| - | + | [https://www.uniprot.org/uniprot/VATA_YEAST VATA_YEAST] Catalytic subunit of the peripheral V1 complex of vacuolar ATPase. V-ATPase (vacuolar ATPase) is responsible for acidifying a variety of intracellular compartments in eukaryotic cells. It is an electrogenic proton pump that generates a proton motive force of 180 mV, inside positive and acidic, in the vacuolar membrane vesicles. It may participate in maintenance of cytoplasmic Ca(2+) homeostasis. This is a catalytic subunit.<ref>PMID:1534148</ref> PI-SceI is an endonuclease that can cleave at a site present in a VMA1 allele that lacks the derived endonuclease segment of the open reading frame; cleavage at this site only occurs during meiosis and initiates "homing", a genetic event that converts a VMA1 allele lacking VDE into one that contains it.<ref>PMID:1534148</ref> | |

| - | PI-Scel is a bifunctional yeast protein that propagates its mobile gene by catalyzing protein splicing and site-specific DNA double-strand cleavage. Here, we report the 2.4 A crystal structure of the PI-Scel protein. The structure is composed of two separate domains (I and II) with novel folds and different functions. Domain I, which is elongated and formed largely from seven beta sheets, harbors the N and C termini residues and two His residues that are implicated in protein splicing. Domain II, which is compact and is primarily composed of two similar alpha/beta motifs related by local two-fold symmetry, contains the putative nuclease active site with a cluster of two acidic residues and one basic residue commonly found in restriction endonucleases. This report presents prototypic structures of domains with single endonuclease and protein splicing active sites. | ||
