Glutamine synthetase: assimilatory role in liver as related to urea retention in marine chondrichthyes

JT Webb and GW Brown Jr

The levels of gluatmine synthetase specific activity in hepatic and renal tissue are higher in fish that are ureosmoregulators than in those that are not. Enzyme activities in the liver and kidney of 18 species of fish correlated directly with the ureosmoregulatory adaptation of each species.
