β-Galactosidase from Escherichia coli

Poids moléculaire du tétramère : 465 kDa (chaque sous-unité ayant 116,3 kDa)

β-galactosidase is a 465 kDa tetrameric protein. It is coded by the LacZ gene.

β-Galactosidase may be used for derivatization, such as an enzyme label for IgG, without prior dialysis or gel filtration.

β-Galactosidase from Escherichia coli has been used to produce biocatalytic Ca-alginate beads on a B-390 encapsulator (BUCHI). It has been used to prepare the source droplet solution and also as the cargo for Pep-1 (KETWWETWWTEWSQPKKKRKV-cysteamide).

βLa β-galactosidase clive le lactose en ses constituants monosaccharides, le glucose et le galactose. Elle catalyse également la transglycosylation du glucose en allolactose, inducteur de la β-galactosidase, dans une boucle de rétroaction.

β-galactosidase is considered as a reporter enzyme in applications involving gene expression regulation, analysis of protein function/structure and target gene expression.
