    Summary
    This summary is machine-generated.

    Human saliva esterases were identified using zymography, revealing three phenotypes. Genetic analysis indicates these are carboxylesterases controlled by an autosomal locus with two alleles, Set-1F and Set-1S.

    Area of Science:

    • Biochemistry
    • Human Genetics
    • Enzymology

    Background:

    • Esterases are enzymes that hydrolyze ester bonds.
    • Human saliva contains various esterase enzymes.
    • Understanding esterase genetics is crucial for population studies.

    Purpose of the Study:

    • To identify and characterize esterases present in human saliva.
    • To investigate the genetic basis of observed esterase phenotypes.
    • To determine the specific type of esterases found in region 1.

    Main Methods:

    • Zymogram technique was employed to visualize esterase activity.
    • Phenotypic analysis was conducted on saliva samples.
    • Family and population studies were performed to assess inheritance patterns.

    Main Results:

    • Three distinct esterase phenotypes were identified in region 1.
    • These phenotypes are determined by an autosomal locus.
    • The locus has two alleles, designated Set-1F and Set-1S.
    • The identified esterases in region 1 are carboxylesterases.

    Conclusions:

    • Human saliva esterases exhibit genetic polymorphism.
    • The Set-1 locus controls the expression of salivary carboxylesterases.
    • These findings contribute to understanding human enzyme variation.
