... as an osmoconformer in seawater). Additionally, expression of ion transporters and supporting enzymes that typically undergo upregulation during salinity transfer in osmoregulatory gills (i.e. Na + /K + -ATPase, carbonic anhydrase, Na + /K + /2Cl − cotransporter, V-type H + -ATPase and arginine kinase) were generally...

... granulatus following transfer from isosmotic conditions (30‰salinity) to either dilute (2‰) or concentrated (45‰) seawater. Modest changes were observed in the abundance of mRNAs encoding the housekeeping protein arginine kinase and the vacuolar-type H + -ATPase B-subunit, both of which were highly expressed...

.... The present study demonstrates that primmorphs from the demosponge Suberites domuncula express the gene for arginine kinase after exposure to exogenous silicic acid. The deduced sponge arginine kinase sequence displays the two characteristic domains of the ATP:guanido phosphotransferases; it can be grouped...

...Deanne M. Compaan; W. Ross Ellington SUMMARY Arginine kinase (AK) from the foot of the razor clam Ensis directus consists of two full-length AK domains, denoted D1 and D2, fused in a single polypeptide chain. The full-length cDNA for Ensis AK was obtained and its deduced amino acid sequence...

...Stewart M. Holt; Stephen T. Kinsey SUMMARY Flux was examined through the reaction catalyzed by arginine kinase in intact blue crab ( Callinectes sapidus ) muscle during simulated changes in salinity. Isolated dark levator muscles from the swimming leg were superfused with a saline solution that had...

...Munenori Noguchi; Taketoshi Sawadah; Toshikazu Akazawa ABSTRACT The energy supply for eukaryotic ciliary and flagellar movement is thought to be maintained by ATP-regenerating enzymes such as adenylate kinase, creatine kinase and arginine kinase. In this study, the energy-supplying system...

... high and variable demands on their reserves of high-energy phosphates. The major invertebrate phosphagen kinase, arginine kinase, is expressed in the gills of two species of euryhaline crabs, the blue crab Callinectes sapidus and the shore crab Carcinus maenas , in which energy-requiring functions...

...M. E. Chamberlin ABSTRACT Mitochondria isolated from the posterior midgut of the tobacco hornworm ( Manduca sexta ) contain arginine kinase. The distribution of mitochondrial and cytoplasmic marker enzymes indicates that the presence of mitochondrial arginine kinase is not due to cytoplasmic...

... arginine kinase creatine kinase muscle echinoderm One puzzling feature about the distribution of phosphagen kinases is the occasional presence of more than one phosphagen type in a given tissue, the so-called ‘pluriphosphagen’ phenomenon ( Robin, 1964 ). For instance, many species of polychaetes...
