| α-1,2-colitosyltransferase | The enzyme, characterized from the bacterium Escherichia coli O55:H7, participates in the biosynthesis of an O-antigen. The reaction involves anomeric inversion, and does not require any metal ions. The enzyme is highly specific towards the acceptor, exclusively recognizing lacto-N-biose, but can accept GDP-L-fucose as the donor with almost the same activity as with GDP-β-L-colitose. Group: Enzymes. Synonyms: wbgN (gene name). Enzyme Commission Number: EC 2.4.1.341. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C. Form: Liquid or lyophilized powder. EXWM-2580; α-1,2-colitosyltransferase; EC 2.4.1.341; wbgN (gene name). Cat No: EXWM-2580. | |
| lacto-N-biosidase | The enzyme from Streptomyces specifically hydrolyses the terminal lacto-N-biosyl residue (β-D-Gal-(1?3)-D-GlcNAc) from the non-reducing end of oligosaccharides with the structure β-D-Gal-(1?3)-β-D-GlcNAc-(1?3)-β-D-Gal-(1?R). Lacto-N-hexaose (β-D-Gal-(1?3)-β-D-GlcNAc-(1?3)-β-D-Gal-(1?3)-β-D-GlcNAc-(1?3)-β-D-Gal-(1?4)-D-Glc) is hydrolysed to form first lacto-N-tetraose plus lacto-N-biose, with the subsequent formation of lactose. Oligosaccharides in which the non-reducing terminal Gal or the penultimate GlcNAc are replaced by fucose or sialic acid are not substrates. Asialo GM1 tetraose (β-D-Gal-(1?3)-β-D-GalNAc-(1?3)-β-D-Gal-(1?4)-D-Glc) is hydrolysed very slowly, but lacto-N-neotetraose (β-D-Gal-(1?4)-β-D-GalNAc-(1?3)-β-D-Gal-(1?4)-D-Glc) is not a substrate. Group: Enzymes. Enzyme Commission Number: EC 3.2.1.140. CAS No. 146359-52-6. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C. Form: Liquid or lyophilized powder. EXWM-3823; lacto-N-biosidase; EC 3.2.1.140; 146359-52-6. Cat No: EXWM-3823. | |
| Lacto-N-Biosidase, Recombinant | Lacto-N-Biosidase may be used during glycoprotein analysis to better study the structure and function of glycoprotein and glycolipid sugar chains. This product can be used for specific oligosaccharide hydrolysis of type-I chain oligosaccharides, producing lacto-N-biose (Gal β 1-3 GlcNAc) as a byproduct, but not oligosaccharide hydrolysis of type-II chain oligosaccharides. As a result, Lacto-N-Biosidase can be used to distinguish type-I versus type-II glycoprotein as well as glycolipid sugar chains. When used in conjunction with α -1,3/4-Fucosidase, Lacto-N-Biosidase can also help distinguish Sialyl-Lewis x and Sialyl-Lewis a structures. Applications: Specific hydrolysis of oligosaccharides with type-i sugar chains and production of byproduct lacto-n-biose (gal β 1-3 glcnac). Group: Enzymes. Synonyms: Oligosaccharide lacto-N-biosylhydrolase; Lacto-N-Biosidase. Lacto-N-Biosidase. Mole weight: 60 kDa (SDS-PAGE). Form: Solution in 50 mM sodium acetate buffer, pH 5.5, containing 0.05% Brij-58. Source: Streptomyces sp. 142. Oligosaccharide lacto-N-biosylhydrolase; Lacto-N-Biosidase. Cat No: NATE-0855. | |
| N-acetylhexosamine 1-kinase | This enzyme is involved in the lacto-N-biose I/galacto-N-biosedegradation pathway in the probiotic bacterium Bifidobacterium longum. Differs from EC 2.7.1.157, N-acetylgalactosamine kinase, as it can phosphorylate both N-acetylgalactosamine and N-acetylglucosamine at similar rates. Also has some activity with N-acetyl-D-mannosamine, D-talose and D-mannose as substrate. ATP can be replaced by GTP or ITP but with decreased enzyme activity. Requires a divalent cation, with Mg2+ resulting in by far the greatest stimulation of enzyme activity. Group: Enzymes. Synonyms: NahK; LnpB; N-acetylgalactosamine/N-acetylglucosamine 1-kinase. Enzyme Commission Number: EC 2.7.1.162. N-Acetylhexosamine 1-Kinase. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C. Form: Liquid or lyophilized powder. EXWM-2992; N-acetylhexosamine 1-kinase; EC 2.7.1.162; NahK; LnpB; N-acetylgalactosamine/N-acetylglucosamine 1-kinase. Cat No: EXWM-2992. | |
| N-acetylhexosamine 1-kinase from Bifidobacterium longum, Recombinant | N-acetylhexosamine 1-kinase (EC 2.7.1.162, NahK, LnpB, N-acetylgalactosamine/N-acetylglucosamine 1-kinase) is an enzyme with systematic name ATP:N-acetyl-D-hexosamine 1-phosphotransferase. This enzyme catalyses the following chemical reaction: ATP + N-acetyl-D-hexosamine ? ADP + N-acetyl-alpha-D-hexosamine 1-phosphate. This enzyme is involved in the lacto-N-biose I/galacto-N-biose degradation pathway in the probiotic bacterium Bifidobacterium longum. Group: Enzymes. Synonyms: EC 2.7.1.162; NahK; LnpB; N-acetylgalactosamine/N-acetylglucosamine 1-kinase; ATP:N-acetyl-D-hexosamine 1-phosphotransferase. Enzyme Commission Number: EC 2.7.1.162. Purity: min 95% by SDS-PAGE. N-Acetylhexosamine 1-Kinase. Mole weight: 40 kDa. Source: E. coli. Species: Bifidobacterium longum. N-acetylhexosamine 1-kinase; EC 2.7.1.162; NahK; LnpB; N-acetylgalactosamine/N-acetylglucosamine 1-kinase; ATP:N-acetyl-D-hexosamine 1-phosphotransferase. Cat No: NATE-1481. | |
