Aplicación
Citrate Synthase from porcine heart has been used:
- to inject newt egg for determining its importance in egg activation at fertilization[1]
- in the preparation of reaction mix to determine pyruvate carboxylase enzyme activity[2]
- to examine whether it can induce a [Ca2+] increase and egg activation in unfertilized eggs[3]
Acciones bioquímicas o fisiológicas
Citrate synthase catalyses the conversion of citrate to acetyl-CoA in the presence of coenzyme-A with the release of H2O and oxaloacetate. The enzyme has a molecular weight of 85 kDa and a pI of 6.1-6.6. It is inhibited by fluoroacetyl-CoA, palmitoyl-CoA, and citroyl-CoA. It is also inhibited when it is acetylated by acetic anhydride or iodinated by iodine.
Definición de unidad
One unit will form 1.0 μmole of citrate from oxalacetate and acetyl CoA per min at pH 8.0 at 37 °C.
Forma física
Suspension in 3.2 M (NH4)2SO4 solution, pH 7.0.
Nota de preparación
Dissolves in water to form a clear solution at 1 mg/mL concentration.

A recently discovered group of conditionally disordered chaperones share a very unique feature; they need to lose structure to become active as chaperones. This activation mechanism makes these chaperones particularly suited to respond to protein-unfolding stress conditions, such as oxidative
