  • Title: [Esterase polymorphism and heat resistance of the interphalangeal muscle of the common frog].
    Author: Kesamanly NV.
    Journal: Tsitologiia; 1982 Nov; 24(11):1353-7. PubMed ID: 6984247.
    Abstract:
    A study has been made of the electrophoretic esterase spectrum of m. interphalangealis of the grass frog and the heat resistance of this muscle. Vertical electrophoresiss in polyacrilamid gel revealed the enzyme polymorphism in the zone of high electrophoretic mobility. In zone Est.-2, two esterase isoenzymes were detected which was assumed to be the site of genetic control of one locus with two codominant alleles. It is shown that under the standard environmental conditions, there exists a relation between the presence of esterase isoenzymes in m. interphalangealis and the heat resistance of this muscle: the isoenzyme of the slow esterase is present in highly resistant muscles, both isoenzymes are present in muscle with the average resistance level, and the isoenzyme of quick esterase occurs in muscles with different levels of resistance.
