Purity: > 90% by SDS - PAGE Format: Liquid. 20mM Tris-HCl buffer (pH8.0) containing 20% glycerol, 0.1M NaCl, 1mM DTT . ACYP1, also known as erythrocyte acylphosphatase, is a cytosolic enzyme that catalyzes the hydrolysis of the carboxyl-phosphate bond of acylphosphates. Two acylphophatase isoenzymes exist: ACYP1 and ACYP2. The two isoenzymes share 60% homology and have the same substrate specificity, although ACYP1 has higher catalytic activity than ACYP2. Recombinant human ACYP1 protein, fused to His-tag at N-terminus, was expressed in E.coli and purified by using conventional chromatography.
