Enzymes for Research, Diagnostic and Industrial Use

Transglutaminase 4 from Human prostate, Recombinant

Cat No.
NATE-1736
Description
This enzyme is based on clone IMAGp958A10818Q2. It is N-terminally fused to a hexahistidine-tag resulting in the encoded N-terminal amino acid sequence MHHHHHHAEELLL…. This enzyme is produced in E. coli and purified by ion metal chelating chromatography to more than 95 % purity.
Abbr
TG 4, Recombinant (Human)
Alias
TG4
Source
E. coli
Species
Human
Applications
The transglutaminase 4 catalyzes acyl transfer reactions from glutamine 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. The transglutaminase 4 may also be used for immunoprecipitation.
Appearance
White lyophilized solid.
Package
100 µg
Form
The transglutaminase is lyophilized from 10 mM Tris-HCl pH 8.1, 150 mM NaCl, 5 mM DTT, 1 mM EDTA. Sample contains maltodextrin.
Enzyme Commission Number
EC 2.3.2.13
Activity
> 30 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
Add 10 mM Ca2+ to activate transglutaminase.
Storage
Store at -20 °C in working aliquots. Repeated freezing and thawing is not recommended.
Delivery is possible at ambient temperature.
Synonyms
transglutaminase; EC 2.3.2.13; 80146-85-6; transglutaminase; Factor XIIIa; fibrinoligase; fibrin stabilizing factor; glutaminylpeptide γ-glutamyltransferase; polyamine transglutaminase; tissue transglutaminase; R-glutaminyl-peptide:amine γ-glutamyl transferase; protein-glutamine γ-glutamyltransferase; TG1
Reconstitution
Add the volume of H2O the protein is lyophilized from to the vial of lyophilized powder. Rotate vial gently until solid dissolves. After reconstitution the solution should be stored frozen in working aliquots. Keep cooled on ice for short term storage.
