Preferred Label : lactose synthase;
MeSH definition : 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.;
MeSH synonym : lactose synthetase; synthase, lactose; synthetase, lactose;
MeSH hyponym : N-Acetylgucosamide 1-4 beta galactosyl transferase; N Acetylgucosamide 1 4 beta Galactosyl Transferase;
MeSH CAS label : UDPgalactose:D-glucose 4-beta-D-galactosyltransferase;
MeSH Related Number : 9030-11-9 (CAS RN);
Registry Number MeSH : EC 2.4.1.22;
Is substance : O;
UNII : EC 2.4.1.22;
Origin ID : D007788;
