Differences in the carapace astaxanthin proteins crustacyanins of the lobsters homarus americanus and homarus gammarus


, : Differences in the carapace astaxanthin proteins crustacyanins of the lobsters homarus americanus and homarus gammarus. Comparative Biochemistry & Physiology B 80(3): 599-602

The crustacyanins of H. gammarus and H. americanus, identical in absorption spectrum, behave differently in ion-exchange chromatography and polyacrylamide gel electophoresis. The carapace astaxantin-proteins of the separate species also have distinct subunit structures.

Examination of 42 testicular cells from H. americanus yielded a diploid chromosome number of 110 with a range of 94-185. The diploid number in H. gammarus was determined to be 95.5 with a range of 90.5-134.5. The meiotic chromosome number of H. am...

Acid digestive proteinases were studied in the gastric fluids of two species of clawed lobster (Homarus americanus and Homarus gammarus). An active protein was identified in both species as aspartic proteinase by specific inhibition with pepstatin...
