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

otsB2Trehalose 6-phosphate phosphatase OtsB2 (trehalose-phosphatase) (TPP); Removes the phosphate from trehalose 6-phosphate to produce free trehalose. (391 aa)    
Predicted Functional Partners:
otsA
Trehalose-6-phosphate synthase; 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 D-glucose 6- phosphate (Glc-6-P) to form trehalose-6-phosphate. Is specific for the glucosyl acceptor (Glc-6-P cannot be replaced by either mannose-6-P, fructose-6-P or glucosamine-6-P), but any of the glucose sugar nucleotides can be used as glucosyl donors. It is more active with th [...]

treZ
Maltooligosyltrehalose trehalohydrolase TreZ; Is involved in the biosynthesis of trehalose but not in that of capsular glucan and glycogen.
 
 0.994
treS
Trehalose synthase TreS; Catalyzes the reversible interconversion of maltose and trehalose by transglucosylation. 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 function as a sensor and/or regulator of trehalose levels [...]

Rv2402
Conserved protein; Catalyzes the hydrolysis of alpha,alpha-trehalose into two molecules of D-glucose.
 
 
 0.988
otsB1
Rv2006, (MTCY39.11c), len: 1327 aa. OtsB1,trehalose-6-phosphate phosphatase (see citations below). Belongs to Glycosyl hydrolases family 65. Note that previously known as otsB. Predicted possible vaccine candidate (See Zvi et al., 2008).
 
0.987
Rv3401
Conserved protein; Rv3401, (MTCY78.27c), len: 786 aa. Conserved protein, may be an hydrolase or a transferase, equivalent to Q49736|ML0392|B1620_F1_30 hypothetical 88.1 KDA protein from Mycobacterium leprae (792 aa), FASTA scores: opt: 4820, E(): 0, (91.45% identity in 782 aa overlap). Also highly similar to Q9L2I8|SCF42.31c putative glycosyl transferase from Streptomyces coelicolor (792 aa), FASTA scores: opt: 3060, E(): 2.9e-179, (59.25% identity in 785 aa overlap); and similar to others e.g. Q9K109|NMB0390 maltose phosphorylase from Neisseria meningitidis (serogroup B) (752 aa), FAS [...]

treY
Maltooligosyltrehalose synthase TreY; Catalyzes the conversion of maltooligosaccharide into the non-reducing saccharide, maltooligosyl trehalose (alpha-maltooligosyl alpha-D-glucoside) by intramolecular transglycosylation.
 
  
 0.959
glgE
Probable glucanase GlgE; Essential maltosyltransferase that uses maltose 1-phosphate (M1P) as the sugar donor to elongate linear or branched alpha-(1->4)- glucans. Maltooligosaccharides with a degree of polymerization (DP) superior or equal to 4 are efficient acceptors, with DP5 being optimal in the GlgE-catalyzed polymerization with M1P. Is specific for the alpha-anomer of M1P as substrate, since the beta-anomer of M1P gives no activity. Exhibits an alpha-retaining catalytic mechanism. Is also able to catalyze the reverse reaction in vitro, releasing M1P from glycogen in the presence [...]

mak
Maltokinase Mak; Catalyzes the ATP-dependent phosphorylation of maltose to maltose 1-phosphate (By similarity). Is involved in a branched alpha- glucan biosynthetic pathway from trehalose, together with TreS, GlgE and GlgB; Belongs to the aminoglycoside phosphotransferase family.
 
  
 0.834
glgB
1,4-alpha-glucan branching enzyme GlgB (glycogen branching enzyme); Essential enzyme that catalyzes the formation of the alpha- 1,6-glucosidic linkages in glucan chains 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. Is involved in the biosynthesis of both glycogen and capsular alpha-D- glucan.
