Casein kinase-2-type protein kinases in plants: possible targets of polyamine action during growth regulation?

The biochemical mechanisms by which polyamines influence plant growth and development are not known. One of mechanisms frequently proposed is that polyamines can bind to key cellular enzymes and modulate their activity. Polyamines have been reported to alter the activity of a number of enzymes in vitro. Among these the casein kinase-2 protein kinases are of… CONTINUE READING
