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

lrgBAntiholin factor; Inhibits the expression or activity of extracellular murein hydrolases by interacting, possibly with LrgA, with the holin-like protein CidA. The LrgAB and CidA proteins may affect the proton motive force of the membrane. May be involved in programmed cell death (PCD), possibly triggering PCD in response to antibiotics and environmental stresses; Belongs to the CidB/LrgB family. LrgB subfamily. (231 aa)    
Predicted Functional Partners:
lrgA
Antiholin factor; Inhibits the expression or activity of extracellular murein hydrolases by interacting, possibly with LrgB, with the holin-like protein CidA. The LrgAB and CidA proteins may affect the proton motive force of the membrane. May be involved in programmed cell death (PCD), possibly triggering PCD in response to antibiotics and environmental stresses; Belongs to the CidA/LrgA family. LrgA subfamily.

lytS
Two-component sensor histidine kinase [LytT]; Member of the two-component regulatory system LytS/LytT that probably regulates genes involved in cell wall metabolism.
 
   
 0.965
cidA
Holin regulator of murein hydrolases; Increases the activity of extracellular murein hydrolases possibly by mediating their export via hole formation. Inhibited by the antiholin-like proteins LrgAB. In an unstressed cell, the LrgAB products probably inhibit the function of the CidA protein. When a cell is stressed by the addition of antibiotics or by other factors in the environment, CidA possibly oligomerizes within the bacterial cell membrane, creating lesions that disrupt the proton motive force, which in turn results in loss of cell viability. These lesions are also hypothesized to [...]
