  1. Lactose synthase

    Lactose synthase is an enzyme that generates lactose from glucose and UDP-galactose. It is classified under EC It consists of N-acetyllactosamine synthase and alpha-lactalbumin. Alpha-lactalbumin, which is expressed in response to prolactin, increases the affinity of N-acetyllactosamine synthase for its substrate, causing increased production of lactose during lactation.

  1. Lactose Synthase

    An enzyme of the transferase class that catalyzes the transfer of galactose from UDPgalactose to glucose, forming lactose. The enzyme is a complex of the enzyme N-ACETYLLACTOSAMINE SYNTHASE and alpha-lactalbumin; the latter protein is present in lactating mammary gland cells where it alters the usual specificity of the former to make lactose synthesis the preferred reaction. (Dorland, 28th ed) EC
