the enzyme from skeletal muscle is susceptible to seasonal alterations: in autumn and winter, NADP+ synthesis proceeds maximally in the cytoplasm, in spring, higher activity is found in the mitochondrial fraction
the Ca2+-calmodulin-dependent NAD+ kinase isoforms, amongst which is the isoform bound to mitochondrial membranes play an important role at the end of sensu stricto germination and during the following growth of Avena sativa
five forms of NAD+ kianse: 1. a solvent Ca2+ sensitive form, 2. and 3. two Ca2+-calmodulin independent forms, one solvent and one membranal, 4. and 5. two Ca2+-calmodulin dependent forms, one solvent and one membranal. In dry seeds the membranal-Ca2+-calmodulin-dependent form represents 100% of the total pelletable activity
