these results therefore suggest that g-actin interacts with the enzyme molecule at the binding site ( s ) different from that involved in actin polymerization , and that it causes the activation of the soluble enzyme as a result of an allosteric alteration in the enzyme structure , thus giving rise to the possibility that cytoskeletal elements play an important role in the regulation of catecholamine synthesis as a factor modulating the activity of cytoplasmic tyrosine hydroxylase .
