Sulfazyme_Logo_Black

The Sulfazyme™ (EC 3.1.6.1) product line of purified recombinant and genetically modified arylsulfatases is designed to hydrolyze select sulfated compounds at 37 °C. Sulfazyme hydrolyzes beta-linked sulfate ester groups from metabolites as part of phase II detoxification in the liver. Choose between the original Sulfazyme™ PaS for general sulfatase needs or any of our genetically modified variants for hydrolyzing recalcitrant steroid substrates such as dehydroepiandrosterone sulfate (DHEAS), boldenone sulfate, and testosterone sulfate. Consult the table below to learn more or sign up to test our next-generation sulfatase variants.

Sulfazyme™ is an excellent alternative to acid hydrolysis for the analysis of compounds that contain a sulfate ester moiety. Strong acid hydrolysis can lead to analyte degradation or increased matrix interference, thus artificially altering results1. Additionally, Sulfazyme™ can be paired with our beta-glucuronidase enzyme product to analyze both glucuronidated and sulfated metabolites simultaneously. Please contact us to learn more.

Sulfazyme PaS Black Logo Complete

Sulfazyme™ PaS (EC 3.1.6.1) is a purified recombinant aryl-sulfatase designed to hydrolyze select sulfated compounds at 37 °C. Sulfazyme hydrolyzes the sulfate groups from metabolites that have been sulfated as part of phase II detoxification in the liver.

Sulfazyme™ PaS hydrolyzes selected sulfated compounds with higher activity than other commercially available sulfatases.

The table below compares activity levels between Sulfazyme™ PaS and other sulfatases available on the market today. Activity levels for other sulfatases were derived from data found in the literature.1

Why use Sulfazyme™ PaS?

The majority of commercially available sulfatase enzymes are sourced from organisms like snails, limpets, or abalone, which may contain interfering metabolites and enzymatic activities that can lead to inaccurate results. Sulfazyme™ PaS is recombinant and has >90% purity. This enzyme has been shown to exclusively exhibit sulfatase activity, ensuring highly specific and accurate hydrolysis.

Relative activity was determined by normalizing against the lowest activity.

Another study compared the deconjugation efficiencies of three enzymes for hydrolyzing terbutaline metabolites in human urine samples. IMCSzyme® and Sulfazyme™ PaS (referred to as IMCS-PSF in the article) were compared to Helix pomatia β-glucuronidase (Sigma). Urine samples from healthy volunteers were collected before and after oral administration of terbutaline tablets. Samples were subjected to four enzyme and sample mixture conditions (Table 1). This study demonstrated that Sulfazyme™ PaS shows higher hydrolysis efficiency than other enzymes typically used for the analysis of terbutaline (Figure 3).

When used in conjunction with IMCSzyme®, Sulfazyme facilitates faster and more efficient discoveries of conjugated metabolites which would be otherwise difficult to detect by mass spectrometry.

Combining IMCSzyme and Sulfazyme PaS below enables the rapid detection of phenyl-γ-valerolactones (PVLs) in urine. The traditional method requires 6 hours while hydrolysis with the combined IMCSzyme and Sulfazyme enzymes requires only 30 minutes.2

Using IMCSzyme beta-glucuronidase alongside Sulfazyme PaS enables the rapid hydrolysis of PVLs
