Two forms of trehalase activity in mice.

M N Tenan, A D Panek, D R Malamud

    Anais Da Academia Brasileira De Ciencias
    |March 1, 1979
    PubMed
    Summary

    Researchers compared mouse serum and kidney trehalase activities using chromatography and electrophoresis. Distinct behaviors were observed, indicating at least two forms of the trehalase enzyme exist in mice.

    Area of Science:

    • Biochemistry
    • Enzymology
    • Mammalian Physiology

    Background:

    • Trehalase is a key enzyme involved in trehalose metabolism.
    • Understanding different trehalase forms is crucial for metabolic studies.
    • Previous research has not fully elucidated the distinct forms of trehalase in mice.

    Purpose of the Study:

    • To compare trehalase activities in mouse serum and kidney.
    • To determine if distinct molecular forms of trehalase exist in these tissues.
    • To characterize the biochemical properties of mouse trehalase isoforms.

    Main Methods:

    • Ion exchange chromatography (DEAE-cellulose and SP-Sephadex) was employed.
    • Polyacrylamide gel electrophoresis was used for separation and visualization.
    • Thermal lability assays were conducted to assess enzyme stability.

    Main Results:

    • Trehalase activities from serum and kidney exhibited distinct chromatographic behaviors.
    • Electrophoretic analysis revealed differences in migration patterns.
    • Thermal stability profiles differed between the two sources, confirming distinct properties.

    Conclusions:

    • The study provides evidence for at least two distinct molecular forms of trehalase in mice.
    • These findings suggest tissue-specific expression or post-translational modification of trehalase.
    • Further research is warranted to isolate and fully characterize these trehalase isoforms.
