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:
some 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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

yfeWUPF0214 protein YfeW; Putative beta-lactamase; Protein involved in carbohydrate catabolic process; Belongs to the UPF0214 family (434 aa)    
Predicted Functional Partners:
murP
PTS system N-acetylmuramic acid-specific EIIBC component; The phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS), a major carbohydrate active transport system, catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. This system is involved in N-acetylmuramic acid (MurNAc) transport, yielding cytoplasmic MurNAc-6-P. Is responsible for growth on MurNAc as the sole source of carbon and energy. Is also able to take up anhydro-N-acetylmuramic acid (anhMurNAc), but cannot phosphorylate the carbon 6, pr [...]

murR
HTH-type transcriptional regulator MurR; Represses the expression of the murPQ operon involved in the uptake and degradation of N-acetylmuramic acid (MurNAc). Binds to two adjacent inverted repeats within the operator region. MurNAc 6-phosphate, the substrate of MurQ, is the specific inducer that weakens binding of MurR to the operator. Also represses its own transcription
 
   
 0.971
mrcA
Penicillin-binding protein 1A; 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
     
 0.968
dacA
D-alanyl-D-alanine carboxypeptidase DacA; Removes C-terminal D-alanyl residues from sugar-peptide cell wall precursors
     
 0.950
dacD
D-alanyl-D-alanine carboxypeptidase DacD; Removes C-terminal D-alanyl residues from sugar-peptide cell wall precursors; Belongs to the peptidase S11 family
     
 0.925
ldcA
Murein tetrapeptide carboxypeptidase; Releases the terminal D-alanine residue from the cytoplasmic tetrapeptide recycling product L-Ala-gamma-D-Glu-meso- Dap-D-Ala. To a lesser extent, can also cleave D-Ala from murein derivatives containing the tetrapeptide, i.e. MurNAc-tetrapeptide, UDP-MurNAc-tetrapeptide, GlcNAc-MurNAc-tetrapeptide, and GlcNAc- anhMurNAc-tetrapeptide. Does not act on murein sacculi or cross- linked muropeptides. The tripeptides produced by the LcdA reaction can then be reused as peptidoglycan building blocks; LcdA is thereby involved in murein recycling. Is also es [...]
 
   
 0.919
nagZ
Beta-hexosaminidase; 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. Cleaves GlcNAc linked beta-1,4 to MurNAc tripeptides
   
 0.913
ldtC
Probable L,D-transpeptidase YcfS; Responsible, at least in part, for anchoring of the major outer membrane lipoprotein (Lpp, also known as the Braun lipoprotein) to the peptidoglycan via a meso-diaminopimelyl-L- Lys- bond on the terminal residue of Lpp
    
 0.908
murQ
N-acetylmuramic acid 6-phosphate etherase; Specifically catalyzes the cleavage of the D-lactyl ether substituent of MurNAc 6-phosphate, producing GlcNAc 6- phosphate and D-lactate. Is required for growth on MurNAc as the sole source of carbon and energy. Together with AnmK, is also required for the utilization of anhydro-N-acetylmuramic acid (anhMurNAc) either imported from the medium or derived from its own cell wall murein, and thus plays a role in cell wall recycling

Penicillin-binding protein 1B; 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
