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

glgAPutative 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 [...] (387 aa)    
Predicted Functional Partners:
glgC
Glucose-1-phosphate adenylyltransferase GlgC (ADP-glucose synthase) (ADP-glucose pyrophosphorylase); 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; Belongs to the bacterial/plant glucose-1-phosphate adenylyltransferase family.
 
 
 0.999
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 [...]
 
 0.998
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.

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.

glgP
Probable glycogen phosphorylase GlgP; Phosphorylase is an important allosteric enzyme in carbohydrate metabolism. Enzymes from different sources differ in their regulatory mechanisms and in their natural substrates. However, all known phosphorylases share catalytic and structural properties (By similarity).

treZ
Maltooligosyltrehalose trehalohydrolase TreZ; Is involved in the biosynthesis of trehalose but not in that of capsular glucan and glycogen.
