beta-Mannosidase in human serum and urine. A comparative study.
The International Journal of Biochemistry
|January 1, 1986
Summary
Serum and urine beta-mannosidase enzymes were purified using DEAE-Trisacryl chromatography. Both enzymes showed similar properties, with minor variations in thermostability and molecular weight.
Area of Science:
- Biochemistry
- Enzymology
Background:
- Beta-mannosidase is a key enzyme involved in glycoprotein metabolism.
- Deficiency in beta-mannosidase activity is linked to genetic disorders.
Purpose of the Study:
- To isolate and characterize beta-mannosidase from human serum and urine.
- To compare the properties of serum and urine beta-mannosidase.
Main Methods:
- Ion-exchange chromatography using DEAE-Trisacryl.
- Sodium chloride (NaCl) linear gradient elution.
- Analysis of enzyme properties including thermostability and molecular weight.
Main Results:
- Beta-mannosidase from both serum and urine adsorbed to DEAE-Trisacryl at pH 6.
- A single form of the enzyme was eluted from the column.
- The isolated enzymes exhibited similar biochemical properties.
- Minor differences were noted in thermostability and molecular weight.
Conclusions:
- Serum and urine beta-mannosidase are biochemically similar, suggesting a common origin or function.
- These findings contribute to understanding beta-mannosidase enzymology and its potential role in disease diagnostics.
