Lactoglobulin

(Swiss-Prot ID P02754)
  • Function: Lactoglobulin is a primary component of whey, it binds retinol and is probably involved in the transport of that molecule.

Sialyltransferase St8Sia IV

(Swiss-Prot ID Q92187)
  • Function: Sialyltransferase St8Sia IV catalyzes the polycondensation of alpha-2,8-linked sialic acid required for the synthesis of polysialic acid (PSA), which is present on the embryonic neural cell adhesion molecule (N-CAM), necessary for plasticity of neural cells.

Lysozyme C

(Swiss-Prot ID P00698)
  • Function: Lysozymes have primarily a bacteriolytic function; those in tissues and body fluids are associated with the monocyte-macrophage system and enhance the activity of immunoagents.

Fucosyltransferase 3

(Swiss-Prot ID P21217)
  • Function: Fucosyltransferase 3 may catalyze alpha-1,3 and alpha-1,4 glycosidic linkages involved in the expression of Vim-2, Lewis A, Lewis B, sialyl Lewis X and Lewis X/SSEA-1 antigens. May be involved in blood group Lewis determination; Lewis-positive (Le+) individuals have an active enzyme while Lewis-negative (Le-) individuals have an inactive enzyme.

Beta-1,4-galactosyltransferase 1

(Swiss-Prot ID P08037)
  • Function: Beta-1,4-galactosyltransferase catalyzes the production of lactose in the lactating mammary gland and could also be responsible for the synthesis of complex-type N-linked oligosaccharides in many glycoproteins as well as the carbohydrate moieties of glycolipids (Golgi complex form). The cell surface form functions as a recognition molecule during a variety of cell to cell and cell to matrix interactions, as those occurring during development and egg fertilization, by binding to specific oligosaccharide ligands on opposing cells or in the extracellular matrix.

Aspartoacylase

(Swiss-Prot ID Q9R1T5)
  • Function: Aspartoacylase Catalyzes the deacetylation of N-acetylaspartic acid (NAA) to produce acetate and L-aspartate. NAA occurs in high concentration in brain and its hydrolysis NAA plays a significant part in the maintenance of intact white matter.
