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

mngBAlpha-mannosidase; May hydrolyze 6-phospho-mannosyl-D-glycerate to mannose-6- phosphate and glycerate; Belongs to the glycosyl hydrolase 38 family. (877 aa)    
Predicted Functional Partners:
mngA
Fused 2-O-a-mannosyl-D-glycerate specific PTS enzymes: IIA component/IIB component/IIC 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 mannosyl- D-glycerate transport. Also involved in thermoinduction of ompC.

melA
Alpha-galactosidase, NAD(P)-binding; Alpha-galactosidase; Protein involved in carbohydrate catabolic process and NAD biosynthetic process; Belongs to the glycosyl hydrolase 4 family.
     
 0.754
mngR
Transcriptional repressor for the mannosyl-D-glycerate catabolic operon; Represses mngA and mngB. Regulates its own expression.
 
  
 0.727
ycjN
Putative ABC sugar transporter periplasmic binding protein; Probably part of the binding-protein-dependent transport system YcjNOP; Belongs to the bacterial solute-binding protein 1 family.
 
     0.677
yphH
Putative NAGC-like transcriptional regulator; Protein involved in regulation of transcription, DNA-dependent; Belongs to the ROK (NagC/XylR) family.
  
  
 0.615
frvR
Putative frv operon regulator; Could be involved in the regulation of the transcription of the FRV operon.
 
    0.605
ycjR
Putative TIM alpha/beta barrel enzyme; Catalyzes the epimerization at C4 of 3-dehydro-D-gulosides leading to 3-dehydro-D-glucosides. Probably functions in a metabolic pathway that transforms D-gulosides to D-glucosides. Can use methyl alpha-3-dehydro-D-glucoside and methyl beta-3-dehydro-D-glucoside as substrates in vitro. However, the actual specific physiological substrates for this metabolic pathway are unknown. Cannot act on D- psicose, D-fructose, D-tagatose, D-sorbose, L-xylulose, or L-ribulose. Belongs to the hyi family.

ascF
Cellobiose/arbutin/salicin-specific PTS enzymes, IIB and IC components; 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 arbutin, cellobiose, and salicin transport.

ycjS
Putative NADH-binding oxidoreductase; Catalyzes the NADH-dependent reduction of the oxo group at C3 of 3-dehydro-D-glucosides leading to D-glucosides. Probably functions in a metabolic pathway that transforms D-gulosides to D-glucosides. Can use 3-dehydro-D-glucose, methyl alpha-3-dehydro-D-glucoside and methyl beta-3-dehydro-D-glucoside as substrates in vitro. However, the actual specific physiological substrates for this metabolic pathway are unknown. To a lesser extent, is also able to catalyze the reverse reactions, i.e. the NAD(+)-dependent oxidation of the hydroxyl group at C3 of [...]

yggW
HemN family putative oxidoreductase; Probably acts as a heme chaperone, transferring heme to the NarI subunit of the respiratory enzyme nitrate reductase; transfer may be stimulated by NADH. Binds one molecule of heme per monomer, possibly covalently. Heme binding is not affected by either [4Fe-4S] or S- adenosyl-L-methionine (SAM)-binding. Does not have coproporphyrinogen III dehydrogenase activity in vitro. Binds 1 [4Fe-4S] cluster. The cluster is coordinated with 3 cysteines and an exchangeable S-adenosyl-L-methionine (Probable).
