Description: This entry represents Spo11, a meiotic recombination protein found in eukaryotes, and subunit A of topoisomerase VI, a type IIB topoisomerase found predominantly in archaea [, , , ]. These two types of proteins share structural homology.DNA topoisomerases regulate the number of topological links between two DNA strands (i.e. change the number of superhelical turns) by catalysing transient single- or double-strand breaks, crossing the strands through one another, then resealing the breaks. They can be divided into two classes: type I enzymes (, topoisomerases I, III and V) break single-strand DNA, and type II enzymes (, topoisomerases II, IV and VI) break double-strand DNA []. Topoisomerase VI is a type IIB enzymes that assembles as a heterotetramer, consisting of two A subunits required for DNA cleavage and two B subunits required for ATP hydrolysis. The B subunit is structurally similar to the ATPase domain of type IIA topoisomerases, but the A subunit is distinct, and instead shares homology with the Spo11 protein. Spo11 is a meiosis-specific protein that is responsible for the initiation of recombination through the formation of DNA double-strand breaks by a type II DNA topoisomerase-like activity. Spo11 acts in conjunction with several other proteins, including Rec102 in yeast, to bring about meiotic recombination [].

Type: Family
Description: Rec104 is one of several meiosis specific genes required for generating meiotic DSBs (double strand breaks) []. It is suggested that Rec102 and Rec104 directly promote DSB formation as part of a multiprotein complex with Spo11. Rec102 and Rec104 are mutually dependent for proper sub-cellular localization, and share a requirement for Spo11 and Ski8 for their recruitment to meiotic chromosomes. Moreover, Rec102 is required for Rec104 to accumulate to normal steady-state levels and to be properly phosphorylated. It is likely that Rec102 and Rec104 move freely in and out of the nucleus but are most stably sequestered there only when they can form a complex on chromosomes [].

Description: This topoisomerase-primase (TOPRIM) nucleotidyl transferase/hydrolase domain is found in the type II topoisomerase VIA and Spo11. This subgroup contains proteins similar to Sulfolobus shibatae topoisomerase VIA (TopoVIA) []and Saccharomyces cerevisiae meiotic recombination factor Spo11 []. Type II DNA topoisomerases catalyze the ATP-dependent transport of one DNA duplex through another, in the process generating transient double strand breaks via covalent attachments to both DNA strands at the 5' positions. TopoVI enzymes are heterotetramers found in archaea and plants [, ]. Spo11 plays a role in generating the double strand breaks that initiate homologous recombination during meiosis [, ]. S. shibatae TopoVI relaxes both positive and negative supercoils, and in addition has a strong decatenase activity [].The TOPRIM domain has two conserved motifs, one of which centres at a conserved glutamate and the other one at two conserved aspartates (DxD). For topoisomerases, the conserved glutamate is believed to act as a general base in strand joining, and as a general acid in strand cleavage []. The DXD motif may co-ordinate Mg2+, a cofactor required for full catalytic function.

Protein Domain
Type: Family
Description: The representative of this plant family is PAIR1 (HOMOLOGOUS PAIRING ABERRATION IN RICE MEIOSIS1), a protein that plays an essential role in establishment of homologous chromosome pairing in meiosis. Mutations in the gene encoding this protein also affect spindle formation and sporulation []. This family also contains the Putative recombination initiation defects 3 (AtPRD3) involved in the meiotic recombination initiation [].In flowering plants, gametophyte formation relies on meiosis. In meiosis I, the homologous chromosomes are separated into two daughter cells. In meiosis II, the sister chromosomes are then separated into newly formed daughter cells. During prophase I, several events occurs: sister chromatid cohesion, homologous chromosome synapsis, recombination, crossover formation and chromosome segregation. Homologous recombination is initiated from the formation of DNA double-strand breaks (DSBs). The formation of DSBs is catalyzed by Spo11 and its homologues. So far, six Arabidopsis proteins, AtSPO11-1, AtSPO11-2, AtPRD1, AtPRD2, AtPRD3 and AtDFO, have been shown to be involved in DSB formation [].

Description: DNA topoisomerases regulate the number of topological links between two DNA strands (i.e. change the number of superhelical turns) by catalysing transient single- or double-strand breaks, crossing the strands through one another, then resealing the breaks []. These enzymes have several functions: to remove DNA supercoils during transcription and DNA replication; for strand breakage during recombination; for chromosome condensation; and to disentangle intertwined DNA during mitosis [, ]. DNA topoisomerases are divided into two classes: type I enzymes (; topoisomerases I, III and V) break single-strand DNA, and type II enzymes (; topoisomerases II, IV and VI) break double-strand DNA [].Type II topoisomerases are ATP-dependent enzymes, and can be subdivided according to their structure and reaction mechanisms: type IIA (topoisomerase II or gyrase, and topoisomerase IV) and type IIB (topoisomerase VI). These enzymes are responsible for relaxing supercoiled DNA as well as for introducing both negative and positive supercoils [].This entry represents subunit B of topoisomerase VI, a type IIB topoisomerase found predominantly in archaea, but also in a few eukayotes, such as the plant Arabidopsis thaliana []. This enzyme assembles as a heterotetramer, consisting of two A subunits required for DNA cleavage and two B subunits required for ATP hydrolysis. The B subunit is structurally similar to the ATPase domain of type IIA topoisomerases, but the A subunit is distinct, and instead shares homology with the Spo11 protein that mediates double-strand DNA breaks during meiotic recombination in eukaryotes []. Therefore, though related to type IIA topoisomerases, topoisomerase VI may have a distinctive mechanism of action.
