Activating Compound

Activating Compound Comment Organism Structure
Calmodulin two peaks of calmodulin-dependent NAD+ kinase activity occur at times when the cells are not actively dividing: the first one, a few hours after medium inoculation and the second one, at the end of the exponential growth phase Solanum pimpinellifolium
