A comparative study of the effect of carnosine on myofibrillar-ATPase activity of vertebrate and invertebrate muscle
1.
1. Carnosine and anserine activate rabbit skeletal muscle myofibrillar-ATPase activity.
2.
2. The total carnosine plus anserine found varies from species to species but is of the order of 20 μmoles per gram of tissue or greater.
3.
3. Invertebrate muscle, however, contains little or no carnosine or anserine.
4.
4. The effects of carnosine on the ATPase activity of myofibrils from rabbit and chicken skeletal muscle and from the muscle of eartworm, lobster and clam were compared.
5.
5. Carnosine had no activiating effect on the ATPase activity of the invertebrate systems in contrast to a two-fold activation of rabbit and chicken skeletal muscle myofibrillar-ATPase activity.
6.
6. The results indicate that carnosine activiation of myofibrillar-ATPase activity may be limited to myorfibrils from muscles that normally contain carnosine and/or anserine as major constituents.
