Targeting and translocation of proteins into the hydrogenosome of the protist Trichomonas: similarities with mitochondrial protein import.
Their thinking stems in large part from recently gathered information about the ancestry of the hydrogenosome. Observed for decades in cells as rodlike objects resembling mitochondria but lacking their own DNA, "they were looked at as a curiosity, an oddball organelle.
In the case of the trichomonads the proteins have been localized to the hydrogenosome (10), an energy-generating organelle that already had been suspected by some of having mitochondrial origins.

According to previous reports, lactate, formate, ethanol and succinate were formed in the cytosol of anaerobic fungi, and acetate, formate and [H.sub.2]/C[O.sub.2] were formed in the hydrogenosome (O'Fallon et al., 1991; Akhmanova et al., 1999; Boxma et al., 2004).

The anaerobic fungi are amitochondrial organisms and have a hydrogenosome instead for energy production (Yarlett et al., 1986).
Parabasalia are clearly secondarily amitochondrial, since their hydrogenosomes probably evolved from mitochondria by the loss of cytochromes and DNA; protein phylogeny ((4); Hasegawa, pers.
Some one-celled creatures depend on such organisms to take the hydrogen, along with other products, from the hydrogenosomes and turn it into user-friendly metabolites for the host cell (SN: 4/18/98, p.
The Parabasalia is composed of flagellated anaerobic protists defined by the presence of hydrogenosomes, flagellar apparatus, parabasal body, and parabasal filament.
