title: [2 new esterase loci Es-14 and Es-15 in mice (genus Muc L.) : characterization by different substrates and inhibitors].
abstract: Allelic differences at an esterase locus designated Es-14 exist between Mus musculus (both inbred strains and wild Mice) and Mus spretus. This locus is expressed in a variety of tissues. Mus musculus has been assigned the allele Es-14r while Mus spretus carries the alternate alleles Es-14l. Each phenotype manifests itself as a single band of enzyme activity and F1 hybrids show two bands corresponding to the parental forms. Allozyme variation was also detected at another esterase locus, temporarily disignated as Es-15 until confirmed by current linkage analysis. A slow variant Es-15 was recorded in a Mus musculus population from Greece while inbred strains carry the Es-15m allele. Study of a Mus spicilegus population from Greece revealed the presence of a third allele, Es-15r. Substrate and inhibition characteristics are provided for both loci.
