Experimental evidence for enzymatic cell wall dissolution in a microbial protoplast feeder (Orciraptor agilis, Viridiraptoridae).

ABSTRACT:

Background

Several protists have evolved the ability to perforate the cell walls of algae and fungi to specifically feed on their cell contents. These phagotrophic "protoplast feeders" represent an interesting mechanistic intermediate between predators and parasites and pose a number of cell biological questions. Although their fascinating feeding behaviour has been observed for the last 150 years, it is still unknown how protoplast feeders produce the well-defined and species-specific perforations in biochemically diverse cell walls. Differential expression analyses of the algivorous flagellate Orciraptor agilis (Viridiraptoridae, Cercozoa, Rhizaria) suggested the involvement of a highly expressed putative glycoside hydrolase of family GH5_5. To assess the importance of this carbo
