Product Specs

Introduction
Arylsulfatase A, also known as ARSA, plays a crucial role in breaking down cerebroside sulfate into cerebroside and sulfate. This enzyme's activity is hindered by phosphate, which forms a covalent bond with the active site's 3-oxoalanine. Genetic defects affecting the ARSA gene lead to metachromatic leukodystrophy (MLD). MLD is a progressive neurological disorder characterized by the deterioration of the myelin sheath, resulting in a range of neurological issues and ultimately death.
Description

Recombinant ARSA Mouse protein, expressed in Sf9 cells, is a single, glycosylated polypeptide chain consisting of 498 amino acids (positions 18-506), with a molecular mass of 53.2 kDa. It's important to note that on SDS-PAGE, the apparent molecular size might range from 50 to 70 kDa. The ARSA Mouse protein includes a 9-amino acid His-Tag fused at its C-terminus and is purified using proprietary chromatographic techniques.

Physical Appearance
The product appears as a clear solution that has been sterilized through filtration.
Formulation

The ARSA protein solution is provided at a concentration of 0.5 mg/ml. It is formulated in a solution of Phosphate Buffered Saline (pH 7.4) containing 10% glycerol.

Stability
For short-term storage (2-4 weeks), keep the product refrigerated at 4°C. For extended storage, freeze the product at -20°C. Adding a carrier protein such as HSA or BSA (0.1%) is advised for long-term storage. It's essential to avoid repeated freeze-thaw cycles.
Purity
The purity of the ARSA protein is determined to be greater than 95% through SDS-PAGE analysis.

Product Science Overview

Definition and Classification

Arylsulfatase A (ARSA), also known as cerebroside-sulfatase, is an enzyme that hydrolyzes cerebroside sulfate into cerebroside and sulfate . In the context of recombinant proteins, Mouse Recombinant Arylsulfatase A refers to the ARSA enzyme produced using recombinant DNA technology in a mouse cell line .

Biological Properties and Functions

ARSA plays a crucial role in the degradation of sulfatides, which are essential components of the myelin sheath in the nervous system . The enzyme’s activity is vital for maintaining the normal function of the nervous system. Deficiency in ARSA activity leads to the accumulation of sulfatides, causing a lysosomal storage disorder known as metachromatic leukodystrophy (MLD) .

Mode of Action

The enzyme ARSA hydrolyzes the sulfate ester bond in cerebroside sulfate, converting it into cerebroside and sulfate . This reaction is essential for the catabolism of sulfatides in the lysosomes. The enzyme’s activity is measured by its ability to hydrolyze synthetic substrates such as 4-Nitrocatechol Sulfate (PNCS) .

Recombinant Production

Recombinant Mouse Arylsulfatase A is produced in mouse myeloma cell lines (NS0) or Sf9 Baculovirus cells . The recombinant protein typically includes a signal peptide and a mature chain, with a molecular mass of approximately 54 kDa . It is often tagged with a His-tag for purification purposes .

Regulatory Mechanisms

ARSA activity is regulated by various factors, including the presence of phosphate, which can inhibit the enzyme by forming a covalent bond with the active site . Additionally, the enzyme’s stability and activity can be influenced by the formulation and storage conditions .

Applications and Research

Recombinant Mouse Arylsulfatase A is used in various research applications, including studies on lysosomal storage disorders, enzyme replacement therapies, and the biochemical pathways involving sulfatides . Its activity and stability make it a valuable tool for understanding the molecular mechanisms underlying MLD and other related diseases.
