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

higA3Possible transcriptional regulatory protein; Putative antitoxin component of a type II toxin-antitoxin (TA) system. Its cognate toxin would be HigB3. (109 aa)    
Predicted Functional Partners:
higB3
Conserved hypothetical protein; Putative toxic component of a type II toxin-antitoxin (TA) system. Its cognate antitoxin would be HigA3. Not toxic upon expression in M.smegmatis.

lysG
Probable transcriptional regulatory protein (probably LysR-family); Positively regulates the expression of the exporter LysE and represses its own expression. Activity requires the presence of a coinducer, lysine or histidine. Acts by binding to lysG-lysE promoter region. Also up-regulates the expression of ppsB, ppsC and ppsD, by binding to the upstream region of ppsB.
