Natural hybrid zones involving the West Indian pulmonate land snail Cerion are characterized by the occurrence, in low to moderate frequencies, of allozymes that are unique to interspecific hybrid zones. As such electrophoretically detected genetic anomalies havr also becn reported in hybrid zones involving mammals, birds, reptiles, amphibians, and insects this appears to be a general phenomeno...

Sulfotransferases (SULTs) are enzymes involved in phase II of the metabolism xenobiotics. Single nucleotide polymorphisms were identified for genes encoding SULTs leading to allozymes with modified sulfating activity. This study aims analyze effects most frequently amino acid mutations sequences belonging SULT1 family on their local properties and structural stability. The outcomes reveal that ...

Spatial genetic variation was assessed in the common house fly Musca domestica. Allozymes at three gene enzyme system unraveled ten loci which revealed seventeen alleles in house fly populations. F statistics revealed that except ACPH-1 and EST-3 all the other loci show inbreeding (Fis>Fst). Persistent heterozygosity was observed in ACPH-1(Fis= -0.140) which indicate random mating for this locus.

Sulfotransferase 1A1 (SULT1A1) (thermostable phenol sulfotransferase, TS PST1, P-PST) is important in the metabolism of thyroid hormones. SULT1A1 isolated from human platelets displays wide individual variations not only in the levels of activity, but also in thermal stability. The activity of the allelic variant or allozyme SULT1A1*1, which possesses an arginine at amino acid position 213 (Arg...
