This study reports the results of growth experiments with the freshwater prawn (Macrobrachium rosenbergii), using purified diets to establish the dietary requirements for lysine, arginine, methionine, and tryptophan. Four dietary levels of each amino

Transport of L-ascorbate by intestinal brush-border membrane vesicles of European eel Anguilla anguilla was stimulated by a transmembrane Na gradient (out > in) but not by a similarly directed gradient of K. Under short-circuited membrane potential c

The hepatopancreas of the American lobster (Homarus americanus) possesses four types of epithelial cells arranged along blind-ended tubules. At the distal tips of these tubules, stem cells termed E-cells differentiate into three other cell types, R-c

L-[3H]lysine uptake was measured in brush-border membrane vesicles prepared from intestinal mucosa of the European eel Anguilla anguilla. Lysine uptake occurred via 1) a nonsaturable component with an apparent diffusional permeability (P) of 0.58 mic

Epithelial brush-border membrane vesicles (BBMVs) from the hepatopancreas of the lobster Homarus americanus were prepared using a magnesium precipitation technique and employed in transport experiments designed to demonstrate the effects of external

The basolateral membrane of Atlantic lobster (Homarus americanus) epithelium possesses an electroneutral Na+/H+ antiporter that functionally resembles members of the vertebrate NHE family. Regulatory mechanisms of this antiporter in purified hepatopa

A plasma membrane H(+)-glycyl-L-proline (Gly-L-Pro) cotransport mechanism has been identified in isolated eel intestinal brush-border membrane vesicles (BBMV) by both measuring radiolabeled Gly-L-Pro uptake and monitoring Gly-L-Pro-dependent H+ influ
