Properties of arginase from the sea mollusc Concholepas concholepas

Inhibition of rat liver and kidney arginase by cadmium ion

“…Arginase is activated by cadmium ion in tissue extracts from different organisms such as hepatopancreas of land snail [12], silk moth [13], bovine brain [14], rat liver, kidney, submaxillary gland, and brain [15,16], frog liver [17], sea mollusk Chiton latus [18] and bivalve clam Semele solida [19]. However, arginase is inhibited by cadmium ion in tissue extracts from axolotl liver [20], lupin [21], rat kidney [22], rat small intestine [23], barnacle rock shell Concholepas concholepas [24], common bean Phaseolus vulgaris [25] and zebra mussel Dreissena polymorpha [26].…”

Arginase kinetic characterization of the ­gastropod Nacella concinna and its ­physiological relation with energy­requirement demand and the presence of heavy metals

“…On the other hand, the foot muscle arginase was also activated by Co 2+ , the same activation was not observed in gills tissue (Figure 3a, b). Cations like Co 2+ have also been reported to activate some arginases, Carvajal et al (1984Carvajal et al ( , 1988 Tormanen (1997) observed the same activation in arginase of Zebra mussel.…”

“…It is also present in soils near stations which have used brass, steel coated nails and paints (Claridge et al, 1995;Webster et al, 2003), leaching of volcanic rocks also results in high levels of Fe 3+ and Zn 2+ (Ahn et al, 1999;Weihe et al, 2010 (Figure 4a, b). Carvajal et al (1984Carvajal et al ( , 1988Carvajal et al ( , 1994) observed inhibition of arginases by Zn 2+ in gills and foot muscle of…”
