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

amiCN-acetylmuramoyl-L-alanine amidase; Cell-wall hydrolase involved in septum cleavage during cell division. Can also act as powerful autolysin in the presence of murein synthesis inhibitors; Belongs to the N-acetylmuramoyl-L-alanine amidase 3 family. (417 aa)    
Predicted Functional Partners:
ftsN
Essential cell division protein; Essential cell division protein that activates septal peptidoglycan synthesis and constriction of the cell. Acts on both sides of the membrane, via interaction with FtsA in the cytoplasm and interaction with the FtsQBL complex in the periplasm. These interactions may induce a conformational switch in both FtsA and FtsQBL, leading to septal peptidoglycan synthesis by FtsI and associated synthases (Probable). Required for full FtsI activity. Required for recruitment of AmiC to the septal ring. Belongs to the FtsN family.
   
 
 0.969
nlpD
Activator of AmiC murein hydrolase activity, lipoprotein; Activator of the cell wall hydrolase AmiC. Required for septal murein cleavage and daughter cell separation during cell division.
 
   
 0.966
amiB
N-acetylmuramoyl-l-alanine amidase II; Cell-wall hydrolase involved in septum cleavage during cell division. Can also act as powerful autolysin in the presence of murein synthesis inhibitors.
  
  
0.944
amiA
N-acetylmuramoyl-l-alanine amidase I; Cell-wall hydrolase involved in septum cleavage during cell division. Can also act as powerful autolysin in the presence of murein synthesis inhibitors.
  
 
0.915
ftsI
Transpeptidase involved in septal peptidoglycan synthesis; Essential cell division protein that catalyzes cross-linking of the peptidoglycan cell wall at the division septum. Required for localization of FtsN. Belongs to the transpeptidase family. FtsI subfamily.
 
  
 0.911
ftsA
ATP-binding cell division FtsK recruitment protein; Essential cell division protein that assists in the assembly of the Z ring. May serve as the principal membrane anchor for the Z ring. Also required for the recruitment to the septal ring of the downstream cell division proteins FtsK, FtsQ, FtsL, FtsI and FtsN. Binds ATP.
 
   
 0.901
mrcB
Fused glycosyl transferase and transpeptidase; Cell wall formation. Synthesis of cross-linked peptidoglycan from the lipid intermediates. The enzyme has a penicillin-insensitive transglycosylase N-terminal domain (formation of linear glycan strands) and a penicillin-sensitive transpeptidase C-terminal domain (cross- linking of the peptide subunits); In the N-terminal section; belongs to the glycosyltransferase 51 family.
    
 
 0.894
ftsQ
Divisome assembly protein, membrane anchored protein involved in growth of wall at septum; Essential cell division protein. May link together the upstream cell division proteins, which are predominantly cytoplasmic, with the downstream cell division proteins, which are predominantly periplasmic. May control correct divisome assembly. Belongs to the FtsQ/DivIB family. FtsQ subfamily.
  
  
 0.891
ftsE
Cell division ATP-binding protein; Part of the ABC transporter FtsEX involved in cellular division. Important for assembly or stability of the septal ring.
     
 0.889
ftsW
Putative lipid II flippase; Peptidoglycan polymerase that is essential for cell division (Probable). Functions probably in conjunction with the penicillin- binding protein 3 (ftsI). Required for localization of FtsI.
