Proteome compendium of the Antarctic krill (Euphausia superba) - Telson


ABSTRACT: The Antarctic krill provides central ecosystems services to the Southern Ocean grazing on autotroph and heterotoph diet and constituting the dominant food source for higher trophic levels. Moreover, E. superba's extensive equipment with biomacromolecule hydrolysing enzymes represents a largely untapped resource for applied purposes. The proteome compendium of krill provides a valuable basis for future studies on krill biology (e.g., metabolism, development, migration behaviour), for krill's contribution to organic matter turnover in the Southern Ocean, as well as for multilevel biotechnological prospecting.

The Antarctic krill (Euphausia superba Dana) is a keystone species in the Southern Ocean that uses an arsenal of hydrolases for biomacromolecule decomposition to effectively digest its omnivorous diet. The present study builds on a hybrid-assembled transcriptome (13,671 ORFs) combined with comprehensive proteome profiling. The analysis of individual krill compartments allowed detection of significantly more different proteins compared to that of the entire animal (1464 vs. 294 proteins). The nea  ...[more]
