Enzymes for Research, Diagnostic and Industrial Use

Biotinylated Transglutaminase from Human, Proenzyme (Zymogen)


Cat No.
NATE-1735
Description
This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing groups (phosphotransferases) with a phosphate group as acceptor.
Abbr
TG 3, Recombinant (Human)
Alias
TG3
Source
E. coli
Species
Human
Applications
The transglutaminase 3 catalyzes acyl transfer reactions from glutamin residues in proteins or peptides to primary amines, e. g. the formation of ε-(γ-glutamyl) lysine bonds between proteins by transferring the acyl group of a peptide-bound glutamine residue to the primary amino group of a peptide-bound lysine residue. Biotinylated transglutaminase 3 may also be used for immunoprecipitation.
Appearance
Liquid
Package
100 µg
Form
The transglutaminase is formulated in 10 mM Sodium Phosphate pH 8.0, 15 mM NaCl.
Sample contains 50% glycerol. Transglutaminase is a Ca2+-dependent enzyme.
Enzyme Commission Number
EC 2.3.2.13
Activity
> 1000 U/mg [Activity is determined by measuring the rate of fluorescence enhancement after transglutaminase-catalyzed monodansylcadaverine-incorporation into N,N-dimethylated casein according to Lorand et al., Anal. Biochem. 44 (221-231)].
CAS No.
80146-85-6
Molecular Weight
78 kDa
Purity
> 95 % (visually by SDS-PAGE)
Unit Definition
1 U is defined as the increase in fluorescence intensity of 1 a.u./min (measured on a Cary eclipse fluorescence spectrophotometer, Varian; λex = 332 nm, λem = 500 nm; band filter = 5 nm; detector strength = 600 V; temperature = 37 °C, assay volume = 1 ml).
Activators
10 μl His6-rhTG3 (1 μg/μl)
35 μl 50 mM Tris-HCl pH 8
5 μl Dispase I (Roche) (0.2 μg/μl)
Incubate for 20 min at 30 °C
Add 10 mM Ca2+ to activate transglutaminase3.
Storage
Store at -20 °C in working aliquots. Repeated freezing and thawing is not recommended.
