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

gltA
Glutamate synthase (large subunit); Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme; Belongs to the glutamate synthase family.
  
 
 0.942
gudB
Cryptic glutamate dehydrogenase; GudB seems to be intrinsically inactive, however spontaneous mutations removing a 9-bp direct repeat within the wild-type gudB sequence activated the GudB protein and allowed more-efficient utilization of amino acids of the glutamate family. This insertion presumably causes severe destabilization of the fold of the protein, leading to an inactive enzyme that is very quickly degraded. The cryptic GudB serves as a buffer that may compensate for mutations in the rocG gene and that can also be decryptified for the utilization of glutamate as a single carbon [...]

dat
D-alanine aminotransferase; Acts on the D-isomers of alanine, leucine, aspartate, glutamate, aminobutyrate, norvaline and asparagine. The enzyme transfers an amino group from a substrate D-amino acid to the pyridoxal phosphate cofactor to form pyridoxamine and an alpha-keto acid in the first half-reaction. The second half-reaction is the reverse of the first, transferring the amino group from the pyridoxamine to a second alpha-keto acid to form the product D-amino acid via a ping-pong mechanism. This is an important process in the formation of D-alanine and D-glutamate, which are essen [...]

rocG
Glutamate dehydrogenase; Devoted to catabolic function of glutamate (and other amino acids of the glutamate family) utilization as sole nitrogen source. It is not involved in anabolic function of glutamate biosynthesis since B.subtilis possesses only one route of glutamate biosynthesis from ammonia, catalyzed by glutamate synthase. RocG is unable to utilize glutamate or glutamine as sole carbon source and to synthesize glutamate, but it is involved in the utilization of arginine, and proline as carbon or nitrogen source. The catabolic RocG is essential for controlling gltAB expression [...]

ansA
Exported L-asparaginase; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme; Belongs to the asparaginase 1 family.

tyrA
Prephenate dehydrogenase; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme; Belongs to the prephenate/arogenate dehydrogenase family.
