The role of creatine kinase and arginine kinase in muscle

Abstract: Arginine and creatine kinase activities in different muscles are compared with calculated maximum rates of ATP turnover. The magnitude of the kinase activities decreases in the following order: anaerobic muscles and vertebrate skeletal muscles greater than heart muscle greater than insect flight muscle. The maximum activity of phosphagen kinases (i.e. creatine kinase and arginine kinase), in the direction of phosphagen formation, is lower than the calculated maximum rate of ATP turnover in insect flight muscle… Show more

“…This is similar to the American locust, where mass-specific hopping metabolic rates are twofold higher in adults compared with juveniles (Kirkton et al, 2005). The high aerobic capacity of the adult hopping muscle is puzzling because it is inconsistent with the observation that its primary function is to perform single powerful jumps required to initiate flight (Katz and Gosline, 1993;Kirkton and Harrison, 2006): such short-term energy needs are more likely to be met by local ATP supplies that are temporarily maintained by arginine phosphate (Newsholme et al, 1978;Schneider et al, 1989). In light of this, it is possible that the high hopping metabolic rate of adult locusts could be due to the inadvertent stimulation of flight muscles during jumping exercise.…”

“…Para que ocorra rápida recuperação dos níveis iniciais de PCr (FIGURA 3), um dos mecanismos mais interessantes que se tem conhecimento é o efeito "shuttle" da PCr (paradoxo metabólico creatina fosfato), que está diretamente relacionado com a quantidade e a atividade da isoenzimas Mi-CK 18 .…”

“…Arginine kinase (ATP: L-arginine phosphotransferase, EC 2.7.3.3, AK) plays a critical role in cellular energy homeostasis in invertebrates by catalyzing a reversible transfer of phosphate from Mg·ATP to arginine, yielding phosphoarginine as follows: Mg·ATP + Arginine Phosphoarginine + Mg·ADP (Newsholme et al, 1978). AK only exists in the tissues of invertebrates (e.g., gut epithelial cells, muscle fibers, and neurons) (Lang et al, 1980;Chamberlin, 1997;Kucharski & Maleszka, 1998), and functions as a central regulator of temporal and spatial ATP buffers directly associated with muscle contraction, ATP regeneration and energy transport in cellular energy metabolism (Ellington, 2001).…”
