Tritrichomonas foetus and Trichomonas vaginalis: the pattern of inactivation of hydrogenase activity by oxygen and activities of catalase and ascorbate peroxidase

Article Abstract:

Trichomonas vaginalis and tritrichomonas foetus are the most studied organisms in a group of flagellated protozoans called trichomonads. However, previous research has failed to resolve two issues concerning the susceptibility of trichomonads to oxygen. Experiments are performed to resolve these issues. Results indicate that the oxygen inhibition profile of both organisms closely parallel oxygen inhibition of the in situ hydrogenase activity. It is also shown that ascorbate peroxidase is present in both organisms while catalase is present in only T. foetus.

The mycelium-associated Streptomyces reticuli catalase-peroxidase, its gene and regulation by FurS

Article Abstract:

The corresponding cpeB gene encoding the mycelium-related Streptomyces reticuli catalase-peroxidase was identified and sequenced by employing anti-CpeB antibodies and an expression. The gene was found to encode a protein of 740 aa with a molecular mass of 81.3 kDa. The deduced protein has the highest level of amino acid similarity with KatG from Caulobacter crescentus and Mycobacterium tuberculosis, and PerA from Bacillus stearothermophilus.

Characterization of Trichomonas vaginalis AP33 adhesin and cell surface interactive domains

Article Abstract:

Research was conducted to characterize Trichomonas vaginalis AP33 adhesin and cell surface interactive domains. One surface protein called AP33, which is one of the four parasite surface proteins mediating attachment to vaginal epithelial cells, was examined further to identify interactive domains. Two interactive domains were identified at the N-terminal half of AP33 and at the C-terminal third of the protein.
