A full-length cDNA clone for mouse N-acetylglucosamine (beta 1-4)galactosyltransferase (beta 1-4GT) [EC 2.4.1.90] and several clones diverged from the beta 1-4GT cDNA were isolated from a mouse F9 cDNA library and then sequenced. The beta 1-4GT cDNA has an open reading frame consisting of 399 amino acids. The homology at the amino acid level is 80 and 91% as to the partial sequences of bovine and human milk beta 1-4GT, respectively. The general enzyme structure of the beta 1-4GT seems to be similar to that of a rat beta-galactoside (alpha 2-6) sialyltransferase. Junctions of the common and divergent regions of cDNA have dinucleotides, AG, suggesting that the variety of cDNA clones is generated through alternative splicing.

UI	MeSH Term	Description	Entries
D007788	Lactose Synthase	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.

D003001	Cloning, Molecular	The insertion of recombinant DNA molecules from prokaryotic and/or eukaryotic sources into a replicating vehicle, such as a plasmid or virus vector, and the introduction of the resultant hybrid molecules into recipient cells without altering the viability of those cells.	Molecular Cloning
D004247	DNA	A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).
