Entry terms

  • Lactose Synthetase
  • Synthetase, Lactose

Scope note

  • An enzyme complex that catalyzes the transfer of GALACTOSE from UDP GALACTOSE to GLUCOSE, forming LACTOSE. The enzyme complex is composed of a B subunit, ALPHA-LACTALBUMIN, which changes the substrate specificity of the A subunit, N-ACETYLLACTOSAMINE SYNTHASE, from N-ACETYLGLUCOSAMINE to glucose making lactose synthesis the preferred reaction.

History note

  • 92: was LACTOSE SYNTHETASE 1972-91 (Prov 1972-73)
