A new class EC 7, Translocases, has been added to the EC list. It will be part of ENZYME from release 2018_10. Read more about EC 7 here.

ENZYME entry: EC 2.4.1.245

Accepted Name
Alpha,alpha-trehalose synthase.
Alternative Name(s)
Trehalose synthase.
Trehalose synthetase.
Reaction catalysed
NDP-alpha-D-glucose + D-glucose <=> alpha,alpha-trehalose + NDP
Cofactor(s)
Mg(2+).
Comment(s)
  • The enzyme-catalyzed reaction is reversible.
  • In the reverse direction to that shown above, the enzyme is specific for alpha,alpha-trehalose as substrate, as it cannot use alpha- or beta-paranitrophenyl glucosides, maltose, sucrose, lactose or cellobiose.
  • While the enzymes from the thermophilic bacterium Rubrobacter xylanophilus and the hyperthermophilic archaeon Pyrococcus horikoshii can use ADP-, UDP- and GDP-alpha-D-glucose to the same extent, that from the hyperthermophilic archaeon Thermococcus litoralis has a marked preference for ADP-alpha-D-glucose and that from the hyperthermophilic archaeon Thermoproteus tenax has a marked preference for UDP-alpha-D-glucose.
  • Formerly EC 2.4.1.n1.
