β¦ Synopsis
Equine erythrocyte peptidases were compared to the six human erythrocyte peptidases, A, B, C, D, E, and F, regarding substrate specificity, relative activity, and electrophoretic mobility. Five equine erythrocyte peptidases appeared homologous to human peptidases A, B, D, E, and F. In contrast to human, equine peptidase C was absent in red cells, although it was weakly active in white cells. On the other hand, an equine peptidase, probably homologous to human peptidase S, was weakly active in red cells as well as present in white cells. Polymorphism for equine erythrocyte peptidase A is reported.

Gene dosage effect for the enzyme peptidase A was studied in the red cells of subjects trisomic (seven cases) or monosomic (five cases) for the segment of chromosome 18 carrying the gene. The individual levels of enzyme activity in both groups were differen from those of the controls, but with a wid
