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.

treYMaltooligosyltrehalose synthase TreY; Catalyzes the conversion of maltooligosaccharide into the non-reducing saccharide, maltooligosyl trehalose (alpha-maltooligosyl alpha-D-glucoside) by intramolecular transglycosylation. (765 aa)    
Predicted Functional Partners:
treZ
Maltooligosyltrehalose trehalohydrolase TreZ; Is involved in the biosynthesis of trehalose but not in that of capsular glucan and glycogen.

treX
Rv1564c, (MTCY48.01), len: 721 aa. Probable treX (previously called glgX), Maltooligosyltrehalose synthase. Strong similarity to D83245|g1890053 treX, glycogen debranching enzyme (glgX) from Sulfolobus acidocaldarius (713 aa), FASTA score: opt: 2396, E(): 0, (48.4% identity in 709 aa overlap); similar to GLGX_HAEIN|P45178 glycogen operon protein glgx (659 aa), FASTA scores: opt: 1512, E(): 0, (42.3% identity in 645 aa overlap); Belongs to the glycosyl hydrolase 13 family.

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 [...]

malQ
Probable 4-alpha-glucanotransferase MalQ (amylomaltase) (disproportionating enzyme) (D-enzyme); Rv1781c, (MTV049.03c), len: 724 aa. Probable malQ,4-alpha-glucanotransferase, similar to many, e.g. P15977|MALQ_ECOLI 4-alpha-glucanotransferase (694 aa),FASTA scores: opt: 964, E(): 0, (31.8% identity in 694 aa overlap). Belongs to the disproportionating enzyme family.

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 [...]

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 [...]

otsB2
Trehalose 6-phosphate phosphatase OtsB2 (trehalose-phosphatase) (TPP); Removes the phosphate from trehalose 6-phosphate to produce free trehalose.

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.

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).

glgA
Putative glycosyl transferase GlgA; Involved in the biosynthesis of the maltose-1-phosphate (M1P) building block required for alpha-glucan production by the key enzyme GlgE. Catalyzes the formation of an alpha-1,4 linkage between glucose from ADP-glucose and glucose 1- phosphate (G1P) to yield maltose-1-phosphate (M1P). Also able to catalyze the elongation of the non-reducing ends of glycogen, maltodextrin and maltoheptaose using ADP-glucose as sugar donor, however the rate of the reaction appears to be too low to be physiologically relevant. GlgM is also able to use UDP-glucose as sug [...]
