Regulation of tail muscle hexokinase in the anoxia-tolerant freshwater crayfish, Orconectes virilis
Hexokinase (HK)(E.C.2.7.1.1) is the enzyme responsible for catalyzing the first step of glucose metabolism, the phosphorylation of glucose to glucose-6-phosphate (G6P). The present study investigated HK from tail muscle of the freshwater crayfish Oconectes virilis exploring changes to kinetic properties, phosphorylation levels and structural stability between two forms of the enzyme (aerobic co...
متن کاملGlucose-6-Phosphate Dehydrogenase Regulation in Anoxia Tolerance of the Freshwater Crayfish Orconectes virilis
Glucose-6-phosphate dehydrogenase (G6PDH), the enzyme which catalyzes the rate determining step of the pentose phosphate pathway (PPP), controls the production of nucleotide precursor molecules (R5P) and powerful reducing molecules (NADPH) that support multiple biosynthetic functions, including antioxidant defense. G6PDH from hepatopancreas of the freshwater crayfish (Orconectes virilis) showed...

متن کاملMercury in the northern crayfish, Orconectes virilis (Hagen), in New England, USA.
Biologists and policy makers continue to seek environmental correlates of mercury bioavailability in aquatic ecosystems. In this study, we assessed the effects of drainage basin, habitat type, size class, and sex on mercury concentrations in the northern crayfish, Orconectes virilis (Hagen). Drainage basin, habitat type, and size class had significant effects on mercury concentration in crayfis...
