Distribution of Calmodulin-Dependent and Calmodulin-Independent NAD Kinase During Early Cell Development in the Root Apex of Pisum Sativum
Two forms of NAD kinase activity are detectable in shoot and root tissues of Pisum sativum. Detection and separation of the two forms are both dependent on extraction conditions. A Ca2+-CaM-independent component can be extracted by gentle homogenisation conditions, whereas an additional Ca2+-CaM-dependent component is dependent on the presence of high salt concentrations during homogenisation.
