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

ipiIntracellular proteinase inhibitor BsuPI; Directly regulates the major intracellular proteinase (ISP-1) activity in vivo. Inhibits ISP-1 in the early stages of sporulation. It may be then inactivated by a membrane-bound proteinase. (119 aa)    
Predicted Functional Partners:
yitT
Putative integral inner membrane protein; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pm: putative membrane component.
  
    0.834
aprE
Serine alkaline protease (subtilisin E); Subtilisin is an extracellular alkaline serine protease, it catalyzes the hydrolysis of proteins and peptide amides; Belongs to the peptidase S8 family.
     
 0.633
yitS
Conserved hypothetical protein; May bind long-chain fatty acids, such as palmitate, and may play a role in lipid transport or fatty acid metabolism.
