allozyme

Genetics
A variant enzyme synthesised from a gene’s codominant alleles (at the same locus), which contrast to isoenzymes performing the same function but encoded by genes located elsewhere in the organism’s genome.

Molecular biology
One of the different forms of an enzyme found in individuals of the same species, due to the presence of multiple alleles in the population.

allozyme

(al′ŏ-zīm″) [ allo- + (en)zyme]
An enzyme that has small substitutions in its genetic coding and protein structure.

allozyme

a form of protein coded by a particular ALLELE at a single gene LOCUS that is detectable by ELECTROPHORESIS.

By means of cellulose acetate gel electrophoresis, wherein 8 allozyme loci (FUM, G6PDH, GOT, IDH, LDH, MPI, PGI, and PGM) were studied, we investigate whether the genetic variation among species is larger compared to the variation among populations within species and indicative of reproductive isolation among the species.
