Interpopulation Differences in Red Blood Cell Enzyme Levels of the Wallaroo Macropus Robustus (Marsupialia)

Abstract

The levels of six glycolytic enzymes were studied in three different populations of M. robU8tU8. Significant interpopulation differences were found for five of the enzymes. Glucose-6-phosphate dehydrogenase levels are up to three times higher than those found in eutherians. Keto-I-phospha.te aldolase substrate specificity differs radically from that found in eutherians. The enzymes studied are independently regulated.
