competition experiments using 9-anthroylcholine , a fluorescent dye that undergoes calmodulin-dependent binding by smooth muscle myosin light chain kinase [ malencik , d. a. , anderson , s. r. , bohnert , j. l. , & shalitin , y. s. ( 1982 ) biochemistry 21 , 4031 ] , demonstrate a strongly stabilizing interaction between the adenosine 5'-triphosphate and myosin light chain binding sites operating within the enzyme-calmodulin complex but probably not in the free enzyme .
