Applicazioni

Galacto-N-biose, a component of the galacto-N-biose/lacto-N-biose metabolic pathway, is used as a substrate to identify, differentiate and characterize enzymes such as N-acetylglucosaminyltransferase(s), fucosyl- and sialyltransferase(s), galactosidase(s) and galacto-N-biose/lacto-N-biose I phosphorylase(s) (GLNBP). Galacto-N-biose is used in lectin inhibition studies.

Substrati

A substrate for N-acetylglucosaminyltransferase, fucosyl- and sialyltransferase, and galactosidase. Also used in lectin inhibition studies.

We have examined the carbohydrate binding specificity of the B4 lectin from Vicia villosa seeds. The B4 lectin agglutinates Tn-exposed erythrocytes specifically and binds to these erythrocytes (1.4 X 10(6) sites/cell) with an association constant of 4.2 X 10(7) M-1.

Review of O-Linked Glycoproteins

O-Linked glycoproteins are usually large proteins with a molecular mass of >200 kDa. Glycosylation generally occurs in high-density clusters and may represent as much as 50-80% of the overall mass.
