Rhythmic changes in the activities of NAD kinase and NADP phosphatase in the achlorophyllous ZC mutant of Euglena gracilis Klebs (strain Z).

Abstract excerpt

NAD kinase and NADP phosphatase activities were detected in the supernatant and the pellet fractions prepared by sonication and centrifugation of the achlorophyllous ZC mutant of the phytoflagellate Euglena gracilis. A detailed study of substrate concentration-velocity curves enabled us to define the saturating substrate concentrations that were used in the enzyme assays. An analysis of the reproducibility of the...
