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

otsAAlpha,alpha-trehalose-phosphate synthase (UDP-forming); Involved in the production of glycogen and alpha-glucan via the TreS-Pep2 branch involved in the biosynthesis of maltose-1- phosphate (M1P), and probably in the osmoprotection via the biosynthesis of trehalose. Catalyzes the transfer of glucose from UDP-glucose (UDP-Glc) to glucose-6-phosphate (Glc-6-P) to form trehalose-6-phosphate. ADP-Glc, CDP-Glc, GDP- Glc and TDP-Glc are also glucosyl donors, however, when the pyrimidine sugar nucleotides (CDP-Glc, TDP-Glc and UDP-Glc) are used as substrates, there is an absolute requirement [...] (503 aa)    
Predicted Functional Partners:
otsB
Trehalose-phosphatase; Removes the phosphate from trehalose 6-phosphate to produce free trehalose.
 
 0.999
glgC
Glucose-1-phosphate adenylyltransferase; Involved in the biosynthesis of ADP-glucose building block, required in the biosynthesis of maltose-1-phosphate (M1P) and in the elongation reactions to produce linear alpha-1,4-glucans. Catalyzes the reaction between ATP and alpha-D-glucose 1-phosphate (G1P) to produce pyrophosphate and ADP-Glc.
  
 
 0.986
galU
UTP-glucose-1-phosphate uridylyltransferase; Identified by match to protein family HMM PF00483.
  
 
 0.979
treS
Trehalose synthase; Catalyzes the reversible interconversion of maltose and trehalose by transglucosylation. Maltose is the preferred substrate. To a lesser extent, also displays amylase activity, catalyzing the endohydrolysis of (1->4)-alpha-D- glucosidic linkages in glycogen and maltooligosaccharides such as maltoheptaose, to produce maltose which then can be converted to trehalose. TreS plays a key role in the utilization of trehalose for the production of glycogen and alpha-glucan via the TreS-Pep2 branch involved in the biosynthesis of maltose-1-phosphate (M1P). Might also functio [...]
 
  
 0.972
treZ
Malto-oligosyltrehalose trehalohydrolase; Identified by match to protein family HMM PF00128; match to protein family HMM PF02922; match to protein family HMM TIGR02402.
  
  
 0.958
glgE
Alpha-amylase family protein; Maltosyltransferase that uses maltose 1-phosphate (M1P) as the sugar donor to elongate linear or branched alpha-(1->4)-glucans. Is also able to catalyze the reverse reaction in vitro. Cannot use glucose 1-phosphate as substrate. Is involved in a branched alpha-glucan biosynthetic pathway from trehalose, together with TreS, Mak and GlgB.
 
  
 0.955
mak
Trehalose synthase-fused probable maltokinase; Catalyzes the ATP-dependent phosphorylation of maltose to maltose 1-phosphate (Probable). Is involved in a branched alpha-glucan biosynthetic pathway from trehalose, together with TreS, GlgE and GlgB.
  
  
 0.954
glgB
1,4-alpha-glucan branching enzyme; Catalyzes the formation of the alpha-1,6-glucosidic linkages in glycogen by scission of a 1,4-alpha-linked oligosaccharide from growing alpha-1,4-glucan chains and the subsequent attachment of the oligosaccharide to the alpha-1,6 position.
  
  
 0.910
ABK71277.1
Beta-glucoside-specific EII permease; Identified by match to protein family HMM PF00358; match to protein family HMM TIGR00830.
   
 
  0.901
ABK72415.1
Glycoside hydrolase; Catalyzes the hydrolysis of alpha,alpha-trehalose into two molecules of D-glucose. Does not hydrolyze maltose, isomaltose, sucrose, cellobiose, p-nitrophenyl-alpha-D-glucopyranoside, and methyl- alpha-D-glucopyranoside. Is also inactive on alpha,beta-trehalose, beta,beta-trehalose, alpha,alpha-trehalose-6,6'-dibehenate, trehalulose, nigerose, and trehalose dimycolate.
