Lactose synthesis rate is an important factor in milk production and quality in mammals. Understanding the lactose synthesis mechanism is crucial for the improvement of milk quantity and quality. However, research on the temporal gene changes regarding lactose synthesis during the whole lactation is still limited. The objective of this study was to determine gene expression profiles related to lactose synthesis in sows during lactation, and further identify the critical steps or key factors in the lactose synthesis pathway. To determine the temporal change of factors related to lactose synthesis in sows, milk from eight multiparous Yorkshire sows (parity 3 to 6) was collected at 0 h, 2 h, 6 h, 12 h, 24 h, day 2, 3, 4, 7, 14, and 21 after birth of the first piglet. Lactose content, prolactin and progesterone concentration, and gene or protein expression related to lactose synthesis were measured. The lactose yield increased gradually from D2 to D21 and reached a maximum at D14 (3-fold from D2) during

The inhibition of lactose synthetase A protein by p-hydroxymercuribenzoate at pH7.5 and 25°C, which involves the reaction of one molecule of inhibitor with each molecule of enzyme, was decreased in rate by UDP-galactose, especially in the presence of Mn2+. Pseudo-first-order rate constants for the reaction between 0.1mm-p-hydroxymercuribenzoate and free enzyme, the enzyme-UDP-galactose complex and the enzyme-Mn2+-UDP-galactose complex were 4.4×10−2, 1.9×10−2 and 0.3×10−2min−1 respectively. The results also indicated that dissociation constants for UDP-galactose in the enzyme-UDP-galactose and enzyme-Mn2+-UDP-galactose complexes were 313 and 16μm respectively, the latter value being similar to the Km for UDP-galactose in the lactose synthetase reaction. The protective effect of UDP-galactose and the role of Mn2+ ions in lactose synthetase are discussed.. ...

LALBA Full-Length MS Protein Standard (NP_002280), Labeled with [U- 13C6, 15N4]-L-Arginine and [U- 13C6, 15N2]-L-Lysine, was produced in human 293 cells (HEK293) with fully chemically defined cell culture medium to obtain incorporation efficiency at Creative-Proteomics. This gene encodes alpha-lactalbumin, a principal protein of milk. Alpha-lactalbumin forms the regulatory subunit of the lactose synthase (LS) heterodimer and beta 1,4-galactosyltransferase (beta4Gal-T1) forms the catalytic component. Together, these proteins enable LS to produce lactose by transfering galactose moieties to glucose. As a monomer, alpha-lactalbumin strongly binds calcium and zinc ions and may possess bactericidal or antitumor activity. A folding variant of alpha-lactalbumin, called HAMLET, likely induces apoptosis in tumor and immature cells.

lactose synthase (EC 2.4.1.22); β-N-acetylglucosaminyl-glycopeptide β-1,4-galactosyltransferase (EC 2.4.1.38); N-acetyllactosamine synthase (EC 2.4.1.90); xylosylprotein β-4-galactosyltransferase (EC 2.4.1.133); UDP-Gal: neolactotriaosylceramide β-1,4-galactosyltransferase (EC 2.4.1.275); β-1,4-N-acetylglucosaminyltransferase (EC 2.4.1.- ...

2-hydroxyacylsphingosine 1-beta-galactosyltransferase (541 aa, ~61 kDa) is encoded by the human UGT8 gene. This protein is involved in the transfer of galactose to ceramide.

The biosynthesis of disaccharides, oligosaccharides and polysaccharides involves the action of hundreds of different glycosyltransferases. These enzymes catalyse the transfer of sugar moieties from activated donor molecules to specific acceptor molecules, forming glycosidic bonds. A classification of glycosyltransferases using nucleotide diphospho-sugar, nucleotide monophospho-sugar and sugar phosphates (EC 2.4.1.-) and related proteins into distinct sequence based families has been described [(PUBMED:9334165)]. This classification is available on the CAZy (CArbohydrate-Active EnZymes) web site. The same three-dimensional fold is expected to occur within each of the families. Because 3-D structures are better conserved than sequences, several of the families defined on the basis of sequence similarities may have similar 3-D structures and therefore form clans.. Glycosyltransferase family 28 comprises enzymes with a number of known activities; 1,2-diacylglycerol 3-beta-galactosyltransferase (EC ...
