Chromosome localization of the loci GOT1, PP, NP, SOD1, PEPA and PEPC in the American mink (Mustela vison).

Twenty eight American mink × Chinese hamster somatic cell hybrids were analysed for the expression of mink enzymes and chromosome segregation. This analysis made it possible to assign the genes for glutamate-oxaloacetate transaminase-1 (soluble) (EC 2.6.1.1), inorganic pyrophosphatase (EC 3.6.1.1), purine nucleoside phosphorylase (EC 2.4.2.1) to mink chromosome 2, superoxide dismutase-1 (soluble) (EC 1.11.1.1) to chromosome 5, peptidase A (EC 3.4.11 or 3.4.13) to chromosome 4, and peptidase C (EC 3.4.11 or 3.4.13) to chromosome 13. It is suggested that the synthenic gene group GOT1-PP-NP is located on the short arm of mink chromosome 2.
