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

amgKConserved protein of unknown function; Sugar kinase that catalyzes the ATP-dependent phosphorylation of N-acetylmuramate (MurNAc) and N-acetylglucosamine (GlcNAc) at its C1 hydroxyl group, leading to MurNAc alpha-1P and GlcNAc alpha-1P, respectively. Is involved in peptidoglycan recycling as part of a cell wall recycling pathway that bypasses de novo biosynthesis of the peptidoglycan precursor UDP-MurNAc. Plays a role in intrinsic resistance to fosfomycin, which targets the de novo synthesis of UDP- MurNAc. Is also able to use N-acetylgalactosamine (GalNAc) as a substrate, but not N-ac [...] (339 aa)    
Predicted Functional Partners:
murU
Nucleotidyltransferase family protein; Catalyzes the formation of UDP-N-acetylmuramate (UDP-MurNAc), a crucial precursor of the bacterial peptidoglycan cell wall, from UTP and MurNAc-alpha-1P. Is involved in peptidoglycan recycling as part of a cell wall recycling pathway that bypasses de novo biosynthesis of the peptidoglycan precursor UDP-MurNAc. Plays a role in intrinsic resistance to fosfomycin, which targets the de novo synthesis of UDP-MurNAc. Is not able to use GlcNAc-alpha-1P and GalNAc-alpha-1P as substrates. Cannot accept other nucleotide triphosphates (ATP, CTP, TTP, or GTP) [...]

nagZ
beta-N-acetylglucosaminidase; Plays a role in peptidoglycan recycling by cleaving the terminal beta-1,4-linked N-acetylglucosamine (GlcNAc) from peptide- linked peptidoglycan fragments, giving rise to free GlcNAc, anhydro-N- acetylmuramic acid and anhydro-N-acetylmuramic acid-linked peptides. Belongs to the glycosyl hydrolase 3 family. NagZ subfamily.
 
  
 0.986
gph
Phosphoglycolate phosphatase 2; Specifically catalyzes the dephosphorylation of N- acetylmuramate 6-phosphate (MurNAc-6P) to MurNac. Is involved in peptidoglycan recycling as part of a cell wall recycling pathway that bypasses de novo biosynthesis of the peptidoglycan precursor UDP- MurNAc. Plays a role in intrinsic resistance to fosfomycin, which targets the de novo synthesis of UDP-MurNAc. Shows a very low activity on GlcNAc-6P, and neither alpha-1-phosphorylated MurNAc, GlcNAc, or glucose nor glucosamine-6P or glucose-6P can be used as a substrate. Belongs to the HAD-like hydrolase [...]

glmU
N-acetyl glucosamine-1-phosphate uridyltransferase/glucosamine-1-phosphate acetyl transferase; Catalyzes the last two sequential reactions in the de novo biosynthetic pathway for UDP-N-acetylglucosamine (UDP-GlcNAc). The C- terminal domain catalyzes the transfer of acetyl group from acetyl coenzyme A to glucosamine-1-phosphate (GlcN-1-P) to produce N- acetylglucosamine-1-phosphate (GlcNAc-1-P), which is converted into UDP-GlcNAc by the transfer of uridine 5-monophosphate (from uridine 5- triphosphate), a reaction catalyzed by the N-terminal domain. In the C-terminal section; belongs to [...]

mpl
UDP-N-acetylmuramate:L-alanyl-gamma-D-glutamyl- meso-diaminopimelate ligase; Reutilizes the intact tripeptide L-alanyl-gamma-D-glutamyl- meso-diaminopimelate by linking it to UDP-N-acetylmuramate. Belongs to the MurCDEF family. Mpl subfamily.
  
  
 0.883
ampG
Muropeptide permease AmpG.
 
   
 0.881
anmK
Anhydro-N-acetylmuramic acid kinase; Catalyzes the specific phosphorylation of 1,6-anhydro-N- acetylmuramic acid (anhMurNAc) with the simultaneous cleavage of the 1,6-anhydro ring, generating MurNAc-6-P (By similarity). Is required for the utilization of anhMurNAc either imported from the medium or derived from its own cell wall murein, and thus plays a role in cell wall recycling. Contributes to intrinsic fosfomycin resistance in P.putida.

murA
UDP-N-acetylglucosamine 1-carboxyvinyltransferase; Cell wall formation. Adds enolpyruvyl to UDP-N- acetylglucosamine; Belongs to the EPSP synthase family. MurA subfamily.

argB
Acetylglutamate kinase; Catalyzes the ATP-dependent phosphorylation of N-acetyl-L- glutamate; Belongs to the acetylglutamate kinase family. ArgB subfamily.
