  • Title: Purification of cobalt-activated acylase by affinity chromatography.
    Author: Słowińska R, Szewczuk A.
    Journal: Acta Biochim Pol; 1979; 26(3):229-48. PubMed ID: 573948.
    Abstract:
    alpha-Hydroxyisocaproyltyrosine (HyIc-Tyr-OH), a potent competitive inhibitor of the cobalt-activated acylase form 2, was synthesized. Its derivative, alpha-aminopentyl-HyIc-Tyr-OEt was coupled to cyanogen bromide-activated Sepharose 4B and was used for about 100-fold purification of the acylase from human liver by affinity chromatography. The preparation obtained did not show aminoacylase, aspartyl acylase or alanylarylamidase activities. The same chromatographic method was also applied to isolate form 2 of the serum acylase from patients with viral hepatitis and guinea pig placenta.
