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

ABB49571.1Helix-turn-helix domain of resolvase-like protein; Alternative locus ID: P9312_05351. (116 aa)    
Predicted Functional Partners:
proS
prolyl-tRNA synthetase; Catalyzes the attachment of proline to tRNA(Pro) in a two- step reaction: proline is first activated by ATP to form Pro-AMP and then transferred to the acceptor end of tRNA(Pro). As ProRS can inadvertently accommodate and process non-cognate amino acids such as alanine and cysteine, to avoid such errors it has two additional distinct editing activities against alanine. One activity is designated as 'pretransfer' editing and involves the tRNA(Pro)-independent hydrolysis of activated Ala-AMP. The other activity is designated 'posttransfer' editing and involves dea [...]

psb27
Photosystem II reaction center Psb27 protein-like protein; Plays a role in the repair and/or biogenesis of the calcium- manganese-oxide cluster on the lumenal face of the thylakoid membrane. Its presence in a photosystem II (PSII) preparation prevents binding of some small extrinsic subunits and thus assembly of calcium-manganese- oxide cluster.
       0.608
ppa
Inorganic diphosphatase; Catalyzes the hydrolysis of inorganic pyrophosphate (PPi) forming two phosphate ions.

ABB49572.1
Reverse transcriptase (RNA-dependent)-like protein; Alternative locus ID: P9312_05361.
       0.529
ABB49574.1
Conserved hypothetical protein; Alternative locus ID: P9312_05381; Belongs to the ArsC family.
       0.529
purA
Adenylosuccinate synthetase; Plays an important role in the de novo pathway of purine nucleotide biosynthesis. Catalyzes the first committed step in the biosynthesis of AMP from IMP; Belongs to the adenylosuccinate synthetase family.
       0.511
ABB49567.1
Carbohydrate kinase-like protein; Alternative locus ID: P9312_05311; Belongs to the carbohydrate kinase PfkB family.
       0.496
ABB49575.1
Signal peptidase I, Serine peptidase, MEROPS family S26A; Alternative locus ID: P9312_05391; Belongs to the peptidase S26 family.
