal of elemental sulfur from cysteine to produce alanine. Functions as a sulfur delivery protein for Fe-S cluster synthesis onto IscU, an Fe-S scaffold assembly protein, as well as other S acceptor proteins. Preferentially binds to disordered IscU on which the Fe-S is assembled, IscU converts to the structured state and then dissociates from IscS to transfer the Fe-S to an acceptor protein. Also functions as a selenium delivery prot [...]
Involved in cell wall formation. Catalyzes the final step in the synthesis of UDP-N-acetylmuramoyl-pentapeptide, the precursor of murein
Catalyzes the interconversion of L-alanine and D-alanine. Provides the D-alanine required for cell wall biosynthesis.
Acts both as a biotin--[acetyl-CoA-carboxylase] ligase and a biotin-operon repressor. In the presence of ATP, BirA activates biotin to form the BirA-biotinyl-5'-adenylate (BirA-bio-5'-AMP or holoBirA) complex. HoloBirA can either transfer the biotinyl moiety to the biotin carboxyl carrier protein (BCCP) subunit of acetyl-CoA carboxylase, or bind to the biotin operator site and inhibit transcription of the operon.
