In enzymology, an alpha,alpha-trehalose-phosphate synthase (GDP-forming) (EC 2.4.1.36) is an enzyme that catalyzes the chemical reaction
Thus, the two substrates of this enzyme are GDP-glucose and glucose 6-phosphate, whereas its two products are GDP and alpha,alpha'-trehalose 6-phosphate.
This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is GDP-glucose:D-glucose-6-phosphate 1-alpha-D-glucosyltransferase. Other names in common use include GDP-glucose-glucose-phosphate glucosyltransferase, guanosine diphosphoglucose-glucose phosphate glucosyltransferase, and trehalose phosphate synthase (GDP-forming).
Trehalose is a sugar consisting of two molecules of glucose. It is also known as mycose or tremalose. Some bacteria, fungi, plants and invertebrate animals synthesize it as a source of energy, and to survive freezing and lack of water.
Glycogenin is an enzyme involved in converting glucose to glycogen. It acts as a primer, by polymerizing the first few glucose molecules, after which other enzymes take over. It is a homodimer of 37-kDa subunits and is classified as a glycosyltransferase.

Sucrose-phosphate synthase (SPS) is a plant enzyme involved in sucrose biosynthesis. Specifically, this enzyme catalyzes the transfer of a hexosyl group from uridine diphosphate glucose (UDP-glucose) to D-fructose 6-phosphate to form UDP and D-sucrose-6-phosphate. This reversible step acts as the key regulatory control point in sucrose biosynthesis, and is an excellent example of various key enzyme regulation strategies such as allosteric control and reversible phosphorylation.
In enzymology, a trehalose 6-phosphate phosphorylase is an enzyme that catalyzes the chemical reaction
In enzymology, a glucose-1-phosphate guanylyltransferase is an enzyme that catalyzes the chemical reaction
