Abstract
A survey of 37 inbred strains for erythrocyte purine nucleoside phosphorylase activity showed a greater than threefold range. Six of these strains had significantly greater activity than the others, and all of the high-activity strains had the Np-2 electrophoretic band. The high-purine nucleoside phosphorylase activity trait corresponding to Np-2 was inherited in an autosomal codominant manner and minor differences were apparent in thermal and kinetic properties between low- and high-activity strains. This work provides further support for there being either two structural loci for purine nucleoside phosphorylase, Np-1 and Np-2, or a regulatory-modifier locus.Entities:
