Function

[GST26_SCHJA] Conjugation of reduced glutathione to a wide number of exogenous and endogenous hydrophobic electrophiles. GST isoenzymes appear to play a central role in the parasite detoxification system. Other functions are also suspected including a role in increasing the solubility of haematin in the parasite gut.

Publication Abstract from PubMed

Dyneins power the beating of cilia and flagella, transport various intracellular cargos and are necessary for mitosis. All dyneins have a approximately 300-kDa motor domain consisting of a ring of six AAA+ domains. ATP hydrolysis in the AAA+ ring drives the cyclic relocation of a motile element, the linker domain, to generate the force necessary for movement. How the linker interacts with the ring during the ATP hydrolysis cycle is not known. Here we present a 3.3-A crystal structure of the motor domain of Saccharomyces cerevisiae cytoplasmic dynein, crystallized in the absence of nucleotides. The linker is docked to a conserved site on AAA5, which is confirmed by mutagenesis as functionally necessary. Nucleotide soaking experiments show that the main ATP hydrolysis site in dynein (AAA1) is in a low-nucleotide affinity conformation and reveal the nucleotide interactions of the other three sites (AAA2, AAA3 and AAA4).
